Brake Pedal Assy: Description and Operation
SYSTEM DESIGN
This system is designed to permit a full stroke of the brake master cylinder when the brake pedal is fully depressed. A brake pedal clearance
adjustment is not required.
NOTE: If pedal travel seems restricted, check for obstructions.
FLUID RETURN
To release the brakes, fluid must flow back to the brake master cylinder through a return port when pedal pressure is released. To be sure the brake
master cylinder piston moves back far enough to expose the return port, free play is built into the brake pedal linkage. This prevents the brake
master cylinder piston from becoming trapped in a partially released position. If a problem is suspected, the brake pedal push rod and brake pedal
should be checked to make sure they are not binding. Pedal free play is not always perceptible in dash-mounted booster systems, because the
operating clearance for the brake master cylinder piston is adjusted at the booster push rod, rather than the pedal linkage.
