    1991 S2 With Suspect Abs Modulator Problem

    Hi all S2 members, need a bit of help!!
    Just replaced all flexy brake pipes as they were all either badly cracked or bulging, all went fine, i have a solid pedal as before, but the car has what i think is a slight problemor not as the case may be???

    When the car is not running the pedal is solid as a rock, when the engine is running the pedal takes on a hole different ball game, when pressure is applied to the pedal and held, the pedal goes down towards the floor????? this was there before, basically since i bought the car, so its nothing to do with recent work undertaken.

    When the brakes are applied they are absolutely sound and the car pulls up great, i just want to ask, is this normal with the Audi S2 ABS System or is it likely to be the ABS Modulater Unit in front of the battery????

    Regards Audimaniac
