Looks OK. I can't see the pull-off springs very well. These are not symmetrical. You have correctly fitted them behind the shoes but I cannot tell if they are the right way up. There is a long spiral spring part and a short spiral part with a straight wire in between. The short spiral spring part goes nearest the piston. The idea is that the piston cannot foul on the spiral spring bit.

The picture is of Wolseley 1500 front brakes but the same principle applies.

Ah! The 7" front brake springs are symmetrical. The 8" front springs are not or at least what is currently being sold isn't.

Looks good to me too. As a tip, its always a good idea when doing jobs that require dismantling for the first time to take a photo/photos.

Although, always good to check the manual just in case the previous owner fitted something incorrectly in the past..... :wink:

Definitely. There's a guy on the FB group asking about brakes and his brakes are definitely not standard Minor drum brakes. I don't know what vehicle they came from!

Bottom shoe way off centre, adjuster slipped sideways but you've fixed it now anyway.

Now you have the drums back on, push the brake pedal down hard a few times. This helps to centralise the shoes before you try to use the shoe adjusters.

What I did was undo the bolts a bit holding the cylinders and drum when straight on, I then tightened them up, just the rears to do, I'll do them Saturday as want on brake cleaner.

Umm...they just needed a bit of wiggling/jiggling to get everything lined up properly.

Yeah... Whether double or single piston layout, or with shoes top/bottom or left/right, all I've ever done is hold the drum slightly further towards the car at one of the spots where the 2 shoes end, i.e a piston. With that part of the drum a few millimetres onto the shoes, press across and in at the opposite side to centralise on the shoes, them adjust the position to line up with the studs...
That sounds more complicated than it is. :-?

Good luck. I find the rears considerably more difficult than the front. The pull-off springs are very strong and the beehive springs are an absolute pain to fit. Allow more time than on the front.

I found that after replacing the cylinders (but not the shoes as well) that the handbrake needed adjusting. See workshop manual for how to adjust the handbrake correctly if required.

That's for that advice, and that spring looks like trouble, it's a beast of spring, no doubt I'll be cursing some doing these 😂
