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.
