Re: brake cylinders leaking
Easy enough to change, no 'special tools' , biggest problem will be the brake pipe seized in the fitting, so may need a new pipe - will need new shoes too if fluid has got on the linings. I suggest change BOTH sides - and fit new linings and that's it set for another few months !!

Re: brake cylinders leaking
as BMC says no special tools needed, a brake pipe spanner is like ring spanner but with a gap to allow it to pass over the brake pipe. It is a nice tool to have if you are changing pipes all the time but for once in a while i would not bother. If you have fluid on the shoes I would be a bit stronger than BMC and say you MUST change the shoes on both sides of the car ( BMC sorry if i misunderstood what you were saying,not sure if you were talking about replacing both slaves or both sets of shoes )

Re: brake cylinders leaking
I bought a 7/16" decent quality (old Draper, I think) brake spanner years ago, and every time I use it, I'm glad I did! Definitely a tool to have if you are going to work on brakes. BTW, modern cars often use 11mm brake fixings and my old spanner works perfectly for these as well!. Other than that, rear brake cylinders can be hard to bleed properly, so, prime with brake fluid first and jack the rear of the car up and leave for the bubbles to find their way to the nipples. Both great tips i got from this forum.charlie_morris_minor wrote:as BMC says no special tools needed, a brake pipe spanner is like ring spanner but with a gap to allow it to pass over the brake pipe.

Re: brake cylinders leaking
If you are changing cylinder and shoes at the back- it is a good idea to change the brake springs as well-unless obviously recently changed- available from the usual Minor suppliers- don't need the "beehive spring". Also, inspect and clean the drum while it is off for excessive wear and scoring (wear dust mask in case of old asbestos brake shoes!!!) and look at the handbrake cable, which should not be frayed. Also a good idea while the drums and shoes are off to check for leaks from the rear hubs/halfshafts.

Re: brake cylinders leaking
I've never had the slightest bother bleeding rear brakes - even with new cylinders........

Even my size 14s won't let me walk on water! There really is NO problem bleeding these brakes - even I can do it. People shouldn't shy away from it - as if it is in some way mysterious and/or difficult!

Re: brake cylinders leaking
beehive springs are they the little round coiled springs, what are they/were they for?
one of mine broke and fell off. lol.

Re: brake cylinders leaking
They are intended to hold the shoes snuggly against the backplate - most folks throw them away!
