US2078 - UltraStop Park Brake Module Replacement With UltraSave Kit

The J72 Auto Apply Park Brake, found on various Workhorse and Freightliner chassis, relies on a factory-installed park brake controller that is known to be unreliable. In some cases, it can engage the park brake unexpectedly while the vehicle is in motion, without any warning.

The UltraStop Park Brake Module Replacement with UltraSave Kit addresses this issue by replacing the faulty controller using factory connectors for a seamless installation. In addition, it incorporates a hydraulic line lock system designed to prevent unintended brake application in the event of a pressure loss.

We refer to this solution as the “J72 Disaster Prevention Kit” and strongly advise against replacing the transmission brake unit without also installing this system, as it helps safeguard your investment.

Product Benefits:

  • J72 Park Brake Module Replacement Kit replaces the problematic factory park brake controller
  • J72 Park Brake UltraSave Valve Prevents the park brake from applying while the coach is in motion
  • This kit is "Plug and Play" and installs in about 1.5 hours without the need for special tools

Applications:

  • 2005 Workhorse P32 Chassis with J72 Parking Brake
  • 2004-2007 Workhorse W24 chassis with J72 Parking Brake
  • **For Workhorse Custom Chassis W18 with J72 Parking Brake please see product US2078-W18**
  • Freightliner "FRED" Front Engine Diesel RV Chassis with Auto Apply Park Brake (Requires purchase and use of RWB144-01 kit)

Do I NEED THE W8001667 BRAKE LIT? WE HAVE THE Allison 5 speed transmission but brake works very well as mh is not able to move at all when parking brake engages.. ( Philip Gilmore, 07/13/2022 )

Phillip,

    In your other comment, you said "Brake has locked three times in the last two years" did it apply while the coach was moving? Or, it would not release when you took it out of park? If it applied while driving I would encourage replacement. Otherwise if it has not applied while driving, and holds when you give it throttle with the engine running, coach in drive, and the yellow push/pull button out, then there is no need to replace it.

Ordering whole kit
Brake has locked three times in last two years. Tow is expensive but most mechanics do not understand it. So needless work is done. We are on the road so will have it shipped to mom in laws home (26 N MAIN ST, ALBION, PA 16401, WE STILL HAVE 300 MILES TO GO TO GET THAT FAR. IF LOSS OF 12 VOLTS IS THE CAUSE (MAYBE ON GROUND SIDe), WHICH WIRES SHOULD I APPLY 12 VOLTS (+ AND 12 VOLTS --) TO IN AN EMERGENCY.?
( Philip Gilmore, 07/13/2022 )

Phillip,

    On the 14 pin connector at the controller, with key on, power should be found on pins 1 and 10, and ground on pin 14 for the 12vdc supply.
