    My car is starting to make a funny sound from the break disc area on the passenger side when I'm not even breaking .. Took the pads out and noticed on the inside of the disc there is a massive grove and the pad has uneven wear .. Could this make the binding sound that I'm hearing ??

    Put new clips on yesurday .. As the break pad is not flat on the inside I'm pretty sure it's that making the noise . Discs and pads came from euro car farts.. I've had a few things from them now and are ment to be vag items but there no where near the same .. Gonna buy my parts from audi from now on

    I had pagid pads from ecp and they were a tight fit,the pads squealed so i changed them for another set, they slipped in comfortably and now no more squeals.

    Gordy how much were the clips just out of curiosity?

    I used ECP pads and discs on the rear and had no problems
    Just my fronts squeal bad but I haven't changed them since I've had the car in 3 years and they've still got loads of life left in them

    Just had a good look at my breaks and I think I've found out what's wrong the inside egde of the disc has a rusty lip around it and the pad is just hanging over so I'm thinking the sound is coming from there so out with the grinder tomorrow and shave the pad a little

    Don't put copper slip on the sliding pins, there is a special lubricant that should be put there, best to leave them dry than use copper slip...

    Good to here mate
    I'm going to sort my squeak out this week, I think the pads are too right against the carriers so might just need to grind a tiny bit out
