Product Description
The Bendix K156037ORX M-40HF ABS Modulator Valve is a remanufactured heavy-duty braking component designed for compatible commercial vehicle anti-lock braking systems. Working with the vehicle's ABS electronic control unit (ECU), this valve regulates compressed air delivered to the brake chambers, helping prevent wheel lockup and maintain vehicle stability during braking.
The M-40HF high-flow design provides rapid pressure modulation, allowing the ABS controller to increase, hold, or decrease braking pressure as road conditions require. Its integrated solenoid valves respond to electrical signals from the ECU to support controlled braking performance during ABS activation.
Designed for demanding commercial vehicle environments, the K156037ORX features a durable pneumatic housing, sealed electrical connection, and threaded air ports. This remanufactured assembly provides a replacement option for compatible ABS modulator configurations.

The M-40HF modulator helps maintain appropriate wheel rotation during ABS activation by controlling compressed air pressure at the brake chambers. Its high-flow configuration supports responsive braking performance on vehicles equipped with compatible Bendix ABS systems.
The modulator is intended for use with compatible relay valve arrangements. Bendix 803115 is an R-12 relay valve with a 5.5 PSI crack pressure, but the compatibility of this exact combination should be confirmed before installation.
Before ordering, verify the original modulator part number, operating voltage, connector type, mounting configuration, and air port sizes. Different ABS modulators are not universally interchangeable, and some replacement installations may require additional electrical adapters or fittings.
