Hi all, I've got a very annoying high pitched squeal coming from the front offside brake. I have taken it all to bits and airlined all the dust away and copper greased metal-to-metal areas. Loads of wear left on the pads, torqued it all back up and first of all noise was reduced about 50%. After 2 days [40 miles] the squeal's back with a vengeance.
P.S. It doesn't happen when braking hard, or at speed, but its at its loudest when braking very slowly say for instance pulling up at the lights.
Any help/ideas would be appreciated.
P.P.S. Before anyone says "oem pads" they are orig Vaux fitted by main dealer as last owner was an airline pilot and had all servicing done at main stealers. I've got all past receipts.
Wheres Andy B?

never known this to work for more than a week. Brakes are no place for copper slip imho. Guarantee you'll never find it "factory fitted"...however you will find no problem with oe pads (jurid) which have no leading or trailing edge shamfer, limited dust and better feel/bite...
try swapping the pads to the other side, either inboard to outboard or wheel to wheel, trade club pads used to be marked directional, and iirc have 1 shimed pad per caliper, try juggling the combinations ie both shimmed pads on the sqeaky side, or add your own shim material, they are only stuck on with double sided tape on the trade club pads, oe are rivetted see below, trade pair club at the top, 4 oe at the bottom

also note the oe pads shims extend round the edge of the metal pad backing to prevent the caliper touch the pad and resonating

shame oe pads are almost 70 bloody quid...

to op, try swapping the pads around...

also maybe something jammed in there as said.
