5A-2 BRAKES PIPE/HOSE/MASTER CYLINDER

Master Cylinder Assembly

The master cylinder has two pistons and three piston cups. Its hydraulic pressure is produced in the primary ("a"
in the figure below) and secondary ("b") chambers. The hydraulic pressure produced in the primary chamber
("a") acts on the rear wheel brakes.
Also, the hydraulic pressure produced in the secondary chamber ("b") acts on the front wheel brakes.
WARNING:
Brake master cylinder cannot be disassembled. When anything faulty is found in it, it must be
replaced as an assembly.
CAUTION:
Brake master cylinder cannot be disassembled in principle. Should primary piston have come off
from cylinder while dismounting or handling it, wash it in the same specified fluid as that in reservoir
and place it back in cylinder.
