5.1.2 MASTER CYLINDER
The master cylinder is installed on the bracket of the brake pedal unit as shown in Fig. 5.3.
Built in the master cylinder are a check valve, spring and piston. They are kept in position by a snap
ring.
The primary and secondary cups installed on the piston slide inside the cylinder when brake pedal is
operated.
The check valve is operated so that the proper pressure remains in the wheel cylinder and brake pipe.
This pressure keeps pushing the piston cup of each wheel cylinder so as to prevent oil leakage and also
prevent vapor locking from occurring.
