Brake Master Cylinder: Description and Operation
Features/Construction/Operation
Master Cylinder
1. Construction
A tandem master cylinder is used to improve the safety of the braking system. In addition, center valves are used to match the anti-lock brake
system operation.
The master cylinder has one reservoir tank which is connected to the cylinder sections by two small holes. It has two pistons~primary and
secondary, which are crisscross connected with the calipers so that the fluid pressure works separately on each system (front right wheel & rear left
wheel, and front left wheel & rear right wheel). A stop bolt for controlling movement of the primary piston is provided at the side of the master
cylinder body. A reed switch for detecting the brake fluid volume is also provided in the cap of the reservoir tank.
2. Operation
When the brake pedal is depressed, the secondary piston is pushed through the brake booster and the center valve B is closed so that fluid pressure
is generated on the secondary side. At the same time, the primary piston is pushed by the secondary fluid pressure and the center valve A is closed
so that braking fluid pressure is generated both on the primary and secondary sides.
When the brake pedal is released, the primary and secondary pistons are returned to the original position by the brake fluid pressure and piston
spring.
