Tools And Materials Needed

  • Brake bleeder wrench
  • Brake fluid
  • Clear plastic tubing
  • Bleeder catch bottle
  • Clean cloth

To bleed the rear brakes on a dirt bike, you will need a few essential tools and materials. First, locate a brake bleeder wrench, which is crucial for loosening and tightening the brake bleeder valve. Next, ensure you have an adequate supply of brake fluid, as this will be needed to refill the brake system during the bleeding process.

You will also need clear plastic tubing, which will connect to the brake bleeder valve and allow the old brake fluid to be safely drained out. Make sure to have a bleeder catch bottle ready to collect the old fluid. Lastly, keep a clean cloth nearby to wipe any spilled brake fluid and ensure a clean working area.

Preparing For The Process

Elevating the dirt bike is an important step in preparing to bleed rear brakes. By placing the bike on a stand or securely propping it up, you will have easy access to the brake caliper and brake fluid reservoir. Ensure that the bike is stable and balanced before proceeding.

Next, cleaning the surrounding area is crucial to prevent any dirt or debris from contaminating the brake system. Use a clean cloth or brake cleaner to wipe down the brake caliper, reservoir, and surrounding components.

Gathering the necessary tools and materials beforehand will streamline the process. You will need a wrench or socket to loosen the brake caliper bolts, a brake bleeding kit or tubing to connect to the bleeder valve, and an appropriate brake fluid for your bike’s specifications. Additionally, it’s helpful to have a catch container to collect the old brake fluid.

How to Bleed Rear Brakes on a Dirt Bike: 7 Steps Guide

Step 1: Removing The Reservoir Cap

To bleed the rear brakes on a dirt bike, the first step is to remove the reservoir cap. Start by locating the rear brake reservoir on your bike. Once located, use a brake bleeder wrench to carefully remove the cap. This will give you access to the fluid inside the reservoir. Before proceeding, it’s important to check the fluid level to ensure it is at the appropriate level.

Avoid any spills or contact with the brake fluid as it is corrosive. To avoid any accidents, it is recommended to wear gloves and protective eyewear. Once the cap is safely removed and the fluid level is checked, you can move on to the next step of bleeding the rear brakes.

Step 2: Preparing The Bleeder Valve

Before bleeding the rear brakes on your dirt bike, it’s important to locate the bleeder valve on the rear brake caliper. Use a clean cloth to clean the valve, ensuring there is no dirt or debris that could cause a blockage. Once clean, you can begin to loosen the valve slightly.

Step 3: Attaching The Plastic Tubing

Step 3 of bleeding rear brakes on a dirt bike involves attaching the plastic tubing. Begin by cutting a piece of clear plastic tubing to use for the process. Once you have the tubing ready, connect one end to the bleeder valve on the caliper. Make sure it fits securely to avoid any leaks. The other end of the tubing should be placed into a bleeder catch bottle to collect the brake fluid.

By attaching the plastic tubing correctly, you create a pathway for the brake fluid to flow out of the system. This helps in removing air bubbles and ensures a proper bleed. Take care to follow the proper steps and secure all connections to achieve effective results. Now you’re ready to move on to the next step in bleeding the rear brakes of your dirt bike.

Step 4: Pumping The Brake Pedal

When bleeding the rear brakes on a dirt bike, it is important to follow the proper steps to ensure optimal performance. After completing the previous steps, it is time to move on to step 4: Pumping the Brake Pedal.

Sitting on the dirt bike and finding a comfortable position, place your foot on the brake pedal. Apply steady pressure on the pedal, but avoid stomping on it forcefully. Slowly release the pressure on the pedal and repeat this process several times.

By pumping the brake pedal in this manner, you are allowing any air bubbles or contaminants in the brake fluid to work their way out of the system. This will ensure that your dirt bike’s rear brakes function smoothly and effectively.

Step 5: Opening And Closing The Bleeder Valve

In this step of the brake bleeding process, we will focus on opening and closing the bleeder valve to release air and fluid. Begin by using a wrench to loosen the bleeder valve, being careful not to fully open it at this stage. Once the valve is slightly open, have a friend apply gentle pressure to the brake pedal while you observe the fluid coming out of the valve. It is important to monitor the fluid as it exits the valve because you are looking for any air bubbles.

If air bubbles are present, it indicates that there is still air in the brake system. As your friend maintains pressure on the pedal, tighten the bleeder valve again to close it. Repeat this process until no air bubbles are visible in the fluid exiting the valve. This ensures that all air is properly bled from the rear brakes of your dirt bike.

Step 6: Checking The Fluid Level

To bleed the rear brakes on a dirt bike, it is essential to check the fluid level. Start by refilling the reservoir with fresh brake fluid that meets the manufacturer’s specifications. This ensures that the brakes will function properly and provide adequate stopping power. Next, check that the fluid level is within the recommended range. It is crucial to maintain the correct fluid level to guarantee optimal brake performance.

Finally, tighten the reservoir cap securely to prevent any leakage or air from entering the brake system. Following these steps will help ensure a successful and safe bleeding process for the rear brakes on your dirt bike.

Step 7: Testing The Brakes

After successfully bleeding the rear brakes on your dirt bike, the next step is to test the brakes to ensure they are functioning properly. Start by **pumping the brake pedal** several times to restore pressure in the system. This will help eliminate any air bubbles that may still be present. While pumping, pay close attention for any **leaks or abnormalities** in the brake lines or connections. It is crucial to address any issues before proceeding.

Once you have completed the pumping process, it’s time to take a **brief test ride** to evaluate the brake functionality. Begin by slowly applying pressure to the brake lever and ensure that the rear brake engages smoothly and firmly. Test it at various speeds and in different scenarios to verify its performance under different conditions. If everything feels and looks good, congratulations! You have successfully bled and tested the rear brakes on your dirt bike.
