Rear Disc Brake

WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

The rear disc brake system includes the brake caliper, the disc brake pads, and the brake disc. The brake caliper is a single piston floating design. The brake caliper is mounted to the rear knuckle by the caliper guide bolts. The brake caliper slides, or floats, on the caliper guide pins. The brake disc is a cast, non-ventilated type disc. When mechanical force is applied by the driver to the brake pedal, the force is converted into hydraulic pressure by the master cylinder. The hydraulic force is directed to the brake calipers and transferred to the brake pads. The brake pads are then forced against the brake friction surfaces by the brake caliper pistons. The friction of the brake pads on the brake disc causes the slowing of wheel rotation and the vehicle.
