I fitted a set of new rear shoes 18 months back and I’ve had a problem with the NSR wheel locking whilst braking. I’ve just removed the drum and cleaned out the mud and crud etc and I’m now wondering if I fitted the shoes 18 months back the wrong way around!

There is obviously a leading edge and a trailing edge on each shoe (or primary and secondary shoe), but I just can't recall which way around these should be. Whilst I’m sure what I have is correct, I thought I’d just ask here for confirmation before I put it all back together.

Here’s a photo of the NSR (Left) shoes. Are they the right way around?

Yes I think they are.... the one at the rear is the handbrake shoe and therefore has more material on it (around the shoe)
Believe it or not I fitted them the other way a few years back and no difference..... maybe I had to adjust the handbrake more but still went thro MOT

Thanks. I thought they were right. I'll put it all back together. I did have a quick look in the Haynes manual, but it was not too clear.

I've discovered why the brake was locking. A small amount of the adhesive used to stick the lining onto the metal part of the shoe, had found its way onto the drum surface. They had probably run a bit hot when I first installed them 18 months back and the adhesive had oozed out along the trailing and leading edges. I’ve removed the excess adhesive with a knife and thoroughly cleaned the linings and drum surface.

Cut a chamfer on the leading edges of the shoes.

Cut a chamfer on the leading edges of the shoes.

Oddly enough, there is a chamfer on the trailing edge, which is what made me think I had them on the wrong way around in the first place.

Now I’m confused.

IIRC these were genuine Mopar shoes, so if they have a chamfer on the trailing edge have I fitted them correctly or should the other way around which would put the chamfer on the leading egde?

the chamfer is normally put on with the view it stops brake squeal

Brakes shoes are in the correct orientation. Did you equalise the adjusters properly?

Adjustment.

(5) Insert adjusting tool through support plate access hole and engage tool in teeth of adjusting screw star wheel (Fig. 60).
(6) Rotate adjuster screw star wheel (move tool handle upward) until slight drag can be felt when wheel is rotated.
(7) Push and hold adjuster lever away from star wheel with thin screwdriver.
( Back off adjuster screw star wheel until brake drag is eliminated.
(9) Repeat adjustment at opposite wheel. Be sure adjustment is equal at both wheels.
(10) Install support plate access hole plugs.

Adjuster equalisation.

(12) Drive vehicle and make one forward stop followed by one reverse stop. Repeat procedure 8-10 times to operate automatic adjusters and equalize
adjustment.
NOTE: Bring vehicle to complete standstill at each stop. Incomplete, rolling stops will not activate automatic adjusters.
