Description and Purpose

Parts Finder Q offers the Wabco - Meritor® ABS Brake Relay Valve, a 12V relay valve engineered to regulate air pressure within a vehicle's anti-lock braking system (ABS). Featuring a response pressure of 38 bar and a crack pressure of 5.5 psi, this valve is designed for optimal performance under demanding conditions. It supports a maximum operating pressure of 159.50 psi and operates effectively across a temperature range of -40°C to +80°C (-40°F to +185°F).  This relay valve is compatible with Freightliner, Kenworth, Mack, Meritor, Peterbilt, and Volvo vehicles, making it a versatile solution for commercial and heavy-duty applications. With its IP66 and IP69K protection ratings, the valve is resistant to dust, water, and extreme environments, ensuring long-lasting reliability.

Impact on Vehicle Performance

The ABS Brake Relay Valve ensures precise air pressure regulation, enhancing braking efficiency, stability, and safety. By preventing wheel lock-up during braking, it improves vehicle control and reduces stopping distances, especially in emergency or low-traction conditions. A functional relay valve is critical for maintaining optimal ABS performance and overall vehicle safety.

Why Replacement is Important

Replacing a worn or failing ABS brake relay valve is essential to maintaining proper air pressure, enhancing braking performance, and ensuring vehicle safety. This component is a vital part of the brake system, contributing to improved vehicle control and stability during braking operations.
