Disc Brake Head Unit, PSP
SAF-Holland

Designed for disc brake-equipped trailers, this head unit supports hydraulic actuation and caliper engagement in PSP brake systems. It converts hydraulic pressure into controlled brake response, delivering consistent pad displacement, predictable bite, and reliable pad wear monitoring across varied road conditions and temperatures. The head unit is engineered for robust valve geometry, corrosion resistance, and resilience against vibrations common in over-the-road service. As part of the Trailer Axle and Suspension family, it integrates with standard brake line interfaces and control logic to facilitate reliable stopping power and rapid response to operator input. The VMRS code identifies its braking-system function, aiding in cross-referencing with compatible calipers, rotors, and actuator assemblies. When retrofitting or replacing, verify brake system compatibility, mounting dimensions, and fluid compatibility to ensure safe and efficient braking performance in demanding fleets.
