there can be a lip on the discs where the old pads wore a groe, this means they are not making full contact when you brake and causing the squeal. so either a new set of discs or get them ground flat.

What pads and discs have you got?

I found mintex 1155 very loud but Ferodo DS2500s are quiet.

oh right, well the only other option is that its the particular types you have. good pads tend to squeal.

also only has to be a very slight lip

also how hard have you been running them? have you been flooring it then slamming brakes on hard for corners, and late breaking excessively?

is so drive it softly for a while and let the pads and discs do their work then be true with eachother.

hard braking causes this a lot, and it will take a few miles of soft eco driving to cure it. (a few meaning a few hundred)

yeah just let it squeal till it shuts up, if you brake hard your forcing full contact on to the discs from the pads, and this does no good.

I had EBCs on my FRS, were cheap but now I know why. Ive never heard anything squeal quite like it, was ok under hard braking but just gentle when you was going down the high street or something they were something else

i got the same mate on the GTi, last service i had new discs and pads which was about 3-4months ago, they were fine but in the last few weeks they sometimes squeal when braking gently from like 40-30mph, if i brake at 50+mph i dont get anything its silent.
It hasnt bothered me though as its not all the time and its not that loud either, yours sounds like its worse though

put a 45degree chamfer on the leading edge

and put silicone sealant along the ends of the pads where they slide along the calliper body (normally people do that to stop pad knock on race callipers but it reduces squeeling too)
