When Do You Need to Bleed Your Motorcycle Brakes?


Just like a disease, when you suspect that your motorcycle brakes might need to be bled, you have to pay close attention to observing the symptoms. The first and most obvious symptom that your eye will catch and what you will feel is that the braking power will be significantly reduced.


Inconsistent and wonky braking is another clear symptom that your brakes need to be bled. Along with that, if you feel a soft and spongy sensation in the lever, you might want to get your system checked to put a spotlight on the problem.


Bleeding your motorcycle brakes is not something that must only be done when there is air in the line. It is something that any bike owner should do over a certain period as a step of proper maintenance.


TIP: Before you begin doing anything, we would advise you to carefully go through the service manual of your model, which you can easily find on the internet.


In this manual, you will find some special specifications about torque and the brake fluid that might come in handy while you are in the middle of the job.

Here’s the step-by-step process for you:

Step 1: Securing the Motorcycle

To start, you have to secure your motorcycle in a steady and manageable position. To prevent your bike from toppling over and breaking your joints, you should place it on its center stand.

Step 2: Filling the Brake Fluid and Protecting the Paintjob

Firstly, you need to take off the cap of the reservoir and then top off the brake fluid almost to the brim. You could put some rags to soak up any spillages and avoid any damage.

Step 3: Pumping

The third step is to keep on pumping the brake handle; the piston will move to indicate you to stop. Use a C-clamp to keep the piston in place if there is only one. However, if there is another one to be handled, then you have to keep on pumping, and alongside that, you must shift the c-clamp between the two pistons.


Keep a close eye at the reservoir to make sure that it is full. If it is necessary, pour in some extra bit of brake fluid. This step is important because it drains out the toxic fluids.

Step 4: Bleeding the Brakes

Now, this is the real deal, the main step of the entire process, the part that needs the most attention, and the one that determines everything. Begin by placing the caliper and pistons right back to their original positions. To lubricate it and make things smoother, you might want to use some brake fluid.


Grab a hose and place one of its ends into the cover of the bleed, and the other end into something like a bucket. Release the bleed screw to let out air contaminated fluid cautiously on the caliper. Twist the screw right back in and start pumping for a bit until all the air is completely removed from the brake fluid.


We will suggest you tap the hose and bleed screw to let out any air bubbles overnight. You do not need to worry as the set up can be left like it is unaffected overnight.


DISCLAIMER: The process of bleeding brakes can test your temper at times, so try to be as patient as you can.

Step 5: Testing It out

When you have completed bleeding your brakes, take a look at the reservoir again to see if it is on the upper line. With care, put the diaphragm back in. Close the cap and place all the other components right into place.


After making sure that you have put everything into place, move the bike to and fro to check if everything is working smoothly. If it is, then take it out for a test drive to see if it is comfortable to ride, and there are no sorts of leaks or anything.


TIP: Select a location with an ample amount of room for you to spin the bike around even at high speeds.

Step 6: Cleaning up

After all that work, you want your motorcycle to be ready for a spin. Use a high-pressure water hose to wipe out any trace of fluid that may have been left on the body.


Only a smoothly operating braking system is not sufficient; a shiny outlook is also needed to make a good impression on people and have that extra boost of self-esteem!

Safety Comes First!


You must keep it noted that brake fluid is a very harsh and toxic chemical that can have a negative impact on your health. So certainly, you have to deal with it with extra care and caution.


Similar to a lab, you will need to put on safety rubber gloves to protect yourself from any spillages. Safety goggles are worth to be mentioned to save your sight from the splatter of poison.

Conclusion

We would like to conclude by repeating that bleeding brakes is not the toughest job out there; you just have to remain patient and maintain a sharp sight at the setup.

We hope you are free of the confusion of how to bleed motorcycle brakes and can take on the job with ease using the tips and tricks we have provided you with.
