Danny Kearns Posted August 8, 2007 Report Share Posted August 8, 2007 Right here we go.I have a 2006 Magura hs33 with a Zoo lever blade. Tpa works all good etc. Basiclaly the lever body and blade is about 2-4 weeks old with hardly any riding on it.Now. The brake was pulling in, the pads were moving, hitting the rim, not locking then the lever just stopped moving full stop, like it was that solid it was like a rock.So, i changed the slave cylinders at the back and re-bled it, i actually re-bled it 3 times. The pads didn't move at all. So i thought it was the hosing leaking.So i changed all the hosing, then re-bled it 3 times. The pads still don't move. So i take the lever apart, grease the piston, grease and stretch the spring. Put the lever back together, re-bleed it 3 times. The pads still don't move at all.So changed the actual lever body and all the insides, put it all back together, re-bled it 3 times. The pads still don't move at all. I am seriously concerned about this.I am bleeding with water by the way.Somebody got any crazy idea's around that ?Danny. Quote Link to comment Share on other sites More sharing options...
Joe Papasnap Maher Posted August 8, 2007 Report Share Posted August 8, 2007 I would hazard a guess and say you cant bleed for shit. ( no offence to you inparticular )Air in the system = non moving brake pads.. Quote Link to comment Share on other sites More sharing options...

( no offence to you inparticular )Air in the system = non moving brake pads..To be honest Joe. I think you Bang on there buddy. I don't actually think i can bleed a brake .Think there's a hole in my bleed kit hosing .So do you think thats defiantly the problem ?Danny.

Ash-Kennard Posted August 8, 2007 Report Share Posted August 8, 2007 (edited) you are pulling the lever to the limit, which means there is alot of air in the system, unless you have a gu, then i reckon your best bet would be a bath bleed, take the brake off, undo the bolts, put it underwater, pump the lever so all the air is pushed out, do all the bolts up underwater. job done. refit your brake.EDIT: in 95% sure your bleeding is the problem, as i get exactly this when my brake is leaking, its damn dangerous as the pads will still move to the rim, but wont lock at all some times Edited August 8, 2007 by ash-kennard Quote Link to comment Share on other sites More sharing options...
Dani. Posted August 8, 2007 Report Share Posted August 8, 2007 (edited) Yeah, if your master piston is moving and there is no leak (although the pads would move a bit unless you had a big mother f*cker of a leak) then there's air in the brake, bleed it properly.

downhill_rob2@hotmail.com Posted August 8, 2007 Report Share Posted August 8, 2007 That solid feeling is the piston bottoming out in the piston shaft... meaning the pads wont move any more.. and also meaning your using ALOT of tpa... so did you srew your tpa off when you rebled it? and make sure the piston in the lever was pushed right back out? (way to the that is connect bleed kit to slave cylinder whilst still leaving the bleed bolt in the lever, then push some water in, and it will push piston right back out to the lever blade...) then try rebleed it then?

Mat Smith! Posted August 8, 2007 Report Share Posted August 8, 2007 Try it without the deng blade on, every brake ive been on with them on have pulled to the bar, or might as well have.Matx Quote Link to comment Share on other sites More sharing options...
Danny Kearns Posted August 8, 2007 Author Report Share Posted August 8, 2007 Right just to sort things out.I bath bled it, found the tiny hole ever that air was creeping on of. So i changed the main hose with another one. Bath bled it again, working amazing.The lever pulls in and hit the rim, only pulls in a little bit, holds, bites and locks like anything. Has an amazingly loud honk to it also.The brake isn't spongy either.All that hassle from a tiny hole.Got the best brake ive ever used now .Zoo pads on a smooth for the win.Thanks for all the help, appreciate it loads.Danny xx Quote Link to comment Share on other sites More sharing options...
