Brake Master Cylinder: Description and Operation
Brake Master Cylinder
The brake master cylinder is a dual-piston type assisted by a power brake booster.
The following conditions are considered normal and not indications that the brake master cylinder is in need of repair or replacement:
^ Low brake fluid level detected without signs of leakage. This condition is caused by displacement of brake fluid from the brake master cylinder
reservoir into the front disc brake calipers and/or the rear disc brake calipers to compensate for normal brake wear. Add brake fluid as needed.
^ A momentary or slight squirt of brake fluid from the brake master cylinder reservoir upon application of the brake pedal.
^ A trace of brake fluid found on the outside of the power brake booster below the brake master cylinder mounting flange. This condition results from
the lubricating action of the brake master cylinder wiping seal.
