Waste heat from an air compressor warms a liquid tank to heat fluid for sensor cleaning and defrosting while reducing redundant vehicle subsystems.
A hollow cylindrical holder replaces glued magnetic mounting on the motor shaft, improving rotation angle sensing and simplifying brake drive assembly.
Pressure feedback and a shutoff time window stop continuous vacuum pump motor running when pressure no longer changes, cutting wear and energy waste.
Axial inlet flow in the brake pump housing opens the outlet valve against closing force, cutting deflection losses and simplifying pressure release.
