I successfully replaced my defective J72 Auto Park brake with a direct fit manual hand brake. This is the same E brake that GM Workhorse has used on there step van chassis ie. bread trucks, service vans for years. When our Auto Park failed and caught fire. The replacement from WH was going to cost $2,400 just for the brake assembly alone. Assuming the pump and actuator assembly were OK. If the actuator assembly were the cause the price for it could be another $2,000 plus labor on both. The manual replacement has cost less than $350 and that included all new parts. Only basic hand tools were required. I did have to fabricate a mount for the brake lever. The J72 is the new improved version of the Auto Park, and much different than the early style J71. Although this replacement should work on any Auto Park.

Was this a GM replacement part or aftermarket? I could use the brand name and where you bought the parts just in case.

Dale, have you also sent the above information to Roger (oldusedbear)? Also, did you just disable the Auto Park to return home from the east coast?

Hi Dale

I have a 2000 Flair 30 H, Workhorse chassis. I'm real new at this RV stuff and scared to death of the Auto-park. Old Used Bear sent me a lot of info and I have spent time under the rig to learn how to service and replace switches. Also learned how to disengage the park cable. So I am some what more comfortable with this system.
What is the web site for the mechanical park brake? I didn't understand "CLICK"

Saying all of this, could you go in more detail about this install
if I gave you my E-mail? Thank You

I'd be interested in the parts you used also. Saw a brake drum for $449+, didn't you use that, not necessary?
