Safety First When working on the brakes
Always put safety first when working on the brakes. Working on your brakes without safety glasses and a face mask can easily cause you to get brake fluid in your eyes.
Cleanliness is critical when working on the brakes.
Use brake fluid recommended by the manufacturer and from a new, previously unopened container.
Do not reuse brake fluid that has already been through the system, no matter how clean it appears.
Since brake fluid is hygroscopic, it absorbs airborne moisture, so replacing it periodically is recommended.

What is the best way to bleed the front brake on dirt?
Bleeding the front brake is used to remove air from the brake system. The process allows the brake to work properly and prevents the brake from locking up.
Bleeding the front brake on a dirt bike is similar to bleeding the rear brake.
It is important to ensure the motorcycle is clean before removing the master cylinder reservoir cap or loosening a bleeder.
You should remove the seat, gas tank, or subframe from dirt bikes with remote reservoirs attached to it via a hose to gain access to the reservoir. It also visually inspects seldom seen hoses, cables, and wires for chaffing.
Bleeding the brake system involves flushing fluid through the system until it reaches a certain level.
It is best to use a brake flush or bleeding process to bleed front brakes on dirt.
It is important to monitor the reservoir level and stop when it falls between the "Min" and "Max" marks.
Bleed brake fluid using the "Min" and "Max" marks on the reservoir.
Clean reservoir and gasket/diaphragm before bleeding brake fluid.
Install a bleeder cap to prevent dirt from being packed into the bleeder in the future.
How To Bleed A Dirt Bike's Front Brake
Bleeding the brakes on a dirt bike can help restore performance.
Keeping the brake fluid level high while bleeding them is important to avoid introducing air into the system.
If you are having trouble getting brake fluid out of the bleeder - or if you find no pressure at the lever with the bleeder closed, letting the bike sit overnight with the bleeder(s) closed often helps. This allows you to continue bleeding the brakes until you get the desired pressure.
To bleed a dirt bike's front brake, first open the bleeder on the caliper.
Tap the hammer gently against the caliper to dislodge any air or fluid.
Bleed brake fluid until it reaches the "Min" and "Max" marks on the reservoir.
Ensure that all parts of the bike are clean before reinstalling the brakes.
Rinse area of master cylinder and caliper
Use compressed air to dry everything.
Install a bleeder cap
How To Bleed the Rear Brake On A Dirt Bike
Bleeding the rear brake is similar to bleeding the front brake - it's important to ensure the motorcycle is clean before beginning.
On dirt bikes with a remote reservoir attached to the rear brake master cylinder, it's best to remove the seat, gas tank, or subframe for easier access.
You can drain the reservoir of your working system as long as the master cylinder still has fluid in the hose.
Re-fill the reservoir and repeat steps of removing fluid until all of it has been removed.
First, tap the rear brake caliper gently with a plastic hammer, working up from the bottom, directing "Hits" upwards.
Suppose no brake fluid exits from the brake bleeder within a few seconds of the bleeder being open. Using a stiff piece of wire, a pick, brake cleaner, and compressed air remove any obstruction in the orifice in the bleeder.
When the reservoir is full of brake fluid and the line is flushed, close Bleeders when the level falls between "Min" and "Max." Ensure reservoir cover and gasket/diaphragm are clean.
Clean with brake clean followed by compressed air drying, then reinstall the cover, screws, gasket, and cap on integral reservoirs.

How To Reverse Bleed Dirt Bike Brakes
You'll need 2 syringes to do this.
To reverse bleed your dirt bike brakes, you'll need 2 syringes: one to pump brake fluid into the system and one to suck it back out. Connect the hoses from each syringe to the brake calipers (or lever), ensuring that the hoses are not twisted.
Pump brake fluid into the system after filling the syringe with it. Once all of the air is expelled, disconnect the hose from the caliper and attach it to the syringe. Suck on the hose to draw the brake fluid back into the syringe. Disconnect the hose and dispose of the brake fluid properly when you're finished.
Attach the hose to the drainage nut after filling the syringe with new brake fluid.
You will need a few supplies to reverse bleed the dirt bike brakes. Add new brake fluid to your syringe and connect the hose to the drainage nut. Let the brake pedal rest on the ground for a few seconds.
By opening the caliper's bleeder valve, you can release the brake pedal. Close the valve quickly after letting go of it. Replacing the cap is the last step once all of the air in the brake fluid reservoir has been removed.
With your wrench, loosen the drainage nut to drain the brake fluid slowly. When the small amount of fluid is in, tighten up the nut and check the main reservoir that it's not full. Repeat this process until you've put in about 1/4 of a gallon.
This is the most important step, so make sure you're ready to go before starting. You need to bleed the brake lever and the caliper. You need to get the air out of the system so that all of your fluid goes into the lines and not just down around your brake pads.
With the bike on a stand and the front wheel off, loosen the bleeder screw with your wrench. Using pliers or having someone hold it for you is a good idea if the bleeder screw is tight.
Once it's loose, push down on the brake lever with your hand and tighten the bleed screw again. Your system will be forced to breathe.
Continually repeat this step until the bubbles in the bleeder screw have stopped coming out, and the brake lever is firm. You might need to loosen up the bleed screw and press down on the brake lever again if there are still bubbles in the system. Tighten it back up and keep repeating until you have no more bubbles.
Can You Use Car Brake Fluid on A Dirt Bike?
You can use car brake fluid on your dirt bike, but I'd recommend against it.
Most cars use Dot 3 brake fluid, while most dirt bikes use Dot 5 or Dot 4.

After bleeding your brakes, clean the caliper and reservoir area to get rid of any spilled fluid.
Lube the main reservoir screws to make them easier to remove next time.
How do you bleed a dirt bike with empty brakes?
To bleed a dirt bike with empty brakes, you'll need the following tools: DOT 4 brake fluid, a wrench, and a reservoir.
Pump the brake lever twice to fill the reservoir with fluid and loosen the nipple with the wrench.
Let go of the brake lever to allow fluid to drain out and top off the brake fluid again as needed.
Repeat until new brake fluid seeps through - make sure you constantly top off the fluid during bleeding, so air doesn't get into your lines!
Bleeding brakes with an empty reservoir is a way to get fresh brake fluid into the system.
To bleed brakes, depress the pedal to the floor and open the bleed nipple on the master cylinder.
To catch any liquid leaking out of the system, use a clean container.
