Vehicles without ABS are equipped with brake
pressure reduction valves for the rear wheel
brakes. They are located in the corresponding
brake circuits at the brake master cylinder.
Vehicles with ABS do not need brake pressure
reduction valves because they are equipped with
electronic brake distribution (EBD).
The handbrake is cable operated on the rear
brakes.
On vehicles with a petrol engine the necessary
vacuum for the brake booster is generated by the
intake manifold.
On vehicles with a diesel engine, a vacuum pump
driven by the engine provides the necessary
vacuum for the brake booster.

206-054 Parking Brake and Actuation 206-05-4
DESCRIPTION AND OPERATION
Layout
The handbrake cable mechanism consists of three
sections: the front handbrake cable, the two
handbrake cables underneath the vehicle and the
two rear handbrake cables leading to the brakes.
The front handbrake cable is connected to the
handbrake lever via a threaded piece and a nut.
This nut is used to adjust the handbrake cable.
The two handbrake cables underneath the vehicle are both connected via a threaded piece and a nut
to the equaliser and therefore the front handbrake
cable. They are connected to the rear handbrake
cables via a sleeve connection.
The rear handbrake cables in turn link into the lever
mechanism of the rear brakes.
Function
When the handbrake lever is operated, the front
handbrake cable acts via the equaliser onto the
two handbrake cables underneath the vehicle. Via
the sleeve connection pieces these then act onto
the rear handbrake cables and, via the lever
mechanism, onto the brake.
