anzo Posted December 7, 2005 Report Share Posted December 7, 2005 Evenin All! I recently removed both magura brakes from my t-pro (05 frame, 05 brakes) and gave them a good clean after riding in some shitty weather. All in good condition however I noticed that one of the pistons was sticking, so I gave it a bit of a spray with silicon but no help, so after reading up on here I decided to bleed them and fill the system with water because it was worth a try (with the input on this forum) so try it I did...it worked, but the pistol STILL sticks. I'm sure its a common problem, see it will come out occasionally, but not go back in unless I press the other piston in and level them out manually, and then it sticks again and again. So thats problem number one, a sticking piston, as for problem numero...two...I fitted the brakes, and my brakeS (yes, both of them) had a 'lock on', 'metal against metal', 'wont budge' feel, and the TPA didn't move at all, even when I took the lever off...assuming now that the TPA thread is will and truely screwed (no pun intended) however, after a wee bit of research I cant seem to find replacement magura levers, I can only find 120 quid magura compatable ones, not the original ones, not that I would mind paying 120 for the levers, but its nearly Christmas and I can do without the cost at the minute. A bit pee'd off because now my brakes are rubbish (whereas they used to lock on with a smooth rim and tar, but now with a grinded rim, tar and a booster, they seem to have gone worse then better.) All advice, opinions, help, abuse greatly appricated! Quote Link to comment Share on other sites More sharing options...
mat hudson Posted December 7, 2005 Report Share Posted December 7, 2005 its really nice to see such a well structured, well spelt first post from a new member. :) i would have thought the sticky piston could be sorted by pumping the brake lever whilst spraying a thin lube (GT85 or WD40) onto the piston body. if this doesnt work, you may well need to take the piston out completley, and replace it with a new one. B) on the tpa topic, have a search around the forum for a tpa bodge, i think its been explained close to 400 times. :) good luck :D mat Quote Link to comment Share on other sites More sharing options...
Mark W Posted December 7, 2005 Report Share Posted December 7, 2005 For the pistons, you may need 3 hands :) You've basically gotta press the lever in so the pistons are pushed out, but you need to keep a finger over the non-sticking one so it forces the sticking one out further. When it's done this, spray some GT-85 or similar on there. Release the lever, pump it a few times, then squeeze the lever whilst covering the non-sticking piston again. Use a rag/bit of tissue to clean off the piston, and spray with GT-85 again. Repeat a few times, cleaning it each time, then just spray it with GT-85 and leave it. Doing that for both is a good call just 'cos it'll help keep 'em all clean 'n' fresh, but you only have to do it on the sticking one for now, really.

Si-man Posted December 7, 2005 Report Share Posted December 7, 2005 Just use a belt etc for the "3rd hand£ you need, works a treat :) Quote Link to comment Share on other sites More sharing options...
anzo Posted December 7, 2005 Author Report Share Posted December 7, 2005 Okie Dokie, I'll try that when I'm home (stuck at work now). Any ideas for getting hold of cheaper levers then the carbon fibre ones I saw (supercycles)? No shop seems to stock them around here (Derby). How do I get the piston out? :) Thanks all!

Dr. Nick Riviera Posted December 7, 2005 Report Share Posted December 7, 2005 i think the idea is you replace the whole cylinder , which is a case of removing the hosing , attatching the new one and re-bleeding the brake. p.s. this guy for teh validated Quote Link to comment Share on other sites More sharing options...

Mark W Posted December 7, 2005 Report Share Posted December 7, 2005 Where? :) I'm no expert, but the range of Magura levers here might be what he's talking about? They've got the whole range of Magura levers, 'cept for the ultra old shit ones... Quote Link to comment Share on other sites More sharing options...

That is unless I'm mistaken, I bought the bike in about September 05 (brand spanking new) , so I imagine it is fitted with 05 mags? Please correct me if I'm wrong. parts ordered now, many thanks.
