Ben Swales Posted July 23, 2006 Report Share Posted July 23, 2006 (edited) i'm having some real trouble with my rear magura, every time i pull the lever, the pistons either return REALLY slowly, or don't return at all, and are REALLY hard to push back...i've tried re-bleeding the brake four or five times, with water/antifreeze, incase there was air in the system and it's still happening i've tried everything i can think of, including cleaning the pistons with degreaser when they're extended, removing the lever blade and cleaning inside where the TPA goes with degreaser, but nothing seems to help! my knowledge of maguras is admittedly limited, i tend to just fit them and forget them.my setup is a 2004 HS33, with fresh products lever blade (tried re-fitting the old lever blade and the problem's still there), hope braided hosing and it's bled with water/antifreeze.i'd really appreciate any input/advice on this, as it's doin my head in! also, i'm supposed to be goin ridin later today so speedy replies would be great!! also, it's been transported on a plane a couple of weeks ago and not ridden since, not sure if that might afect it, shouldn't do right?my msn is yfrontsonmyhead@hotmail.com if people want to add me, a it'd be loads easier through that Edited July 23, 2006 by BenS Quote Link to comment Share on other sites More sharing options...
Lee Cable Posted July 23, 2006 Report Share Posted July 23, 2006 Have you tried lubing the pistons? I dont actually have a magura, but from what i read on here, its either your pistons not being lubed. Or its your lever body Quote Link to comment Share on other sites More sharing options...

Bondy Posted July 24, 2006 Report Share Posted July 24, 2006 mine did this a couple of days ago, also i think due to the heat, its working better now, all i did was fiddle about with the lever and it worked fine(ish) Quote Link to comment Share on other sites More sharing options...
Mark W Posted July 24, 2006 Report Share Posted July 24, 2006 To be honest, I haven't had any trouble with mine. I guess it may be the heat affecting the seals, but people use them in warm countries without trouble too so perhaps not? Quote Link to comment Share on other sites More sharing options...
JT! Posted July 24, 2006 Report Share Posted July 24, 2006 hmm, really does seem the heats affecting the seals? my monoshite(trial) isnt reacting very well, and my hayes stopped working altogther!best solution, get a v brake No matter how many times you say 'get a v-brake' no one ever will.Becuase they're shit!Mine did this a few days ago. Do the pads retract well when there's no or very little tpa on?I lubed up my pistons (all 3, don't forget about the one in the leaver) and it was fine.

Mark W Posted July 24, 2006 Report Share Posted July 24, 2006 Lubing's generally done me fine too.Quote away, you bastards.Ben - you said you cleaned them with degreaser; did you actually regrease them afterwards? Quote Link to comment Share on other sites More sharing options...
