NSX V6-3.0L DOHC (1991)
Brake Master Cylinder: Description and Operation
1. Construction
-
A tandem master cylinder with center valves are 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 diagonally 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 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.
