Anti-Lock Braking System (Abs) Repair Information: Notes
The ABS brake system is divided diagonally. The brake booster operates pneumatically via the vacuum brake booster.
Vehicles with ABS do not have a mechanical brake pressure regulator. A specially coordinated software program in the control module determines brake pressure allocation at the rear axle.
NOTE:
ABS malfunctions do not affect the brake system and the booster. The conventional brake system remains operative even without ABS. A change in braking behavior must be anticipated. When the ABS indicator lamp comes on, the rear wheels may lock prematurely when braking!
