Ok - pretty sure that its the ds2500 pads hitting the bells on the discs as the wheel goes round

I've had the pads off - angle grinded the metal off the back - fine for 50 miles and after a hard session (a few minutes) there back the same - I decided to pretty much take all the metal off and it makes no difference

Now - what I cant understand (and can someone explain to me) but the noise never occurs when I'm driving in a straight line, only when I had mid/full left (or) right lock on - obviously as the speed is faster the tap, tap, tap is worse - I'm 95% sure its the pads - and nothing else - but cant understand why the noise occurs on lock. (Its not the same noise as CV boot joints) - its almost like the pad is lifting on a part of the disc slightly as it goes round - seems to be much worse when the discs are very hot

(Its an AP 4 pot set up on 16's and the problem was never there previously - only when I changed the discs - and I seem to also have had problems with the discs - AP supplied me with out of tolerance discs.....which had to be taken off and sent back which seems to have sorted the incredible brake judder I got - but maybe it knackered the pads?)

Anyone had the same problems as me above

No brake experts?

is it vaguely possible that the discs are actuall too big, very slightly, and are touching the caliper when hot?? a picture 'might' help!

Discs are correct size

Re Piccie - just look like standard AP 4 pots.........

did you get this sorted ?

I am having a brake issue on my AP 4pots that I am trying to track down, I am not sure if its pads, sticking pistons, wheel bearing or what not, but I got a tap tap in a straight line and a "graaaaauuuunnnnnsh" scraping sound on turning sharp right at parking lot speeds
