I have a 96 2.0 16v, when I apply the brakes I get a noise that sounds similar to a playing card in the spokes of a push bike, the pedal firms up, and really bad vibrations back through the pedal, this has actually started happening when im not applying the brakes as well, which is wierd, I recently replaced o/s abs sensor which didnt fix it altough when the abs sensors are disconected the problem went

any help would be muchly appreciated
