18.09.2006 - Ce frein de stationnement électrique offre un surcroît de confort à l’automobiliste (p. ex. pas de levier de frein à main dans l’habitacle, aide au démarrage en côte), mais pour les garages, rend les réparations plus complexes en cas d’intervention sur le système de freinage.

To replace the brake pad or disc, the pistons of the brake caliper need to be retracted electrically. It is  not possible to press the brake caliper pistons back mechanically. If the pistons are forced back, the mechanism inside the caliper will be damaged.

To perform the necessary work on these systems, workshops currently need the diagnostic unit offered by the vehicle manufacturer. This unit allows the pistons to be advanced or retracted. In addition, the brake caliper can be returned to the base position prescribed after completion of any work on the brakes.

During repair work, it is essential to make sure that the (cable) connection between the diagnostic unit and the brake caliper is not interrupted at any time.
