Rockman Posted March 15, 2012 Report Share Posted March 15, 2012 Right, this is proper p*ssing me off. Brake was all good, then suddenly stopped working, so I changed from LGM's to Bealeys, these worked for a bit, then was suddenly terrible, so I changed to Rockpads, all good, then suddenly, stopped working.. finally changed to Heatsink Yellow's, all good for a while.. then again these stopped working! I have grinded my rim, changed clamps, had a booster on/off, 2 finger lever, 4 finger lever, but I can not get my brake to work. It doesn't have any bite, any hold, and is completely silent, WTF IS WRONG? Echo Pure frame Echo TR clamps Magura HS33 2005 Rockman Single Wall If that helps. Thanks Shane.

trialsbeginner Posted March 15, 2012 Report Share Posted March 15, 2012 tried giving it a new bleed? Quote Link to comment Share on other sites More sharing options...
Martin Reynolds Posted March 15, 2012 Report Share Posted March 15, 2012 Sounds like your pads/rim are getting contaminated, explaining why when you change your pads, they work for a while then go shit Quote Link to comment Share on other sites More sharing options...
Rockman Posted March 15, 2012 Author Report Share Posted March 15, 2012 I'll try a bleed. How are they getting contaminated? I keep all oil away from them and have never spilt any fluid on my rim/pads. Quote Link to comment Share on other sites More sharing options...

I keep all oil away from them and have never spilt any fluid on my rim/pads. It could be anything, brakes leaking slightly? Water? Rain? ive seen it before where someone keeping their bike in a humid shed effected their brake. Quote Link to comment Share on other sites More sharing options...
Ali C Posted March 15, 2012 Report Share Posted March 15, 2012 Have you had any punctures recently? When you take your tyre off and put it back on you generally get some release agent from the tyre on your rim, which basically makes your brake go dick.

Rockman Posted March 15, 2012 Author Report Share Posted March 15, 2012 Maybe leaking, never had it out in the rain. It's kept in the house in a warm room. Haven't had any punctures for months. Quote Link to comment Share on other sites More sharing options...
Topsy Posted March 15, 2012 Report Share Posted March 15, 2012 (edited) I've got exactly the same problem since quite a long time. And nothings contaminated or anything suggested above. Wondering if a new rim would help?.. Edited March 16, 2012 by Hopping_Topsy Quote Link to comment Share on other sites More sharing options...
Rockman Posted March 15, 2012 Author Report Share Posted March 15, 2012 I've got exactly the same problem since quite a long time. back-ache -.-) And nothings contaminated or anything suggested above. Wondering if a new rim would help?.. Starting to think, new wheel, brake, and pads, because I really can't be arsed with this. Quote Link to comment Share on other sites More sharing options...
howvard Posted March 16, 2012 Report Share Posted March 16, 2012 My rear brake has.... we'll say enough hold, and is compleley silent, and i love not have the sound there, makes everything seem so much smoother. (But i still have bite soooo dunno what to say) have u ever tried running two different types of pad, a hard and soft compund, work a treat for me on a smooth rim Quote Link to comment Share on other sites More sharing options...
williams Posted March 16, 2012 Report Share Posted March 16, 2012 Yoo, I have the same problem here to! I've started with rockman blues, they where perfect and then they got BAD. I Re-grinded my rims and bought new pads (Heatsink yellows) still preatty sound less without any remarkable hold, and only a small sound. Im probably going to get a new rim...

ashleys sugden Posted March 16, 2012 Report Share Posted March 16, 2012 pads set up square? the rim may be to thin for the brake pads to bite the rim, or the TPA on your lever has stoped working so you cant ajust the brake while riding.or one barke cylinder may be working more than the other one Quote Link to comment Share on other sites More sharing options...

Carlperkins Posted March 16, 2012 Report Share Posted March 16, 2012 Sounds like contaminated pads to me too. Id usually say re-grind rim, sand pads, re-bleed brake and set up again but if thats not working, it could be your setup maybe? Have your slaves been pushed out slightly or no longer square? Or if your rims at an angle and youve had the pads out... Have you put them in upside down? Not saying you dont know how to maintain your bike, just listing off stuff cos it seems like a weird situation. Quote Link to comment Share on other sites More sharing options...
