5-6 BRAKES
MASTER CYLINDER ASSEMBLY
GENERAL DESCRIPTION
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 (front wheel brakes for vehicle with ABS).
Also, the hydraulic pressure produced in the secondary chamber (“b”) acts on the front wheel brakes (rear wheel
brakes for vehicle with ABS).
CAUTION:
Replace all components included in repair kits to service this master cylinder. Lubricate rubber parts
with clean, fresh brake fluid to ease assembly. Do no use lubricated shop air on brake parts as dam-
age to rubber components may result. If any hydraulic component is removed or brake line discon-
nected, bleed the brake system. The torque values specified are for dry, unlubricated fasteners.
