RyanRs Posted April 21, 2005 Report Share Posted April 21, 2005 My magura caliper piston ( the NON slave side ) has recently decided to start sticking. When i apply the brake and release, it all works freely and the slave side returns nicely, but the non slave side stays out. it doesnt even think about returning back. how do i stop this as it is really bloddy anoying, because the pad catches the tar on my rim and makes anoying noises!!

Impacted. Posted April 21, 2005 Report Share Posted April 21, 2005 Yeah, this happened to me sort of, not quite as bad as competely "sticking" but it would return alot slower, I sprayed WD40 on it a few times at different occasions and it worked better after that.

RyanRs Posted April 21, 2005 Author Report Share Posted April 21, 2005 Kool, cheers peeps! i have just adapted my rb blade to fit my hs33 body and changed the levers over. the caliper piston appears to be working a bit better now! maybe it had something to do with the rb piston?? i have bodged hope seals in my rb + insulating tape. it 90% stops it leaking but i have to lube then pump the lever for 5 min every morning to get the thing to work, as the seals are too big and make the piston return Super slow. i have been putting a bit of 'Automatic Transmision Fluid' (lol) -as it is the only lub'ey stuff i have, on the white piston part of the rb (the external part where the adjuster goes) then pumping it to work the lube in. works fine after that (as long as i don't leave the lever without being pulled for more than 20 min!) but the hassle of it all is too much! so i changed the blade to the hs33. I think i will service the calipers tomorrow and give it a fresh bleed. How do you get the caliper pistons out?? Also, i have herd that using de-ionized water is better than normal water....? Doesn't De-Humidifiers create de-ionized water?? as i have 2 of them in my home! Thanx Ry :- Quote Link to comment Share on other sites More sharing options...
JT! Posted April 21, 2005 Report Share Posted April 21, 2005 (edited) This works: Tryed and tested. Have non or little on your TPA. Ajust the brakes so that you dont have any, or the tiniest little bit. That way they will both retract. I can guarente that will work. Re-bleeding it wont do anything, cleaning the pistons might. :- Edited April 21, 2005 by JT! Quote Link to comment Share on other sites More sharing options...
