ABS Modulator Valve
Mack

The ABS modulator valve is a key component of the anti lock braking system that modulates brake pressure to each wheel to prevent lock up and maintain steering control on slippery surfaces. This hydraulic valve assembly includes integrated solenoids and seals designed for long service life in demanding road conditions. Proper operation ensures rapid and controlled brake pressure adjustments, improving stability, stopping distances, and driver confidence under heavy loads. Replacement as a complete module helps preserve system integrity and simplifies service in fleets with high mileage. Maintenance and bleeding procedures should follow the manufacturer guidelines to avoid air ingress and ensure reliable braking performance. Brought to you by Source One Parts Center.
