isitafox Posted August 28, 2010 Report Share Posted August 28, 2010 (edited) Are you following the instructions off hopes website?? There's nothing supposed to come out the master cylinder, thats where you add the brake fluid! Edited August 28, 2010 by isitafox Quote Link to comment Share on other sites More sharing options...

madmikesmod Posted August 28, 2010 Author Report Share Posted August 28, 2010 Could you tell me exactly what your doing step by step and I'll see if I can spot anything? ive topped the cylinder up with fluid, with the nipple open ive pressed the lever then closed the nipple then let go of the lever, i did this 10plus times but nothing is happening i know when you let go of the lever the fluid level is ment to go down but it just dont cheers mike Quote Link to comment Share on other sites More sharing options...
isitafox Posted August 28, 2010 Report Share Posted August 28, 2010 All I can suggest is that there must be a blockage somewhere in the bleed nipple or it's not opening fully. Is there fluid coming down the pipe? Quote Link to comment Share on other sites More sharing options...

Is there fluid coming down the pipe? the nipple does open but when i pump it once with the nipple open air comes out. then when i close it and let go of the lever, i open the nipple and the air goes back in.

isitafox Posted August 28, 2010 Report Share Posted August 28, 2010 Then I'd say there's definately something blocking the pipe somewhere which will be causing the vacuum effect making the bleed nipple suck the brake fluid back in. Quote Link to comment Share on other sites More sharing options...
