Front Disc Brake

The front brake disc system includes the brake caliper, the brake disc pads, the anchor plate and the brake disc. The brake caliper is a dual piston floating design. The brake caliper is mounted to the anchor plate by the caliper guide bolts. The brake caliper slides, or floats, on the caliper guide bolts. The brake disc is a cast, ventilated type rotor. 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. The brake pads are then forced against the brake disc 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.
