    just got a 2nd hand mastercylinder as the the old one was cracked after a drop...



    got it from a local shop - they said they couldnt vouch for the internal seals - so I said lets not waste time there then - and bought a new set for it..



    they offered to install them for me and I thought why not?! so they did!



    anyways I am now having trouble bleeding the brakes..



    have placed the caliper higher than the master cyclinder - and have pumped and pumped!



    at first it looked like the fluid was going down - but now its stopped!



    a bit of fluid has started to surge out the bleed tube - but its not really getting anywhere!



    this is my 3rd time doing this in the last coupe of months - and this hasnt happened before!



    any one have any suggestions for me please..





    ( i replaced the caliper piston seals as well this time - they seem to have gone on ok... )

    Nothing like solving a problem huh? I use a turkey baster with some clear fuel line on the end to bleed brakes. Works a treat!

    a turkey baster? so that sucks the air out?



    I scored a syphon pump for US$1 and that was going to be my next go!

    I use a shop vac, duct tape, and a piece of clear tubing. Bleeds anything. Make sure you have someone to pour quickly from a big bottle of brake fluid.

    Turkey baster is used to reverse bleed the system. Stick the end into a bottle of brake fluid,give the bulb a squeeze and let the fluid flow into the baster.Connect the clear fuel line onto the bleed valve on the caliper making sure there are no air bubbles. Crack the bleeder and give the bulb a squeeze and watch as the fluid is pumped into the master cylinder.As air bubbles like to rise this method works very well and is cheap and easy to make.

    If you decide to make a baster bleeder for yourself I'll give you some tips. First off use a small hose clamp or plastic cable tie to afix the hose to the baster end. Also a cable tie or hose clamp must be installed on the bulb to keep it from coming loose from the body. I found this out the hard way. Giving the bulb a hard squeeze it slipped off the body and I had brake fluid everywhere and more air in the line!!
