Part# W8005231-US

We have released a new parking brake pump for the autopark systems. This is a replacement that can be used on Workhorse Chassis 2001-2005 P32 and 2004-2010 W24 Chassis with the J71 and J72* auto parking brake systems.

  • This new pump is an upgraded design that has a larger motor and an integrated solenoid.
  • The larger motor provides more torque for longer life
  • The integrated solenoid design reduces the need for multiple external lines.
  • Unlike the factory pumps, this one allows for individual replacement components instead of the entire pump assembly.
  • Mounts to the same factory location of the original pump on all Workhorse Chassis.
  • Pump is a plug and play design, mates up to factory harness. Just bolt on plug in and go.
  • Pump assembly comes with the US21 UltraStop pressure switches that are rated at one million cycles and carry a lifetime warranty.
  • * To use with 2005 and newer with J72 it requires part# 5231-US harness adaptor.

Previous to the release of this pump assembly, there were not any pump options for the 2004 P32 chassis since 2014 when they were discontinued by Workhorse. If you have a 2004 Chassis there is now an option for you if you have a parking brake pump failure.
