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.

4C-2 POWER BOOSTER
DESCRIPTION AND OPERATION
GENERAL DESCRIPTION
The power booster is a double-diaphragm, vacuum-sus
pended unit. In normal operating mode, with the service
brakes in the release position, a vacuum-suspended
booster operates with a vacuum on both sides of its
diaphragm. When the brakes are applied, air at
atmospheric pressure is admitted to one side of the
diaphragm to provide the power assist.When the brakes are released, atmospheric air is shut
off from that side of the diaphragm. The air is then
drawn from the booster through the vacuum check
valve by the vacuum source.
Important: If any hydraulic component is removed or
disconnected, it may be necessary to bleed all or part
of the brake system. Refer to Section 4F, Antilock
Brake System and Traction Control System.
