hey i was driving my car pretty hard tonight, started to get quite bad brake fade, pulled over and the discs were glowing cherry red! its on an fr 130tdi...the brakes have always felt abit spongey so wanted to see if i could burn some cr*p off them, it was quite severe fading at one point (to the point i had my foot welded to the floor) i know the discs and pads need replacing, probably do the fluid as well. Do drilled/grooved discs make that much different ? or will oem discs and pads be better? cheers
