Brake hang up

[Mr John]

I originally posted on 10-17 about my right front brake hanging up very bad. Put the unit in the shop yesterday and got it back today. $800 poorer. Replaced both calipers, new brake pads, new rubber flex hoses and various and sundry misc. parts. The shop (an independent Goodyear dealer I've dealt with before) said that the pistons were very rusty and not letting the pads retract when the brakes were released. after sitting for a short period of time, the pistons pulled in enough to let the MH move. Their suggestion was to use the MH on more regular basis, every couple of weeks drive it for a while and excersise the systems. This is something I do, however the previous owner did not and the MH sat for 3 or 4 months at a time. I've only had it since April and put 4,000 miles on it doing short trips of 100 to 350 miles on it. I guess I was lucky to get that many miles before the trouble showed up. Only time will tell if the problem rears its ugly head again.

Had the same problem with our class c we have a 2003 Dutchmen with a G.M.C. chassis,the front right brake would sticking once in awhile,then got to stick more often,they would stick and after a short time would release ,some say it was sticky calibers,others say it was the flex hose,after a lot of trial and error,come to find out it was the master cylinder good luck with yours Arthurge

i had the same issue, but both rotors were shot as well. they were cracked in many places, some all the way through. so, same as you plus rotors and ball joints and a brake system flush. 1700 clams! more than i paid for the rv! on the plus side, i got it back the next day, and didnt even get my hands dirty.

Lube the caliper slides every year and flush brake fluid at least every other year.

As these units sit, the braking systems continue to age, and they absorb water. Especially and the calipers, master cylinder and wheel cylinders. In a caliper, this is dangerous, as it speeds up galling (corrosion) and will expand as it warms up, causing unneeded friction. the brake fluid should be flushed annually, IMO, and your system will last much longer.
