A few days ago i had brakes on my series 2, and last night i went out and had no brakes except with my foot flat to the floor, this morning checked the brake fluid reservoir to find it well below the minimum (strange it was topped up a few weeks ago) so i topped it up and still no brakes except if you pump the pedal (with which i noticed the revs went down on the car) or put it flat to the floor!!! have checked the brake pipes for leaking and cant find anything!!! it has had the abs disconnected and has standard discs and calipers, anybody got any ideas?????? cheers jason.
