Product Overview

The K056040 is a genuine Paccar ABS modulator valve assembly designed for compatible Paccar anti-lock air brake systems. This high-flow valve regulates brake air pressure by reducing, holding, or reapplying pressure during an ABS event. 

Product Features

The K056040 ABS modulator valve assembly is manufactured to Paccar factory specifications for controlling brake pressure during anti-lock braking operation.

  • Reduces delivered brake pressure when the ABS determines that a wheel is approaching lock-up.
  • Holds brake pressure at the commanded level when additional pressure could increase wheel slip.
  • Reapplies pressure after wheel rotation recovers and additional braking force can be used.
  • Cycles between pressure-control stages rapidly during a hard-braking event.
  • Limits sustained wheel lock by regulating the air supplied to the corresponding brake circuit.
  • Supports continued steering input while the ABS controls braking pressure.
  • Provides controlled pressure modulation for more stable braking on low-traction surfaces.

Installation Notes

The K056040 mounts through two 0.335-inch mounting locations and connects to the supply and delivery circuits through 1/2-14 NPT ports. Confirm the port routing and fully seat the circular DIN three-way connector before testing the ABS.

Verify part number K056040, high-flow configuration, 12V electrical system, and air-port arrangement before installation.
