Hi
This is a strange one I've changed the wheel cylinders on my series 111 88 it's a 11 inch drum twin piston type .

Now the drum won't fit , checked all the obvious things adjusters right back , bleed nipple open so pistons are right in .etc tried loosening off the cylinders to allow them a bit of give.
my mate managed to force one drum on this evening but it isn't usable far too tight!! hope I can get it off again!!

I've only changed the cylinders so there sould be a good bit of space with the part worn shoes .

Only think I can think of is the new cylinders are longer , seems unlikely, I've contacted the supplier Aber' 4*4 who are very helpfull and been in buisiness for a long time they say they've been selling thes for years so they are the correct spec,
the only differance I can see from the old ones is the new ones are aluminium with a steel piece where the but end of the shoe fits.
Anyone had a similair problem?
Regards
Paul

you need to run yer finger around between the shoe and the lip on the back plate to make sure that the shoes are central

yes check that the shoes are level and equally space there may be too high at top meaning they wont work but press the pedal for the other one and it might loosen up !!

OK ..... LOGIC now ....

the drum won't fit over the brake shoes.

can we assume the SHOES are the right ones?

If the shoes are the correct ones, then there are only a few possible causes.

1. the adjusters are holding the shoes OUT too far - so undo screw OUT the adjusters.

2. the slave cylinders are not returning fully or are the wrong ones, or are not fitted centrally.

3. some slave cylinders have springs in them to hold the pistons gently out. In this case it is especially important to fit the brake shoe springs properly, almost invariably with the STRONG spring at the slave cylinder side.

4. the brake shoes are not properly seated, thus the linings are not parallel with the drums because the shoes are leaning out in the middle.

4. with new linings and old drums, the wear lip on the drum may be enough to stop the drum going over the lining - angle grinder job ....

Don't use violence in this job. It must be resolved by non-violent means.

Hi CharlesY
Thanks for the logic helps to work through .
the shoes are the same old ones taken off so the right ones
1. adjusters are right back, off.
2.the cyliners are right in, no fluid in there yet so nothing except the springs to hold them out.they shold be centrered , I loosen off the back nuts to allow them to find their own position with the drum, I'm assures by Aber 484 that they are the right ones ? are there any other landy single piston cylinders they could have given me by miskake ??
3 the shoes seem to be paralel with the drum , not sure what you mean sitting out in the middle?
4 these are old shoes and the old drums and the drums aren't badly worn so this shouldn't apply.

So still a bit of a puzzle , unless it is the wrong cylinders, but is that likely Aber 4*4 assure me they must be the right ones .
are there any other landy cylinders they could be??

Regards
Paul

Take one brake back apart, and try-fit to reassemble using the original slave cylinders.

Proves something if the drum goes back on!

Or not .............

Thanks everyone for your help with this problem. After removing new parts and replacing the new bits with the old it seemed the problem was with the new parts perhaps a case for buying original parts?
