ABS / DSC hydraulic unit
Modulates individual wheel brake pressure for control functions.
In the engine bay or a protected brake-system mounting location.
Valves and a pump adjust hydraulic pressure using wheel and vehicle-motion signals.
A fast set of taps managing each wheel’s braking.
Warning lights can be triggered by sensors, supply voltage or wiring as well as the unit.
Pads and discs are measured wear items. Driving, environment and regenerative braking change wear; use the actual inspection limits.
Ordinary friction service differs greatly from carbon-ceramic replacement or hydraulic-controller work; obtain a vehicle-specific quote.
BMW calls its stability-control system DSC; ABS is one of the braking functions it incorporates.
BMW models with hydraulic friction brakes; performance equipment and parking-brake design vary.
