Aii_Aitch Posted May 21, 2012 Report Share Posted May 21, 2012 So, I've flushed out all the old water, taken off the lever and left the bleed screw from the lever out. I tried pushing the piston out of the lever casing using a hammer and a 3mm allen key, but it won't budge. I've also put some WD40 down the lever end on the opening to try and get some lubrication against the piston and casing. Can someone shed some light on the subject?

dann2707 Posted May 21, 2012 Report Share Posted May 21, 2012 Use some old maggy tubing attached to a bike pump or compressor and fire it ouy but cover your eye as it comes out with some mega velocity ! Quote Link to comment Share on other sites More sharing options...
Aii_Aitch Posted May 21, 2012 Author Report Share Posted May 21, 2012 Wow. Wasn't expecting that. How exactly do I get the pump and tubing to stay together? Quote Link to comment Share on other sites More sharing options...
dann2707 Posted May 21, 2012 Report Share Posted May 21, 2012 Its best if you put a cloth round the lever body to stop it flying off as I lost mine in my uni room for ages lol. And a regular bike pump has the end that gets smaller as you pull the lever down to attach to a bike valve. if you get me. Quote Link to comment Share on other sites More sharing options...
Aii_Aitch Posted May 21, 2012 Author Report Share Posted May 21, 2012 (edited) Just got up to 10 bar and the tube slipped off of the threads. -.- This is ridiculous! Surely there is another way of doing it? EDIT: Just did it! yay! Edited May 21, 2012 by Aii_Aitch Quote Link to comment Share on other sites More sharing options...
dann2707 Posted May 21, 2012 Report Share Posted May 21, 2012 How did you do it? Quote Link to comment Share on other sites More sharing options...
Aii_Aitch Posted May 21, 2012 Author Report Share Posted May 21, 2012 Gaffer taped the tube back onto its fitting and used all of my weight on the pump. One more attempt and hopefully it comes all of the way out. Quote Link to comment Share on other sites More sharing options...
Aii_Aitch Posted May 21, 2012 Author Report Share Posted May 21, 2012 Okay, it's stuck half way out and it won't even go the whole way at 160 PSI. Does anyone know if soaking it in meths overnight will release some of the water? Quote Link to comment Share on other sites More sharing options...
dann2707 Posted May 21, 2012 Report Share Posted May 21, 2012 Try poking it out now. Or put it in the oven, Quote Link to comment Share on other sites More sharing options...
Aii_Aitch Posted May 21, 2012 Author Report Share Posted May 21, 2012 Oven it is! Tried poking. It won't budge. The brake was sitting in a garage for a year before i bought it, so it's expanded really far. The water that came out as I was flushing it smelt like gym bags.

Aii_Aitch Posted May 21, 2012 Author Report Share Posted May 21, 2012 It's a shiny metal casing so that wouldn't go down well. :L It'd slowly give me cancer as i rode round town with it or something. Quote Link to comment Share on other sites More sharing options...
Aii_Aitch Posted May 21, 2012 Author Report Share Posted May 21, 2012 So it's out now. It exploded out, so i'm not sure if I collected all of the pieces. Is it just a 2cm long piston and a spring? Quote Link to comment Share on other sites More sharing options...
dann2707 Posted May 21, 2012 Report Share Posted May 21, 2012 That's everything yep. Quote Link to comment Share on other sites More sharing options...
Aii_Aitch Posted May 21, 2012 Author Report Share Posted May 21, 2012 And what do I sand down? I take it that I leave the rubber bit alone because tht's what makes the seal. Should I take that off, or...? Quote Link to comment Share on other sites More sharing options...
Aii_Aitch Posted May 21, 2012 Author Report Share Posted May 21, 2012 All done. Sanded all of the black plastic except the rubbery o-ring thing. Bleeding with mineral oil for now. My water bleeding adventures were short lasted. Quote Link to comment Share on other sites More sharing options...
