Valve Assembly

The valve assembly provides brake fluid pressure modulation for each of the individual wheel circuits, as required, during an ABS event. During an ABS event, the valve assembly can maintain or reduce brake fluid pressure that is applied by the master cylinder. The valve assembly cannot increase pressure beyond what is applied by the master cylinder. The valve assembly contains a motor-driven pump, ABS inlet and outlet valves. With exception of the Electronic Brake and Traction Control Module (EBTCM), the valve assembly is not serviceable and should never be disassembled.

The valve assembly is an addition to the four-circuit diagonally-split hydraulic system found on vehicles with ABS.
