hi im new to the club i just brought a is 2oo it needed new brake disks and pads after fitting i run them in for 300 miles after that they began to judder in very light braking so i thought the front disks where warped i brought another new pair for the front and run them in for about the same milage but now the same thing is happening again they seem fine at 1st but after about 10 miles there doing the same as the others it seems they only do it on light braking not heavy any ideas on what i can do apart for changing again with a vented disk ?
