8. The master cylinder fluid level will drop as the brakes are bled. Periodically check and fill the
master cylinder during this procedure. Do not allow the fluid level in the master cylinder to drop
too low as this will allow air into the brake lines.
9. Attach a clear hose to the bleeder valve on the brake cylinder that is to be bled. Route the hose
into a clear container for waste brake fluid.
10. Pump the brake pedal a few times and then press
and hold light pressure to the brake pedal.

to its released position.
Note: Check and fill the master cylinder
14. Repeat the above steps until you are sure that all of the air is expelled from the brake line. Any
air bubbles that can be seen in the clear hose attached to the bleeder is an indication that there
is still air in the brake lines.
15. Repeat this process with each of the other wheels.
Note: When finished, top off the master cylinder with fluid. See

frequently during the bleeding process.
Do not allow the fluid level in the
master cylinder to drop low enough to allow air to enter the brake
lines. If air enters the brake lines during the bleeding process, then
you will have to start again from the beginning.
Always use brake fluid from a new sealed container. Never reuse any
brake fluid that has been removed from the brake system. Use of
contaminated brake fluid will degrade the braking performance and
may cause property damage or severe bodily injury.
