MuddyMachine Posted March 27, 2009 Share Posted March 27, 2009 I am having little luck bleeding my brakes. I have converted the fronts to Vented discs, with brand new callipers. The fronts have bleb OK, but the rears seem to just be just froth with lots of big bubbles. I have gone through about 5lts of fluid. I have also noticed there is bubbles in the master cyl, when pressing the pedel. It was ment to go for it MOT today, any Ideas cheers Quote Link to comment Share on other sites More sharing options...
crwoody Posted March 27, 2009 Share Posted March 27, 2009 Hi Baz, May be a little obvious but can you be absolutely sure that the master cylinder reservoir has been kept topped up while you've been bleeding the back ones? Otherwise maybe a faulty/leaking master cylinder drawing air back in from somewhere? Are you just doing it manually, IE 2 man job - pumping the pedal and letting off the bleed nipple under pressure? Have you tried an Eezibleed type system for example - http://www.gunson.co.uk/item.aspx?cat=674&item=1818 I've used one before and it makes it a lot easier, specially if your trying to do it on your own. Sorry to be a little vague but it's all I can think of. Good luck Clive Quote Link to comment Share on other sites More sharing options...
eds Posted March 27, 2009 Share Posted March 27, 2009 It is easier if you take it to a man with a vacuum system if you are struggling I thought it was an easy job but it actually can go wrong really easily I heard the vacuum system used about 5 litres of fluid as standard if your brakes are full of air I certainly won't try to change my own rear cylinders again after the hours of mess and worry I went throught trying to rectify my bad bleeding. I was told if the bleeding goes well it is done in 10 seconds with no mess, but if it goes badly it can take all day and a lot of mess!! My advice it take it to a nationwide as some places won't even touch your brakes if you started the job yourself or they will expect to strip and redo the job themselves entirely. Insurance problems! I am sure others will say it is easier than I describe but I failed so I am not too enthusistic about bleeding anymore. Ed Quote Link to comment Share on other sites More sharing options...
MuddyMachine Posted March 27, 2009 Author Share Posted March 27, 2009 I am doing it 2 man style, the resovoir is kept full. Have thought about getting a pressure bleed. Think I will just bite the bullet and take it to a garage. Cheers Quote Link to comment Share on other sites More sharing options...
