How to Bleed Your Shimano Brakes for Optimal Stopping Power

You've probably heard of bleeding brake fluid before, but did you know that it's also important to bleed your brakes after every ride?

Brakes are designed to stop your bike from moving forward, but they don't always work perfectly. Breathing your brakes is necessary if you notice them not working properly, or if they start to wear out.

Bleeding brakes is a simple procedure that involves pumping brake fluid into the reservoir at the back of the caliper. This helps clear air bubbles and other contaminants from inside the system.

Shimano brake pads are designed to last longer than other brake pads and provide better stopping power. Bleeding your brakes regularly will extend their lifespan, and this video will show you how to bleed Shimano brakes.

Able to stop a car from moving forward or backward, braking systems are essential parts of vehicles. The braking system consists of brake pads, calipers, and rotors, and these components come together to form a complete braking system.

"Bleeding" refers to removing air bubbles and moisture from the brake system. When air bubbles get trapped inside the brake pad, they cause friction between the pad and rotor, and this causes heat buildup and premature wear of the brake pads.

How Can I Bleed a Shimano Brake?

Shimano brakes are a great option for those who want to take their mountain biking to the next level, but they are not super simple to bleed.

Bleeding brakes is easier than it seems and can be done with the same tools to bleed front brakes.

To avoid introducing air bubbles, use a syringe instead of a tube if bleeding the rear brakes.

Put your Bike in a Work Stand

The bike should be placed on a work stand in a spacious area to bleed brakes.

Bike levers must be parallel to the ground for easy brake bleeding.

The bar clamp should be tightened first to prevent fluid from spilling out.

Take out the wheel.

To bleed the brakes, you need to remove the wheel.

To remove the brake pads, use a cotter pin and a 3 millimeter Allen key.

Keep the brake pads away from Shimano mineral oil.

Remove the brake pads.

To remove brake pads, you need a different tool depending on the type of brake.

Cotton pins and bolts keep brake pads in place when they are squeezed, and removing them provides access to the brake pads.

If you're bleeding the front brake, remove the front wheel. If you're bleeding the rear brake, remove the rear wheel.

Remove the cotter pin and bolt using an Allen wrench, and set the brakes out of the way so as not to contaminate them with mineral oil.

  • Bleed Block (if applicable) must be installed before proceeding; 
  • adjusting level brakes helps increase air bubbles that rise to the top;
  • remove the bleed fitting screw with 2 5 mm Allen wrench;
  • thread Shimano brake bleed funnel into bleed nipple;
  • fill the syringe with mineral oil and place on the bleed nipple;
  • open bleed fitting using 7 mm box wrench;
  • remove the plunger from Shimano bleed funnel and push fluid through the system while closing off bleed fitting;
  • add suction to syringe to avoid splashing.

To bleed the brakes, remove the brake pads and plunger; bleed the Brake Lever and Caliper.

Clean the components with Isopropyl Alcohol

Reinstall Pad/Plunger/Bleed Block

Install the Bleed Block

To bleed your Shimano hydraulic disc brakes, you will need to install a Bleed Block.

Depending on your brake type, the Bleed Block is secured with a cotter pin or bolt.

To adjust the brake lever level and clear air bubbles from the system, remove the bleed fitting screw and thread in the Shimano bleed funnel.

Put the syringe on the bleed nipple after opening the bleed fitting with a 7 mm box wrench.

Remove remaining air bubbles by alternately pulling and flicking on the brake lever while filling up the syringe as needed until all gas bubbles are gone.

Replace bleeder screws at both lever and caliper sides, and clean brake lever and caliper with isopropyl alcohol.

Level the Brake Lever

Avoid air bubbles entering the brake system by adjusting the brake lever safely.

Remove the wheel from the caliper you plan to work on

Leave the brake pads in when pushing pistons back

Remove pad retaining pin

Insert pad spacer and secure with a pin

Level brake lever to avoid unwanted air bubbles entering the system

Carefully insert bleed bucket ensuring not to over tighten bucket

Remove any air bubbles from the syringe

Depress syringe while watching bucket until mineral oil runs clean and bubble-free

Clean and insert new brakes pads.

Remove air bubbles by alternately pumping and flicking the brake lever.

Replace the plunger and funnel.

The lever and caliper should be fitted with bleed fitting screws.

Use a rag to clean brake levers and calipers with isopropyl alcohol.

Brake pads should be reinstalled with a cotter pin or bolt after removing the Shimano brake bleed block.

Reinstall the rear wheel if needed; repeat for the front-wheel if necessary.

Take Out the Bleed Fitting Screw

Also known as the bleed port screw, the bleed fitting screw holds the bleed fitting in place.

Using an Allen wrench and syringe, remove the bleed fitting screw.

Remove the syringe from the bleed nipple and close the bleed fitting at the lever reservoir.

To prevent sudden damage, you will need to replace the Bleed port screws at the brake lever and caliper sides with clean threads.

Introduce the Shimano Bleed Cup

The Shimano bleed cup is essential to bleeding your brakes.

The syringe is the easiest way to do this, but other tools are available if needed.

Make sure to get all of the necessary tools before starting.

Fill the Syringe with the Mineral Oil

After taking the brake lever off, use a 7mm Allen wrench to remove the bleed fitting.

Let mineral oil flow into the brake lever reservoir by opening the bleed port at the caliper.

An eighth of a turn of a 7mm wrench is all that is needed to open the bleed port at the caliper, then fill up the catch bottle with dirty mineral oil.

As mineral oil drips out of the bleed cup, top it off. Avoid introducing air into the system through either open end.

Oil will flow out of the caliper when you hold the brake lever closed and pull it--release the lever blade, tighten the bleed port again, and repeat until it is all gone.

After measuring the mineral oil, pour it into the syringe.

Insert the syringe's needle into one end of the tube and slowly push until liquid comes out of the syringe.

Hold onto the other end of the tube while you squeeze on top of it with your hand to force more fluid from the caliper.

Once all fluid is extracted, release pressure from both sides of the caliper by gently pulling up on it until it snaps off (or pops open).

Discard used calipers and mineral oil in a safe place

Push the fluid into your Brake System

Bleed your brakes by removing the plunger from the bleed cup and pushing fluid through the brake system.

Fill the bleed cup with mineral oil until clean, fresh oil begins to come out of the caliper, then top off the cup.

Make sure air doesn't enter your brake system by closing both ends of the brake system before pushing fluid through the line using the brake lever.

Bleed the brakes by opening the bleed port and letting fluid escape.

Do this a few times until the system is clear.

Be careful not to over-bleed the system.

Remove the syringe.

Use a syringe and mineral oil to bleed the brake system on a Shimano bike.

Ensure the oil you use is from the Shimano hydraulic mineral oil line.

After bleeding, check the fluid level in the bleed cup to ensure everything is working correctly.

Get Rid of Remaining Air Bubbles

To remove remaining air bubbles from the brake system, level the lever position and fill the bleed cup halfway.

Use a 7mm spanner to loosen the brake handlebar clamp and open the free stroke screw by two turns.

Pump the brake lever to see air bubbles rise to the top and then loosen the brake handlebar clamp with Allen keys.

Add mineral oil to the bleeding bucket (aka Shimano SM-DISC) if needed and bleed brakes according to the manufacturer's instructions.

Remove the Bleed Cup

To remove the bleed cup, first, take out the plunger.

Replace the bleed port screws at the lever and brake caliper sides.

Make sure each bleed screw is clean.

Install the bleed cup in the brake lever and fill it with Shimano hydraulic mineral oil.

Please make sure that the bleed cup is not cross-threaded into the lever. Due to the plastic threads, they are easily damaged if not handled carefully.

The bleed cup should have an O-ring at the bottom to ensure a great seal. The absence of this may result in air being introduced into the brake line.

Clean Everything

Clean the brake lever, caliper body, and brake line with alcohol.

You should close the brake caliper's bleed port using an open-ended wrench.

Remove the oil catch bottle and clean the leaking oil. Dispose of dirty oil.

Mineral oil should be kept away from brake pads

Clean off brake caliper before installing brakes using Finish Line Citrus Bike Degreaser 6 Install brakes using 3mm Allen key

Reinstall the Parts you Removed

The brake bleed process is now finished, so you have to put everything back to the way it was.

Install brake pads with the cotter pin or bolt to make them contact the rotor with no trouble.

After doing that, reattach the wheel to the bike. Repeat that process for the front brakes.

Be careful enough when setting it up, or get your trusted local bike store to assist you with the changes.

You can reinstall the parts you removed by following the instructions in this guide.

How To Bleed Shimano Road Hydraulic Disc Brakes

Shimano Road Hydraulic Disc Brakes are known for their durability and performance. However, like any other braking system, they can be susceptible to brake failure if not maintained properly. Shimano Road Brakes can be maintained by following these simple steps.

First, remove the hose from the brake caliper to bleed hydraulic disc brakes.

Park your bike so that the wheel is facing down and the chain is off the ground.

Liberalize (open) the bleed screw on top of the caliper with a flathead screwdriver or hex wrench. Keep an eye on oil pressure while bleeding, as too much oil can damage valves.

Bleed brakes slowly by turning the bleed screw in a counterclockwise direction until all water has been expelled from brake pads and lines or until there's no more noise coming from under your bike when you pedal.

Tighten bleed screw once all water has been expelled: turn it clockwise one full turn.

Replace the hose and replace the brake caliper.

Shimano road hydraulic disc brakes are susceptible to bleeding in wet conditions.

Bleeding can cause the brakes to stop working and may require replacement.

To prevent bleeding, make sure the brake pads are properly seated and correctly assembled the caliper.

Cleaning the bleeding area with a damp cloth and clear water, then applying brake fluid, will help prevent future bleeding.

Repeat this process until the bleeding stops.

Bicycle prep

Remove the wheel and rotate the bike for an upward slope to brake tubing.

Remove the brake pads from the caliper.

Install bleed blocks between pistons.

Prepare the BKM-1 kit.

You will need an open-ended hose (part #2593) and an angled hose (part #2594). Ensure the hose is snugly attached to the syringe before use. Over the open end of the hose, slide the compression sleeve (part #2588).

The brake fluid should be filled about two-thirds of the way into this syringe. The appropriate brake fluid should be filled about two thirds of the way into this syringe.

The plunger should be slowly and gently pushed until fluid reaches the end of the tubing when held upright

7 Place the syringe in the syringe holder.

Bicycle prep includes cleaning and lubricating the bike

Checking brakes, gears, and chain

Adjusting seat and handlebars

Loading the bike into the trailer

Driving to destination

Rotate Levers

Hydraulic brake levers from Shimano feature internal channels connecting to fluid reservoirs.

It is therefore necessary to rotate the lever at certain angles so that all air is expelled from the lever. There will be a different amount of rotation depending on the model.

Defining the position of the bleed port is made easier by Shimano's reference marks.

It is important to avoid damaging any internal wires when rotating bars.

Rotate the levers to change the intensity of sound.

The sound level can be adjusted from whisper to full blast.

The earphones come with three different sizes of ear tips for a custom fit.

Use the headphones at home or take them on the go for peace of mind when listening to your favorite music or movies anywhere!

Inject Fluid

To inject fluid into the brake system, you must first remove the plug from the filling port.

You should fill approximately ¾ of the fluid reservoir with fresh fluid before replacing the plug.

Rotate Levers (Top Port Gen 2 Only)

The levers for the Top Port: Generation 2 style are rotated to make the lever reference line 45 degrees upward.

The fluid is drained back down to exit at the caliper by squeezing the lever a few times and inspecting for bubbles.

The bars are then tilted so that the lever surface behind the port is level to the ground, placing the funnel 45 degrees forward from vertical. Make sure there are no bubbles visible after squeezing the lever several times.

To rotate the top port, use the lever on the side of the machine.

To rotate the bottom port, use the lever on the front of the machine.

The top and bottom ports can be rotated in either direction to adjust your grinds accordingly.

When grinding with a burr, it is important to keep your fingers clear of any moving parts, so you don't damage them or your beans.

Cleaning your grinder regularly will prevent clogging and reduce performance issues.

Drain Fluid

Loosen the caliper bleed nipple and screw 1/2 turn to drain fluid from the brake system.

Start the flow of fluid from the Bleed funnel through the caliper and through the waste hose by gently squeezing the lever.

Be sure to tap along the length of the hydraulic hose and the caliper to dislodge any bubbles. You should keep an eye on the bleed funnel and make sure it does not run out of fluid. If necessary, add fluid to the bleed bottle to prevent the brake lever port from allowing air to enter.

When no more bubbles appear in the drain hose, close the bleeder nipple.

6 Remove plug and fill approximately ¾ with fresh fluid.

Pressurize System

Bleed brakes to remove air bubbles and restore pressure

Open caliper bleed port an eighth of a turn

Add oil to the bleed cup to prevent air sneaking into the system.

  • adjust Brake Levers and Cables
  • check for wear and tear on braking surfaces

Bleeding Shimano road brakes can be done with a bleeding kit

It is possible to bleed Shimano road brakes with a bleeding kit. This guide will show you how to do it. The process is relatively simple and can be done in minutes.

The bleeding kit should include a pad, plunger, and rubber band.

To bleed Shimano brakes, the first step is to gather the necessary supplies. The bleeding kit should include a pad, plunger, and rubber band. Next, remove the brake lever from the handlebar and find the bleed port.

Push the plunger into the bleed port and attach the pad to hold it in place. Finally, use a rubber band to keep tension on the plunger while pumping it up and down.

The plunger is used to remove air from the system.

When it comes to bleeding Shimano brakes, you will need a few things: brake calipers, bleed kit, cable cutter, 10 mm wrench, and a plunger.

First, cut the old brake cable near the caliper using the cable cutter. 

Next, remove the brake pads by unscrewing the pad retaining screws with a 10 mm wrench.

After that, use the plunger to push all of the air out of the system and into your waste container.

Finally, reattach the brake pads, screw on the pad retaining screws, and attach the new brake cable.

Place the pad over the bleed hole and attach the rubber band around it

To bleed Shimano road brakes, you need to place the pad over the bleed hole and attach the rubber band around it. This will create a seal and allow you to pump the brake lever without any air escaping.

Push and pull on the rubber band until all fluid is drained

Replace the bleed screw and tighten it by hand when you're done. There's no need to overdo it – make sure it's snug.

Now, reattach the brake cable (making sure the cable is properly seated in the anchor bolt) and test your brake lever before taking your bike for a test spin.

To finish up, give the wheel a spin and watch how the rotor moves. If everything looks good congratulations! You've successfully bled your Shimano brakes.

Frequently Asked Questions (FAQ) on Shimano brake bleeding.

How Often Should You Bleed Shimano Hydraulic Disc Brakes?

Shimano hydraulic disc brakes are one of the most popular brakes on the market. They are reliable and offer great stopping power.

However, like all brakes, they need to be bled occasionally to keep them in good working order. Bleeding a Shimano hydraulic disc brake removes the cap and releases the brake fluid.

Bleeding Shimano Hydraulic Disc Brakes How Often?

If you ride a bike with Shimano hydraulic disc brakes, it's important to bleed the brakes regularly. Bleeding the brakes flushes out any air that may have built up in the system and helps to keep your brakes operating at their best.

Shimano disc brakes need to be bled how often?

Shimano disc brakes are brakes that use pads to stop a bicycle. When you use them, the brake pads will become wet from the fluid used to make them work, and this fluid needs to be bled every so often to keep the brakes working properly.

How much mineral oil to bleed Shimano brakes?

Shimano brake pads use mineral oil as a lubricant. Mineral oil is a petroleum-based product that can be thinned with water or other liquids to create a working fluid.

The amount of mineral oil that needs to be bled from Shimano brake pads depends on the type of brake pad, the amount of wear on the pad, and the temperature. Generally, 1 ounce (30 milliliters) of mineral oil should be bled per quart (1 liter) of fluid.

Can I use car mineral oil to bleed my Shimano mountain bike brakes?

Using different brake fluids can affect your brake's performance in different ways, so there is no definitive answer to this question.

However, it is generally safe to use car or motor oil as a substitute for brake fluid on mountain bike brakes. This is because motor oil is synthetic oil and is not affected by water or moisture like brake fluid can be.

Additionally, motor oil has a higher boiling point than brake fluid, which will heat up more quickly and cause the brakes to work harder than they would if they were using brake fluid that was hot enough to work properly.

How do you bleed Shimano disc brakes without a kit?

There are a few ways to bleed Shimano disc brakes without a kit. The most common way is to use a hose clamp and a standard bleed kit.

Turn the bleed screw until the disc brake bleeds freely, and clamp the hose onto the bleed screw on the disc brake. Be careful not to over-bleed the brakes, or they may become inoperable.

How do you bleed Shimano brakes without a syringe?

In the absence of a syringe, you can suck out the brake fluid using a vacuum cleaner. Make sure to use a rubber hose to avoid damaging the brake line.


This is an important step because it ensures that your brake pads are working properly. If your brakes are not properly bled, you could damage your rotors or even cause serious injury.

Taking care of brake bleeding is a straightforward process that takes less than 10 minutes, although a few tools are needed and practice is required. We have shown you how to bleed Shimano brakes in this guide.
