Ultra RV J72 Brake Upgrade
Ok just received my upgrade kit from Brazel's and going to do the install tomorrow. Wondering if there's anything I need to know before starting? Should I use dielectric grease on the electrical connectors? Thanks in advance.

My Adventurer already had the Ultra RV brake upgrade when I bought it so I do't have of any pointers and the my Itasca doesn't have an AAPB. Jon and the technicians at Ultra RV products are always very helpful. They have a great chat line right on their webisite. Jon will often stop what he is doing and give people advice and pointers. If not Jon they have several other techs that are super knowledgeable.
So tomorrow, you might open their Ultra RV Products webpage and start a chat. If you can't get Jon or one of the other service techs right away then you can leave your number with one of the ladies on the chat. Someone will get back with you in short order.
The guys at URVP have probably installed more of these brake upgrade kits than anyone. They probably know every trick in the book to make the install go smooth.
Good luck.

Update: Installed the upgrade kit today from Ultra RV. Took 2 1/2 hours start to finish. Easiest upgrade I've done yet. Glad I did it as I had a problem trying to move the MH from my back driveway to my front one to work on it (brake wouldn't disengage). Hopefully that won't happen anymore.

Pretty simple really:
J72 Park Brake Module Replacement Kit replaces the factory park brake controller. Also incorporates the UltraSave Valve preventing the park brake from applying while the coach is in motion.

Workhorse owners are lucky to have UURP. What a great resource. I did a chat with them yesterday evening and it is was Jon that answered! I still have to wonder if the pump and actuator are also a weak link. Both can cause serious problems. When I had my P30 the next upgrade was going to be the air operated system. Unfortunately this is not available for the J72.

I ordered mine yesterday. I also ordered an extra plug for the original controller so I can seal out any moisture just in case I need it in the future. Always like having a plan b.
Question for the OP, did you bleed the system or pre-fill any of the hoses? Did the fluid reservoir drop much?

Only lost the fluid that was in one short hose (about 1' long). Didn't need to bleed the system or top off the reservoir. Easy install that will hopefully prevent problems in the future.

Thanks, that is my hope as well. At least if there is a failure it will be when stopped assuming no line leaks.
Did you inspect the power steering rubbing location?

Yes and it was rubbing. Bought a piece of 1" heater hose split it in half and slid it over the metal lines.
