Brake Master Cylinder: Description and Operation
Brake Master Cylinder - Operation
OPERATION
When the brake pedal is pressed, the master cylinder primary and secondary pistons apply brake pressure through the chassis brake tubes to each brake
assembly. The brake fluid reservoir supplies the brake hydraulic system with the necessary fluid to operate properly.
The master cylinder's outlet ports supply hydraulic pressure to the Integrated Control Unit (ICU) where it is distributed to the individual wheel brakes.
The master cylinder reservoir cap diaphragm is slit to allow atmospheric pressure to equalize on both sides of the diaphragm.
