Brake Master Cylinder: Testing and Inspection
Inspection
When in the brake master cylinder area, check the brake lines and brake master cylinder mounting. The brake lines and attaching nuts must be tight. The
brake line fittings must not show any signs of leakage. Tighten the brake lines at the brake master cylinder to 15-20 Nm (11-15 ft lb).
The following conditions are considered normal and are not indications that the brake master cylinder is in need of service:
^
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 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. This condition is caused
by brake fluid displacement through the brake master cylinder reservoir compensating port as the brake master cylinder pistons move forward in
the bore when the brakes are applied.
^
Slight turbulence in the brake fluid when the brake pedal is released. Turbulence occurs as brake fluid returns to the brake master cylinder after
releasing the brakes.
^
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 master cylinder wiping seal.
