sometimes when im braking just before the car comes to a stop i can feel like a grinding feeling coming through the brake pedal. the only way to describe it is it feels like the ABS is kicking in , it only does it every so often not every time, ive been away with work and whille i was away my brother borrowed the car and my red stuff pads went so he had some blue print ones fitted, i was just woundering if anyone had any advice on what it could be. thanks
