    Brake bleed fail... No brakes

    I fitted new disks and pads all round today had to take one of the rear calipers off to wind it in... Bother we're wound in, when I bled them each calipers was done at least 5 times with short drives in between and the master cylinder done twice by the ed of it all the fluid exiting was clear, there was 2 of us bleeding one pumping the pedal one operating the bleed nipple, we friend engine on engine off start from the furtherst away from the MS Ect... The pedal feels ok when the car it off but when the engine is running it bottoms out and the brakes are awful. I can't drive the car because the stopping distance from 15 mph is about 30 foot lol... Anyone point my in the right direction please?!

    bleed the MC again, but do it this way, slacken the bleeders, press pedal to the floor and hold there while you tighten the bleeders, do this 5/6 times and you will have a good pedal feel

    Honestly try getting a brake bleeding kit; makes the job at hand so easy and its a 1 man job and more importantly stress free.

    Flipped seals I bet. Master cylinder dead. New one required.

    NEVER bleed these cars using the two man method pressing the pedal. Ruins them

    He just stressed to me to keep the reservoir FULL

    As have I and a ex-VW Racing mechanic I know, for years. Only seems to be a problem for people on here You should always keep the reservoir full. Pressure/Vacuum bleeding will be easier though.

    I don't want to replace the mc willy nilly could be a waste of money, there is no fluid leak around it and how can you tell if its that that's gone?

    It just will not bleed up, there will be no leaks...

    Its just the age of these now Sam, that little ring you get where the seal has happily sat for 10 years+ will have certainly formed, and i believe it is this that flips them..

    Formed with what though? It's a sealed system full of fluid? I can understand if you let the reservoir run empty and then pump air, there's a chance of causing issues.
