lineaway Posted June 8, 2014 Report Share Posted June 8, 2014 Did you only change the master cyl. or did you do the clutch plates too.? Did you fill and prime before you attached the cylinder. Quote Link to comment Share on other sites More sharing options...

0007 Posted June 8, 2014 Report Share Posted June 8, 2014 First bleed the master Pump it a few times, hold the lever in and crack the banjo bolt, do this until you get no air Remove the slave, press the piston all the way in and put a clamp on it Then bleed for about 10 hours til you eventually get the hose free of air (total pain as the master flows very small volume) If you have a vacuum bleeder you could suck the fluid from the master down to the slave which works a lot better Quote Link to comment Share on other sites More sharing options...
lineaway Posted June 8, 2014 Report Share Posted June 8, 2014 You just need 3` of clear hose attached to the slave. Have the hose held straight up past the handle bar level. 5- 20 minute job. Bleeding does take patience. Quote Link to comment Share on other sites More sharing options...
dadof2 Posted June 8, 2014 Report Share Posted June 8, 2014 http://www.ebay.co.uk/sch/i.html?_trksid=p2050601.m570.l1311.R1.TR3.TRC1.A0.H1.Xvacuum+bleede&_nkw=vacuum+bleeder&_sacat=0&_from=R40 See above link. As you can now buy vacuum bleeder kits for well under £20 there is no reason not to have one. Regular changing / vacuu bleeding of brake and clutch fluid prevents a lot of the problems you read about on TC Quote Link to comment Share on other sites More sharing options...
lineaway Posted June 8, 2014 Report Share Posted June 8, 2014 I have found my vacuum pump sits on the shelve as the long tube works the best. Give it a try, I laugh at the hours I used to spend doing it any other way. Quote Link to comment Share on other sites More sharing options...
0007 Posted June 9, 2014 Report Share Posted June 9, 2014 Vacuum bleeder isn't really neccesary, but you still start at the beginning and bleed the master, if it's not pumping fluid ............... Quote Link to comment Share on other sites More sharing options...
