Front Disc Brakes

DESCRIPTION - DISC BRAKES (FRONT)





The front disc brakes consist of the following components (Fig. 5):
^ Brake caliper - single-piston, floating type
^ Brake shoes and linings
^ Brake rotor





The caliper is a one-piece casting with the inboard side containing a single piston cylinder bore (Fig. 6).

The front disc brake caliper piston, is manufactured from a phenolic compound. The outside diameter of the caliper piston is 54 mm.

The caliper is mounted to the steering knuckle using bushings, sleeves and two guide pin bolts (Fig. 6). 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.

There are two brake shoes mounted to each caliper, one inboard and one outboard (Fig. 6). When brake shoes are replaced, only brake shoes meeting the Original Equipment Manufacturer (OEM) formulation (such as Mopar replacement parts) should be used.

The brake shoe linings contact the brake rotor. Each front brake rotor is vented to help cool it during and after brake applications. It is mounted on the studs of the front wheel bearing hub.
