Anti-lock braking system (ABS) (Mondeo 2)

The anti-lock braking system consists of a conventional braking system with diagonally divided brake circuits and a control unit. The control unit includes a hydraulic module, a compressor, an ABS module with an integrated relay and two pressure-sensitive pressure-reducing valves.

The signals required for ABS operation come from sensors on four wheels. The ABS module compares these signals with the limit values stored in its memory. If one or more wheels lock during braking, the module activates the corresponding valves and the braking force applied to the pad in the corresponding cylinder is reduced.

Once the wheels are unlocked, the ABS module activates the valves and the pressure in the brake cylinder increases, which again causes the wheels to lock.

This process is repeated several times per second depending on the road surface conditions and the duration of braking. At speeds below 5 km/h, ABS operation stops.
