Anti-lock Brake System (ABS),
Bosch 5.3
A traction control system (TCS/ASR) is available
as optional equipment for front-wheel-drive
models.
The brake system of the ABS is split diagonally.
The brake servo assistance is provided
pneumatically by a vacuum brake servo unit.
Hydraulic unit -a- and ABS control module -b- form a single unit. The
combination of these two components is termed the hydraulic control
unit.
Sources of malfunctions are reduced as a result of the direct link between
the two components.
CAUTION!
It is not possible to repair the hydraulic control unit. If faulty, it
should be replaced. The bolts which connect the individual components of the
hydraulic control unit must not be loosened.
