Master Cylinder
1. Construction
A tandem master cylinder with center valves is used to improve braking system safety.
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 sep-
arately 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 on the cap of the reservoir tank.
2. Operation
When the brake pedal is depressed, the secondary piston is pushed through the brake booster and center valve B is
closed so that the fluid pressure is generated on the secondary side. At the same time, the primary piston is pushed by
the secondary fluid pressure and 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 positions by the brake
fluid pressure and piston spring.
