Post subject:  Brake shoe problems
Anyone seen this before. The new front brake shoes from Road house has the return spring attachment on the outside and not the inside, see pics. This is causing the shoes to tilt outwards preventing proper centering of the shoes. Fitted 0 eccentrics as a test but same problem. Contacted supplier saying that Road house will not fit the taps on the inside, too difficult. :shock:
Looking for a new supplier but where? Roy a comment would be good

Have you tried it when the cylinder is in place and the cam adjuster is backed off?

The shoes look as though they're sitting further out than they usually are, which is putting more of an eccentric load on them... :?

I had no problem with the last set of these I fitted, good pedal and a reading of 170kg each side on the MOT test rollers.

( Got them from Roy, btw. ;) )

Yes the shoes drop back in when slacken the adjusters but when I bring the shoes out for near contact with the drum to set my centering tool, they tilt. This is the second set in 2 weeks :?

I haven't had a problem with these shoes, in fact the location of the spring seemed to make life easier when installing the shoes.

However, if you're finding them awkward, perhaps fitting stronger steady springs or packing the original springs with a washer or two could help?

Those LHM rear cylinders with the wrong shape of dust cover were a bit of nuisance, but no problem once a 'workaround' had been figured out...

I fit the shoes first without the cylinder, then bring out the shoes to make room for the cylinder.

I removed the taps with the grinder and welded them back on the right way. Problem solved.

Viking, Ken.
thats a tiny amount of friction material on the trailing shoe.Dont remember that form my old drummer......eek nearly 25yrs ago!

Viking, is there enough space up by the handbrake link between the two shoes to get the spring in? if so you could simply drill a hole in the plate and then the spring would act on the shoes in a much flatter plane rather than trying to pull the shoes up-more secure than re welded pins too.

Did consider drilling holes but space is limited. Handbrake lever in the way.

So done to equalise the wear rate for the leading/trailing shoes, I understand.
Holdens here in Oz did the same thing, but some early (30's/40's) Fords got around it another way by having the linings same size but with a stepped diameter wheel cylinder which gave more force on the trailing shoe than the leading shoe, hence equalizing the wear rate on the linings. It's all a lot simpler now that we can have disc brakes, no?

If the shoes twisted that much carnt help but think there is a lot of slack on the shoe pivots or in the hole in the shoe if you shimmed the eccentric it may have helped but it may have seized quicker as you have found citroen knew best :) when the spring is on the rear of the shoes surely its twisting action keeps it tight onto the back plate and hence the lining will wear square the spring in front will in time twist the shoe and wear the shoe differently.
