Disc Brake System: Description and Operation

WARNING: Brake fluid contains polyglycol ethers and polyglycols. avoid contact with eyes. Wash hands thoroughly after handling. if brake fluid contacts eyes, flush eyes with running water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately.

NOTE: Brake friction materials inherently generate noise and heat to dissipate energy. As a result, occasional squeal is possible and it is aggravated by severe environmental conditions such as cold, heat, rain, snow, salt, mud and other conditions.

FRONT
Front disc brakes have the following features:
- Pin slider-type caliper assemblies.
- Bolt on anchor bracket attached to the front wheel spindle with two bolts.
- 291 mm (11.4 inch) full cast composite front disc brake rotors.
- The disc brake caliper has a steel caliper piston with a piston seal and a press-in type dust boot.
- The disc brake caliper is mounted to two slide pins which, are lubricated and assembled in the front disc brake caliper anchor plate.

REAR
The rear disc brakes have the following features:
- a 285 mm (11.2 inch), drum-in-hat style, solid, full cast, rear disc brake rotor.
- The rear disc brake rotor is mounted on the axle flange.
- hydraulically activated rear disc brake calipers.
- a pin slider-type rear disc brake caliper assembly
- rear disc brake caliper has a steel rear disc brake piston with a seal and a press-in type dust boot
- The mechanically (cable) operated parking brake mechanisms are not part of the calipers.
^ A rear wheel disc brake adapter that:
- transmits braking torque from the inner and outer rear brake shoes and linings to the rear axle housing.
- provides a mounting for the parking brake assembly.
