Electric Parking Brakes
The automotive industry is replacing mechanical systems with electronic systems that take up less room in the passenger compartment and require less maintenance and fewer adjustments.
There are two types. Cable-puller EPB parking brakes that use cables that can stretch and require periodic checks and adjustments and caliper-integrated EPB parking brakes that are fastened to the brake caliper and have no cables to adjust.
Today's EPB's have switch on the center console by the shifter or the dash that activates and deactivates the parking brake. The controller monitors different sensors on the CAN (Controller Area Network).
They offer many advantages over manual systems. Integrated automatic computer-controlled features like Hill/Start and Hill/Hold are convenient, especially with vehicles equipped with manual transmissions.
Electric braking systems require a manufacturer-specific procedure to place the system in service or maintenance mode before servicing. The procedure depends on the vehicle. Typically a scan tool is used to place the system in service mode before replacing the brake pads.
