General notes on anti-lock braking system (ABS): Notes
The following variants of ABS are possible:
- ABS
- ABS/EDL
- ABS/EDL with ASR
- ABS/EDL/ASR with electronic stabilization program (ABS/EDL/ASR/ESP)
The ABS brake system is divided diagonally. The servo assist is effected pneumatically, by the vacuum brake servo unit.
Malfunctions on the ABS influence the brake system and servo assistance. A braking behavior change should be checked. When the ABS warning lamp comes on, rear wheels can lock-up when braking!
ABS layout.
Hydraulic unit -a- and control module -b- are one unit and if malfunctions occur they should be replaced (apart from ABS/EDL/ASR/ESP Bosch 5.3).
