+1 - usually pad deposit. Do the break in procedure again and twice if needed and it should sort it. If its really bad (you can see a pad imprint on the disc) then it might need further break in procedures done. Let it fully cool between each run though, dont want to cook it.
Thanks for the advise guys .... I tend not to use my brakes much .............. my original pads and discs lasted well over 50,000 miles ............this set was new about 6 months ago and I've had to use them a couple of times recently on the motorway at a lot higher speed than normal due to some idiots pulling out on me ............. it's not a bad sensation at all really ... just a very mild judder but I'd like to confirm it's not anything to worry about .......... fast cars need fast brakes
