40.1 BRAKES - SERVICE BRAKE AND PARKING BRAKE

The service brake is the system that is designed to slow down the vehicle and bring it to a stop. The service brake is activated everytime you step on the brake pedal and it distributes the braking force hydraulically to the front and rear wheels, 75% front and 25% rear, on average.

The parking brake is the brake that is designed to hold the vehicle. Parking brakes are also referred to as emergency brakes although, in an emergency they would never slow down a vehicle in a safe manner. The parking brake is typically cable operated and applies force to either dedicated brake shoes inside the rear rotor or,through the piston in the caliper. It can be operated by a seperate handle ever, usually located beside the driver’s seat.
