General Ducato Rear Brakes Binding

[adriank]

Update on my binding rear brakes. It failed the MOT because they were binding. Cleaned them up and it passed, but I wasn't totally happy without understanding why. I got the proper screws to remove the drum, M10 x 1.5 pitch. I checked the cylinders and peeling back the dust cover, one looked damp. Luckily I have a friend in the trade and I asked him to order me a new cyclinder. He advised getting two as if one was on the way out, the other probably was. Between looking and him replacing the cyclinder, about 20 miles, the seals had sprung a leak, luckily the shoes were dry. Replaced both cylinders, each had a piston seized.

Nearside Rear Wheel still binding on 2003 Ducato.
As I suspected, all the garage did was to slacken everything off to stop the nearside wheel binding. The problem now is that it has left me without an effective hand brake.
I found this out when we camped on a slightly sloping site this weekend and it wouldn't even hold on the leveling chocks. The handbrake travel is from horizontal to near vertical at about 8 clicks now.
Checking underneath and applying the handbrake slowly, I could see the travel on the handbrake cross brake cable between the two wheels was significantly more on the off side than it is on the nearside wheel. So after three clicks of the handbrake the nearside wheel is locked up solid but the hand brake on the off side not engaged at all at this point. Even at six clicks of the hand brake the offside wheel is still not fully locked up.

Adjusting the central rod to reduce the travel on the hand brake lever merely makes the nearside wheel bind up altogether. It doesn't take up the cross cable slack evenly. One side pulls up about an inch the other side about two inches.

Is there any individal adjustment that can be made to equalise each wheel hand brake travel within the drum it self?

I have just joined the forum and have a 2006 Ducato motorhome, with the rear nearside brake binding and getting quite hot. I note that it is a year since you posted the problem. Oct-10 now Oct 18-11. Did you resolve the problem? Can you offer advice?

I have just joined the forum after my motorhome failed the mot. I have been a mechanic for over 30 years and i dismantled the rear hubs to find similar problems as others. I adjusted the shoes down as far as it would go on the shaft just to see if every thing was clearing and reassembled rear hub on both sides but about 1/8" from the hub engaging on the centre hub they seize! Nothing to do with handbrake as nothing to interfere with with assembly. Have noticed shoes are tapered though will be replacing everything and try to find the answer! In due course seems though the shoes are wider than the recess drum hub!!
