The ABS pump was working fine as i said the pipe split and i changed it, obviously it lost all the fluid in the main res, now pipe has been replace, topped up with fluid, front brakes bled fine no issues, switched ignition on to run the ABS pumpand opened the rear bleed nipple, depressed the pedal, and nothing, tried for age but still nothing, the pump is running continuously while trying to bleed the system. i have the handbrake warning light lit now and pedal is rock hard. Any info please help
