Have changed rear cylinders, replaced brake shoes, changed back axle wheel bearings etc, bled brakes, no probs so far, since previous probs.

Springs etc all in proper place, wheels rotate forwards, but lock solid in reverse, this seems to be only on the offside wheel.....

Any ideas??

I have even chamfered both leading and trailing edges of the shoes, still no joy..... :eek:
 
Did that, all works fine,,,, even took half shaft out, and left drum on, still locked in reverse.....Free without drum

Only does it with the drum in place, points to the shoes, but why??:confused: :confused:

I take it you've checked that the springs are fitted correctly?

Yes, 3 times now...

Had shoes off drum on, turns freely....

It has to be the shoes.

Funny thing is, if you clamp the flexible tube before the axle, the pedal feels great, front brakes perfect, release the clamp, and pedal feels ****e, almost to the floor again, all this despite using and easybleed, no bubbles at all.

I digress though, it does not solve the probs of the drum locking in reverse...
 
Cylinder...

Reckon its going to be the next purchase, just to eliminate the bloody thing...

Have to admit even before I changed the shoes the brakes were crap, one pump and brilliant.... Put it down to a 35 year old vehicle without a servo....
 
I know this mite be dumb - but here goes.....
It used to be trick many moons ago to chamfer the front and rear edges of the brake material - helps stopping it snatching. Cant do any harm.

but re-reading the thread, if, by clamping the flex pipe, the brakes are much improved, I reckon the shoes are not being pulled back by the springs and are locking on - when driving forward, the drum rubs over the shoes, but when in reverse, the shoes jam into the drum and lock the wheel. Change the slave cylinder.
 
switch the rear slave cyls over, o/s to n/s, that will eliminate a poss faulty cylinder.
it has been known.

ive filed off the edges of new shoes many times and cured similar probs.
try another drum. they were never the most precise things ever made!
