Front Disc Brake

Front Disc Brake
The front disc brake system includes the brake caliper, the disc brake 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 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 disc brake calipers and transferred to the brake pads. 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.
