How to bleed front brakes on a motorcycle?
In this video you will learn how to bleed front brakes on a motorcycle. The process is the same on motorcycle rear brake bleeding. This is the very simple process of removing air that has entered the brake system and filling the entire system, from the master cylinder to the brake calipers, with brake fluid. There are many ways to do this process.
What does it mean when you bleed brake fluid?
As the brake lever is being actuated, a series of air bubbles will be seen coming from the end of the bleed bottle’s tube, below the fluid level. These bubbles are the air within the system being forced out by the new brake fluid. When the mechanic is satisfied that the brake system is full of fluid, the final bleeding phase can be done.
What can I use to clean brake fluid off my bike?
Use water to clean up any traces of brake fluid on the bike and the work area. Try to use tools that guarantee success when bleeding motorcycle brakes. This includes pressurized brake bleeders and vacuum bleeding kits. Watch out for brake fluid as it can easily ruin the bike’s paint job.

The other end of the tubing should be placed into a catch bottle. To begin the bleeding process, squeeze the brake lever (front) or push the pedal down (rear), then open the bleed valve ¼ – ½ turn. A mixture of air and brake fluid should exit from the bleeder valve and be visible in the clear tube. Close the bleed valve.

The process is fairly straightforward on a bike that has had fluid in it: Pump up the brake to achieve pressure, open the bleeder without releasing the brake to expel air, close the bleeder, allow the pedal/lever to return to its resting position. Repeat until the brakes have good feel. Here’s the problem: folks get nervous about it.

Why do I keep losing brake fluid on my motorcycle?
Remember, brakes are a sealed system: If you are losing brake fluid regularly, something is wrong and needs more attention than a simple bleeding job. Similarly, since the fluid level drops as the pads wear, don’t just add fluid helter-skelter.
