I have a 1977 Shasta motor home built on a dodge 1 ton van chassis. I just started it up yesterday after setting for a couple years. It all seems okay accept the back brakes don't want to let go. Can you please tell me how to get them un-stuck again. It will go but they drag. This does have the duel rear wheel set up. Thanks
Hello Todd
brake shoes probably have rusted to the drums---and more than likely need to be replaced as well as the wheel cylinders--you could try bleeding the rears---be very careful not to break off bleeders---any brake fluid should be bleed off/ changed every 2 years

Did they lock up after using the brakes or were thy locked up when you went to drive it.
It could be the proprtioning valve which distributes presure between the disks and the drums.
Rubber brake lines could be the problem also. Old rubber lines will sometimes let the pressure through then collapse as soon as you take your foot off causing the pressure to remain in the drum.
Yes I think the shoes were rusted to the drums, I had a little trouble getting it to move at all in the beginning and when it did it broke loose with a good thud. I'll try bleeding them to at least relieve some residual pressure. The rubber lines are definitely old but everything was working good when I parked it, I think I just left it parked too long, it only has 49000 original miles.
Can anyone please tell me how hard it is to work on or get to the brakes with a 1 ton dually rear end? I have worked on several cars, but nothing built this heavy I guess I'm a little apprehensive to just start tearing into it. Thank you for your replies and any additional information you can give me.
I was looking at my rear axel and thinking the same thing about it being heavy duty. I definitely need new seals all the way around on it and am debating doing it or taking it somewhere.
Logic pushes me toward the theory that the rear end is the same as any other vehicle except the parts are bigger. Tear into it and let us know how it goes. Those rubber lines are going to plague you in the future so spend a few dollars now and fix them while your under there.
