Replacing of brake pads on vehicles with electromechanical parking brake


The electromechanical parkingbrake is integrated in the rear wheel brake caliper. The electrical signal is transfered to a mechanical movement by a step motor and a multistage gear device to press the brakepads against the brake disc. When service is performed on the rear wheel brakes it is necessary to open the parkingbrake and release the brakepads by moveing the brake pistons backwards with a diagnostic instrument. After service is performed the parking brake must be applyed with a diagnostic instrument, and the brakepads new position is automatically stored.

Observe:

It is necessary to reset the brake pistons when following operation is performed:

After service is performed and the parking brake is adjusted the fault code: 1087 basic setting not performed is stored in the fault memory. The fault code 473 Electromechanical parking brake control unit; basic setting not performed is also stored in the ABS control unit. In connection to this must a basic setting of the brake system be performed.
