A traction/stability control supply solenoid valve and an isolation solenoid valve for each brake circuit. The solenoid valves are not engaged during normal system operation. When the ABS, the traction control, or the stability control operation is required the Electronic Brake Control Module (EBCM) turns the required solenoid ON.
