How Do You Bleed Air From Motorcycle Brakes?

 At Taverner Motorsports, we understand that maintaining your motorcycle’s braking system is crucial for safe and enjoyable riding. One key aspect of brake maintenance is bleeding the brakes, which involves removing air from the brake lines. Air in the brake system can lead to a spongy brake feel and reduced braking efficiency. Here's a step-by-step guide on how to bleed air from motorcycle brakes.

Understanding the Need for Brake Bleeding

Air can enter the brake system during routine maintenance, such as brake pad replacement, or gradually over time, through microscopic gaps in the system. When air is present, it compresses under pressure, unlike brake fluid, leading to decreased braking power.

Tools Required for Brake Bleeding

Before you start, ensure you have the following tools:

A box-end wrench (size varies depending on your motorcycle)
Brake fluid (refer to your motorcycle manual for the correct type)
A brake bleeding kit or a clear tube and a small container
Rags or towels for cleaning up spills
Step-by-Step Guide to Bleeding Motorcycle Brakes

Step 1: Prepare Your Motorcycle

Place your motorcycle in a stable and level position. Ensure the brake fluid reservoir is accessible and clean around the cap to prevent contaminants from entering the system.

Step 2: Locate the Bleeder Valve

The bleeder valve is usually found on the brake calliper. Clean the valve to prevent dirt from entering the brake system.

Step 3: Connect the Bleeding Kit

Attach the tube from your bleeding kit to the bleeder valve, with the other end in a container to catch the old fluid.

Step 4: Refill the Brake Fluid Reservoir

Open the brake fluid reservoir and fill it with the correct fluid. Keep an eye on the level throughout the process to avoid air entering the system.

Step 5: Bleed the Brake

With a partner or solo brake bleeding tool, press the brake lever or pedal to build pressure. While maintaining pressure, open the bleeder valve to allow fluid and air to escape. Close the valve before releasing the brake lever. Repeat this process until no air bubbles are visible in the fluid exiting the system.

Step 6: Check and Test

After bleeding the brakes, check the fluid level and ensure the brake lever or pedal feels firm. Test the brakes in a safe area to confirm proper operation.
