Upon giving the Coach the once over, found a rear brake slide hung up and rotor gone, looks like its time for a little fun with brakes and hubs. Does anyone have the part numbers handy for rear Rotor, pad set, caliper helper spring kits, and axle seals for 1999 U295?
Bruce,
If they are Meritor brakes use this link:
VisualSearch (http://xpcatalogna.meritor.com/VisualSearch.aspx)
And of course Barry's excellent site for info:

Meritor site won't work in some versions of Firefox so use internet explorer with all the blockers turned off.

Bruce,
I had something similar, one end of a pad worn excessively from dragging, which I caught just before metal was about to contact the rotor. I didn't have to replace the rotor, but pads, pins, and bushings were replaced on right rear. I did the work, but it wasn't fun. Had a machinist replace the bushings. Needed a friend's help to remove and replace wheels. Most fire trucks have air disk brakes, so ask the fire department who does their brake work. Not many truck shops have experience with air disk brakes. If you enjoy that type of work the Meritor manual explains it in detail. I think my problem was caused by the pins and bushings. After 10k miles the new pads appear to be wearing correctly and not dragging. Don't have access to part numbers at the moment.
I had to replace two rotors after a trip to Alaska a couple years ago. At that time the rotors were $350 each. I don't have the part number handy, but FT only had one in stock, so I bought the second one through NAPA in just a couple days.
I have done the front wheel seals and lubed the brake pins and bushings, Just trying to find the right parts as I can't leave it torn down in the company shop got to get it done over the weekend. You are correct most of the truck shops don't have any exp. with air disc brakes
With a shop it shouldn't be much of a problem. On my coach, I am about 95% sure the front and rear brakes are the same (caliper, rotor, and pads) the air chambers and slack adjusters are larger on the rear for more brake force with 2 tires vs 1 tire. End result is rear pads wear out faster than front. Going to the coach tomorrow, will look for part numbers. The parts department at FT can probably give you all the part numbers if you supply them the build number. I think the Meritor manual says not to lube the pins and bushings, just keep them relatively clean. Be sure and read the part about lubing the calipers, and slack adjusters (special grease and procedure). If not done correctly a good possibility of a dragging brake. You probably know that, but others might not.
Jerry, F/T helped with the P/Ns, got all the parts locally, and yes the grease for the calipers is a Temp clay base grease, and is hard to find, my oil supplier came up with it after he called Meritor tech assistance to make sure he had the right product. Most people don't know that all greases don't mix well. I will enjoy some brake service and repairs next weekend or 2. Thanks
Let me know your source if the prices are decent. I'm just down the road from you.
I had good brake work done on my 93 U280 brakes by SouthEast Power
Southeast Power Systems (http://www.se-power.com/)
Cummins coach care won't touch RV disks - they aren't trained. At least they're honest.
Dave I have used SouthEast Power on the trail for some of our company work, and for HD starter and Alt rebuilds as well, they do a good job. Also they do Cummings warranty work at their Daytona location. The parts are coming from Orlando Truck Parts in Taft. They had to order the rotor all parts will be here by Friday, I'll post the prices when I get the parts, didn't ask the price gotta have e'm, but they are owned by my AC Delco supplier, I get like 45% off of list.
Dave, got my parts from Orlando Truck Parts, Rotor $210.00, pads per axle $225.00, Caliper pin kits ea caliper $136.91
Installed it all this weekend 8 hours on the rear axle (replaced 1 rotor what a bear to get the nuts off)
