Proportioning valves balance front to rear braking
by controlling the brake fluid hydraulic pressure to
the rear brakes. Under light pedal application, the
proportioning valve allows normal fluid flow to the
rear brakes. Under higher pedal effort, the valve
reduces fluid pressure to the rear brakes.
The non-antilock master cylinder is a four-outlet
design with two screw-in proportioning valves
attached directly to the master cylinder housing (Fig.
3). One proportioning valve controls each rear brake.
BRAKE TUBES AND HOSES
The purpose of the brake tubes and flex hoses is to
transfer the pressurized brake fluid developed by the
master cylinder to the brakes at each wheel of the
vehicle. The flex hoses connect the chassis brake
tubes, which are mounted to the vehicle's underbody,
to the brake at each wheel, allowing for movement of
the vehicle's suspension. The brake tubes are steel
with a corrosion-resistant nylon coating applied to
the external surfaces. The flex hoses are made of
reinforced rubber.
DISC BRAKES (FRONT)
The front disc brakes consist of the following com-
ponents (Fig. 4):
²Brake caliper - single-piston, floating type
²Brake shoes and linings
²Brake rotorWhen the brakes are applied, fluid pressure is sent
to each brake caliper. The pressure at the caliper is
exerted equally against the caliper piston. The pres-
sure applied to the piston is transmitted directly to
the inboard brake shoe. This forces the shoe lining
against the inner surface of the brake rotor. At the
same time, fluid pressure within the caliper piston
bore forces the caliper to slide inward on its guide
pins. This action brings the outboard shoe lining into
contact with the outer surface of the brake rotor.
This pressure on both sides of the brake rotor causes
friction, bringing the vehicle to a stop.
BRAKE CALIPER
The caliper is a one-piece casting with the inboard
side containing a single piston cylinder bore (Fig. 5).
The front disc brake caliper piston, is manufac-
tured from a phenolic compound. The outside diame-
ter of the caliper piston is 54 mm.
A square-cut rubber piston seal is located in a
machined groove in the caliper cylinder bore. This
provides a hydraulic seal between the piston and the
cylinder wall (Fig. 6). The piston seal is designed to
pull the piston back into the bore of the caliper when
the brake pedal is released. This maintains the
proper brake shoe-to-rotor clearance.
A rubber dust boot is installed in the cylinder bore
opening and in a groove in the piston (Fig. 6). This
prevents contamination in the bore area.
The caliper is mounted to the steering knuckle
using bushings, sleeves and two guide pin bolts (Fig.
5). The guide pin bolts thread directly into bosses on
the steering knuckle.
Two machined abutments on the steering knuckle
position the caliper. The guide pin bolts, sleeves, and
bushings control the side-to-side movement of the
caliper. All of the front brake force generated during
braking of the vehicle is taken up directly by the
steering knuckles of the vehicle.
BRAKE SHOES AND LININGS
There are two brake shoes mounted to each caliper,
one inboard and one outboard (Fig. 5). When brake
shoes are replaced, only brake shoes meeting the
original equipment manufacturer (OEM) formulation
(such as Mopartreplacement parts) should be used.
As front disc brake shoe linings wear, master cyl-
inder reservoir brake fluid level will drop. Fluid level
should be checked after replacing shoes.
Front disc brakes are equipped with an audible
wear indicator on the outboard brake pad (Fig. 5).
This sensor emits a sound when the brake lining
may need inspection or replacement.
