What is Brake Bleeding?

Before we dive into the details of how to bleed brakes on a dirt bike, let’s first understand what brake bleeding is. Brake bleeding is a process of removing air bubbles that may have entered the brake lines, which can cause the brakes to become spongy or fail entirely. Bleeding the brakes on your dirt bike is essential to ensure proper functioning of the brakes.

Things You Will Need

Before you start bleeding your dirt bike’s brakes, make sure you have the following tools:

  • Brake fluid
  • A wrench
  • A small clear tube
  • A clean cloth

Step-by-Step Guide on How to Bleed Brakes on a Dirt Bike

Now that you have all the necessary tools, let’s dive into the step-by-step guide on how to bleed brakes on a dirt bike.

Step 1: Locate the Brake Bleeder Valve

The first step in bleeding your dirt bike’s brakes is to locate the brake bleeder valve. The brake bleeder valve is usually located on the brake caliper. It is a small valve with a rubber cap that is screwed into the top of the valve.

Step 2: Prepare Your Dirt Bike

Before you start bleeding the brakes, make sure your dirt bike is level and the brake fluid reservoir is full. It’s also essential to ensure that your dirt bike’s brake pads are in good condition.

Step 3: Attach the Clear Tube

Take the clear tube and attach it to the bleeder valve on the brake caliper. Make sure the other end of the tube is submerged in a container filled with brake fluid.

Step 4: Loosen the Bleeder Valve

Using a wrench, loosen the bleeder valve on the brake caliper. You should see brake fluid and air bubbles coming out of the tube.

Step 5: Pump the Brake Lever

Next, pump the brake lever a few times and hold it down. This will force the brake fluid down the brake lines, pushing any air bubbles out of the system.

Step 6: Tighten the Bleeder Valve

While holding down the brake lever, tighten the bleeder valve with the wrench. Make sure you do not release the brake lever until the valve is fully tightened.

Step 7: Check the Brake Fluid Level

Check the brake fluid level in the reservoir and top it off if necessary.

Step 8: Repeat the Process

Repeat the process until there are no more air bubbles coming out of the clear tube. Make sure to check the brake fluid level after every few pumps of the brake lever.

Step 9: Test the Brakes

Once you have bled the brakes, test them by squeezing the brake lever. The lever should feel firm, and the brakes should respond quickly.
