Wow, where do I start, this has been a huge learning experience.
So Monday I called Monaco and got the missing serial no. I needed for the rear (drive) axle. It was not on my build sheet but no one knows why.
2003 Monaco Signature rear axle Model no. 22060SH serial no. HN00932760
I think I had called 5X and emailed Dana Spicer on Saturday to no avail. But Monday I got the real phone no. for tech support who emailed me back the part no.s.
Dana Spicer tech support 419 866 3951 email@example.com
front and rear hubs are Webb. The part no.s below are Dana's. But the rotor is only available through Bendix. The pads are Spicer.
front and rear rotor no. 976030N
pads are 976003N
Fleetpride located 3 rotors available in the US and Canada. We will change the 2 drive rotors for now. $450 each. the pads are $180 for one axle.
So on Saturday and Monday we went around and visited some shops.
JBJ Diesel motorhome shop rate was 155/hr. They have not gotten back to us for an estimate. Their truck shop rate was 110. The higher rate was due to difficulties with transmission, engines and problems finding parts. None of which applied to our brake job. It was a very nice shop though.
JG Peterbuilt Their shop rate was $125/hr. Couldn't find the parts and didn't have the right jacks.
Rush Truck Centers shop rate $80/hr. They didn't care about using our parts. They do have a place in the parking lot for us. They are quoting us $400 for labor for the 5 hour job. They have tried to cross reference the parts to use a different brand for the front 2 wheels but there was no match.
They have been in business for 50 years and have 120 locations nationwide.
We did look into all the recommendations and there are a lot of truck shops that will not work on motorhomes. We did not go to Alignment Specialists because they were closed Saturday. But thank you Jim and Angie anyway.
attached is the TMC Recommended Practice that Webb sent me. I believe it is similar to what Vito posted. TMC RP 652-ADB Inspection.pdf
My part no.s are the same as what CountryB posted on the second page but not the first.
Lastly to RobRoy, we don't know when that rotor cracked, it may have been the last straw for that rotor. We were doing about 50 mph and only used the brakes to slow for a turn. The nail holes in my armrest can attest to that. Perhaps it isn't, I didn't take the picture and there is not consensus as to what the picture is showing. Ill take some more once we have it off. And thank you so much for the break in information!
I'll update again.
