System Component Description

WARNING: This page is about a different car, the 2018 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.

The measurement used to identify the brake system indicates the minimum wheel size that must be installed. For example: If a 16 inch brake system is identified, the smallest wheel that can be installed is a 16 inch wheel.

The disc brake system consists of the following components:

Disc Brake Pads: Applies mechanical output force from the hydraulic brake calipers to friction surfaces of brake rotors.

Disc Brake Rotors: Uses mechanical output force applied to friction surfaces from the disc brake pads to slow speed of tire and wheel assembly rotation.

Disc Brake Pad Hardware: Secures disc brake pads firmly in proper relationship to the hydraulic brake calipers. Enables a sliding motion of brake pads when mechanical output force is applied.

Disc Brake Caliper Hardware: Provides mounting for hydraulic brake caliper and secures the caliper firmly in proper relationship to caliper bracket. Enables a sliding motion of the brake caliper to the brake pads when mechanical output force is applied.
