Can anyone explain the markings on one of my front discs, the car seems to stutter when cruising slowly, as though the brakes are being applied in the manner you can see on the disc, the other disc is fine and braking seems very good. All callipers are reconditioned and I have resealed my master and Bias valve.
Disc run out is 2 to 4 thou so thats OK.
Any help much appreciated, best Peter.
