I have a 59 reg 1.6 focus dielsel, and have a problem when braking. I can hear a grinding noise if braking harsh-ish, doesnt do it when braking normally and the noise is accompanied by a nasty vibration through the brake pedal. The problem has been happening on and off for a couple of weeks. The brakes were checked by a main ford dealer about 2 months ago.
The problem occurs either when braking going over a speed bump, on ice, or braking when going over an uneven road surface. This is making me think it has something to do with the abs, but as a complete novice this is only a guess. The brakes are great at all other times.
By coincidence the car is going into the garage for its MOT on Saturday, and I've asked them to take a look, but I'd like to have some idea beforehand.
Thanks for any help you can give me
