It's not an easy job but if you have the tools and a place to work and the knowhow it can be done. Yes drop the driveshaft and pull the brake drum off the transmission. Then it just looks like a regular brake shoe set up. I replaced the shoes, pins, springs, and adjuster while I was there. That was the easy part,
the control unit that makes all this work is the problem with auto-park systems.

.BRAZELSVRV.COM HAVE UP GREADES I think people who try upgrades on there own my be looking for real trouble. Can't understand why anybody would not ask a pro for a real safe fix after all locking up brakes can't be fun or safe while your driving.

I have had to replace the shoes on my 1998 Itasca with the autopark system after a RGS failed. I used #449 brake best select shoes from I think autozone. I just told the counter guy 449 and he knew what I needed. They fit great, about the only thing in the autopark system that does. I have done away with most of this system to get something that is safe to travel with.

How difficult a job was it to change the shoes? I assume you had to remove the driveshaft and rear cover to even inspect the brake shoes.

Gjac, what did it do when it let go at 60 mph? Were you able to drive it to a safe place to work on it? I am asking because I have a 2001 with auto park and have never had trouble with it but I know it can cause big problems and I would like to know what to expect if it fails. I do keep a spare green switch and watch the fluid level pretty closely.

I was able to drive it off the hiway to a store parking lot. I then had to adjust the parking brake off from underneath the MH. Twice I was able to just replace the green switch and be on my way after adding some transmission fluid to the reservoir. The auto park system can be problematic, Carry the grey switch with you also. That went on me once, it shows the auto park is on when it is not.

When that green switch leaks the brakes are applied, and when it lets go at 60 mpg it can be quite unnerving. Then you have to drive off the hiway to get to a safe place to disengage the brake. It is only two small shoes applying pressure to stop a 16,000 lb MH vs 8 shoes or pads in a panic stop using your regular brakes. After going through 3 green switch failures I can see how these brake shoes can wear thin.

Interesting that a brake shoe that never has to stop a moving vehicle would need replacing. I guess it could develop a stress crack. I had a P30 in the 90’s and at the MV inspection they applied the emergency brake pedal. I had never used it and apparently the cable had corroded and it froze locking the drive shaft (auto park) brake. I could move it to my mechanic’s shop, but I did need new shoes after I got there!

Yeah I'm guessing it's always the autopark being stuck that makes everyone replace, which is currently my problem. I ended up driving with it not knowing it was stuck on.

I have heard they are available as a generic brake part from NAPA for about $25, unfortunately I don't have the part number off hand.
