4B-2 MASTER CYLINDER
DESCRIPTION AND OPERATION
GENERAL DESCRIPTION
The master cylinder is designed for use in a parallel
split system. One front and one parallel to rear brakes
are served by the primary piston. The opposite front
and rear brakes are served by the secondary piston.
The master cylinder incorporates the functions of the
standard dual master cylinder, plus a low fluid level
indicator. The brake fluid level switch is attached under
the body of the plastic brake master cylinder reservoir.
Notice: Do not use lubricated shop air on the brake
parts, because oil will damage the rubber components.Important:•Replace all the components included in the repair
kits used to service the master cylinder.
Lubricate the rubber parts with clean brake fluid to
ease assembly.
If any hydraulic component is removed or discon-
nected, it may be necessary to bleed all or part of
the brake system. Refer to Section 4F, Antilock
Brake System and Traction Control System.
The torque values specified are for dry, unlubricated
fasteners.
Perform all service operations on a clean bench,
free from all traces of mineral oil.
