Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Rear brake adjuster

So about to change a rear brake slave cylinder on my 2012 Plus 4. I think the existing one has been partially seized for some time, as the linings are too thin on that side for the 10k miles the car has done. So I have new EBC shoes to fit to both sides. The other side is fine but I shall do that one when I can get the another cylinder.

My question - is it worth doing the GoMog "filing down the adjuster" trick at the same time? Could I cause more hassle than its worth if they are fine without the adjustment?

I know the usual technique would be to do one thing at a time - but given i can't really drive the car to test it and i have time on my hands at the moment, it is tempting to take a belt and braces approach and do both at once.

I always get sound advice on here, so thoughts?

Nick, unless your drums feel like they are permanently binding, I wouldn't

Every Mog is different, some do, some don't and remember you will always feel some drag from the back axle, so they will never 'spin' freely

the adjuster is probably case hardened, and by filing, you will remove the case hardening. Leave well alone, and as long as the brakes work ok, use it!

Ok enough to convince me to do one step at a time. The side with the seized cylinder does bind and get hot, but the other is ok. So I shall do the cylinder and shoe change (both sides) first.

Thanks

Ah. Half way through reassembling the shoes and two issues. I've used EBC 6380 shoes as recommended. One issue is that the hole at the top of the leading shoe, which has a peg through it for the self adjusting mechanism, and is bigger that the originals by a mm or so - so the peg is a loose fit.
That's a concern. And the second issue is that the L shaped notches towards the bottom of both shoes are not present on the new shoes. These presumably allow room for the handbrake cable to bend towards the actuating lever. Are these essential?

The supplier has confirmed they are the correct shoes. Has anybody fitted EBC 6380 with success?

As it happens the original shoes are only half worn - so I think I shall put those back for now. Luckily it's a very easy job to fit them - NOT!

I've traditionally steered well clear of anything made by EBC.

If it wasnt the friction material coming off the backing on two sets of front brake pads, it was a set of rear pads having to be filed to fit the caliper.

I''ll only fit Ferodo or Mintex

And even worse now, the adjuster mounting pins are further apart on the new shoes - I have messaged EBC to see what is going on!

Oh I don't believe it - so the new cylinder doesn't fit either. I tried to save a few bob by using a BWC5099 cylinders and they have a wider spacing on the locating lug, but more importantly they have a wider body, and have an extra length of cylinder on the left, whereas the original have an extra length of cylinder on the right. I'm not taking a risk on brakes, so back to the drawing board.

Has anybody actually fitted reasonably priced cylinders and shoes on a post 93 morgan without paying morgan prices? And if so which parts did you use please.

There are three bonuses in this sorry tale - I now know a lot more about the brakes at the back, the suspect cylinder was rusted solid on one side so needs replacing anyway, and i have found a cracked handbrake cable sheath so I can clean and oil that and wrap in tape before that breaks.

But I am VERY frustrated!

I've just looked at Jon (Cooperman)'s photos of the official Caparo brakes and their cylinder has the extra bit of cylinder on the left. So are my originals correct??? Jeez this is confusing

Just looked back at that thread which was started by Craig Jez, and if you look at HIS photo, there is no offset at all! Think the main thing is the distance between the piston operating surfaces in the fully closed state should be the same as the original. Even if it is a mm or two different, the hydraulics will automatically compensate without danger arising.
I will be interested to follow this thread as I will need to do similar job next year.
Good luck.
