Rear Disc Brake: Overview

Rear Disc Brake

OVERVIEW
The caliper is mounted within a fixed carrier that is secured to the rear wheel knuckle with two bolts. The brake calipers on the supercharged vehicle are painted and also include a logo badge, which must be removed in order to renew the brake pads.
Each inboard brake pad is installed with a wire type anti-rattle spring.
Also incorporated into each rear brake caliper carrier is the parking brake mechanism. For additional information refer to 206-05 Parking Brake and Actuation.
After any work on the rear brakes, the parking brake must be re-calibrated. For additional information refer to 206-05 Parking Brake and Actuation.
