MG MGF Technical - Brake 'Clip'?

Hi i own a '96 VVC and whilst replacing the discs and pads at the weekend found that one of what i believe is a retaining clip ( thin metal plate top and bottom of pad carrier in shape of ']' ) had snapped and the other disappeared completely. I tried fitting the pads with out these but they get an awful lot of movement in the carrier (at least 2mm in each direction). i cant see these clips listed on any of the usual suppliers sites. Any idea what the correct term for them is or where i could get some?

Anti-rattle plates/shims/springs, I suspect a fresh set may be included with OE pads but probably not with pattern parts. An MGR dealer may be able to supply just these, however it may be cheaper to order your next set of pads now once you've checked new plates come in the kit.
2mm is a lot of movement, so the backplates on the new pads must be appreciably smaller than standard, but you can usually achieve the same job as anti-rattle shims with a liberal spreading of copper grease.

the pads i fitted were ebc and identical to the oem ones i removed. I made do with using a liberal amount of copper slip but it appears to have just bee squashed out. Guess i better ring my local Rover bods...

The Instructions with your EBC Pads told you that the OEM Anti-Squeal plates should not be fitted.
You should not use a 'liberal amount' of copper slip but the absolute minimum. Any excess may get onto the disc/pad faces causing braking loss.
Would suggest that you strip out the pads and remove the copper slip and reapply. If there is any on the pad faces, then they need to go in the bin.

I believe the quite well proven history of greasing the backplates & sliders with copper grease stems from primarily its properties of not wandering about even when very very hot, and secondly its vibration absorbtion, so provided you don't actually butter it onto the friction surfaces, all is good. The anti-squeal properties work best when there is a collar of grease around the piston face, this damps the vibration & reduces the chatter of the plates in their sliders. By 'liberal' I mean 2mm or so thickness spread across the piston:backplate contact area (which will form into a collar), more like 1mm along the contact areas of the outer backplate, and a smear along the sliders. Slight squeeze-out is perfectly normal, in fact it's desirable!

I have used copper grease aswell but there is still a great load of squealing...
Is this because the brakedisc needs to be de-glazed? if yes, how do I do it?
does the sound occur due to that the pads are new, the discs are not?

PLease help us! :D

If you got the GreenStuff pads, I found they do squeal a bit more than the standard stuff but it was mostly only when cold and slow speed, gentle braking. When used properly, they were as good as they should've been! :p
