Brake systems · Anti-lock brake system · General notes for anti-lock brake system (ABS)

Bosch 8.2 and 9.0

The following configurations are possible on vehicles with the ABS Bosch 8.2 and 9.0:

  • ABS
  • ABS/EDL/TCS/ESP

The ABS brake system is divided diagonally. The servo-assistance is effected pneumatically by the vacuum brake servo unit.

Faults in the ABS do not influence the brake system and servo assistance. The conventional brake system remains functional even without ABS. A change in braking behaviour is to be reckoned with. After the ABS warning lamp comes on, the rear wheels may lock prematurely during braking.

  • 1 Hydraulic unit and control unit
  • 2 Brake booster

ABS layout in right-hand drive vehicle:

  • 1 Brake booster
  • 2 Hydraulic unit and control unit

The hydraulic unit -2- and control unit -1- form one component. Hydraulic pump -3- must not be separated from hydraulic unit.
