@Grum looks like you live in $*££*w view where my mother in law lives at no 28.. i was in the street yesterday .. drop me a message if you need a hand ..im only in new duston,
Hope you have sussed it but if your pistons seized and the problem is intermttent then its a head scratcher. The only way this would happen is if youve removed the hub bolts - so the hub is floating so it will turn eccentrically. Tighten a whell onto it and it pushes the hub to where it should be and it fouls the shoe. You would have found this out if you had replaced the hub bolts and/or wound back the adjusters. Both of which you were advised to do. My assumptions above correct. You could always do the two things ive mentioned above as you may change the cylinder to then fing your hub bearings are goosed.
Ok, turns out the near side piston was seized. So that's been replaced & it's all good. But,,, I decided to change the drums too. I got a new pair from GSF. They identified my original drums as T25 Drums (I don't know anything as to /how/when/why) anyways,,, the new "proper" late bay drums have a raised lip around the edge of the face of the drum that is raised by 3mm. Sooo the bloody wheels still sit on the lip but there's no braking or binding issues.
The brakes are sorted but now it's the way they sit on the drums. They are from MWS so I'll ask those guys tomorrow.
Soooo. Spoke to Midkand wheels & told them the problems I've had. The reply: "oh the Black Empi 5's were sent out with 7mm spacers & longer studs, there was a mistake in the manufacturing process which lead there to be no raised center point on the reverse of the wheel" Solved.
So a mistake in the making of the wheel and they still sold them but with a work around using spacers and longer studs
Thank f for that...no wonder it was an arse to diagnose..... That's great PR for Midland Wheels then....What are they doing selling mis-manufactured wheels with a dodgy work round Proper ropey
