smithy 1 Posted October 1, 2010 recently changed all the solid brake lines and when trying to bleed i was not getting any output from M/C trying to bleed furthest from master first working to the closest. I have fitted a new M/C but it is having exact same problem,when bleeding i can see level in resavoir move but nothing comes out of the ports. any ideas of what could be the problem? i find it hard to believe both old and new master have exactly the same problem.

You haven't stated how you are attempting to bleed the system, step by step would be good so that we could point you in the right direction. Use an Ezibleed kit which pressurises the reservoir, about £20 and save yourself the hassle, just don't bother putting any fluid in the bottle and use about 5psi.

jackherer 543 Posted October 1, 2010 If it is a 1.9 it could be bad compensators. Have you tried bleeding the fronts or have you just got stuck on the first rear one? I agree with Toddy's comments about easy bleeds, you definitely don't want any fluid in the bottle. However if it is the compensators blocking fluid flow you might want to try more than 5psi, I have managed to get them working again with a load of pressure through an easy bleed.

smithy 1 Posted October 1, 2010 Thanks for replies. Trying to bleed by just pumping the pedal using one of them bleed pipes with one way valve in.tried on front and rear brakes with dame result. Tried bleeding direct at unions on master but nothing coming out of any port. Car is a 1.6 3 channel set up. Will Give the easy bleed a go tomorrow Share this post Link to post Share on other sites
mickie 3 Posted October 2, 2010 (edited) i guess if nothing is coming direct out of MC then thats your problem, you could always try taking it apart.. but it almost seems like you're doing it wrong because even if the seals have gone in the MC fluid should still seep out of the MC Edited October 2, 2010 by mickie Share this post Link to post Share on other sites
