Going through the front brakes on the '86 , finding that parts for the Rockwell Q series are not found on every street corner . I have finally gotten new adjusters, air chambers, cam kits , shoe hardware kits , and a shop in Birmingham has relined the shoes . If I could start over I would upgrade to Q Plus , but here I am . Just had the drums turned , was excited at the prospect of finally being able to put everything back together .... then I looked closer at the drums...
One drum didn't clear up completely , and is at the max diameter ( 16.625) . Both have high spots in the freshly machined surface , no doubt due to local hot / hard spots that caused their tool to deflect . So the search for new drums resumes ..
The closest thing I have found is the Gunite 2920 X which is very close except for overall height . Just wondering if anyone has found a good source for the brake drums ?
Hope everyone is staying healthy during this C -19 thing .
Thanks,
Chris

Thanks for the parts list, not sure how my brakes are, but I'll be looking into them when I get my coach back. Did you look into converting to disk brakes?

No, I like the simplicity of the drum style brakes. My system worked well when I went through it. It’s been my experience to KISS. Maintenance and cost are less with drum. I’ve had many motorhomes, some with disc. I think the best in braking is when I had the extra set of brakes on a tag axle, and a transmission retarder, (better in town). Jake better in mountains

I managed to get the front brakes back together , wheels on and back on the ground some months ago . No test drive as yet , have been occupied with busy shop , compressor rebuild , belt drive alternator conversion , etc .
The brakes are straightforward as far as drum brakes go , S cam and air actuation being the biggest departure from the motorcycle brakes I have dealt with most of my life . Oh, and the king sized parts !
Thanks to Johnny for the organized parts listing .
Safely jacking and supporting these heavy vehicles cannot be overstressed .
I will attempt to attach a couple of manuals that I found helpful .
A few pictures added to my gallery , no particular order .
