Greetings Posted August 31, 2007 Report Share Posted August 31, 2007 Is there anything I can do to stop the slave piston from seizing? Due to the dry weather and dust accumulating near the seals, the piston just doesn't come back when you release the lever. It helps when you lube it with silicone grease but it only lasts about 6 hours of riding, then you have to do it again The brake is running on water which is probably the cause of this problem.Any ideas?

scousertrials Posted August 31, 2007 Report Share Posted August 31, 2007 use car brake cleaner when the pistons are fully out when the lever is pressed.And the polish version:uzyj srodka do czyszczenia hamulcow gdy tloki sa maksymalnie na zewnatrz w czasie gdy raczki hamulcow sa wcisniete.

Ash-Kennard Posted August 31, 2007 Report Share Posted August 31, 2007 pull it out with some plyers/molegrips as far as it will go then just lube it with some thick oil/grease Quote Link to comment Share on other sites More sharing options...
Greetings Posted August 31, 2007 Author Report Share Posted August 31, 2007 use car brake cleaner when the pistons are fully out when the lever is pressed.Will try that out.Good translation by the way but it wasn't necessary pull it out with some plyers/molegrips as far as it will go then just lube it with some thick oil/greaseThat's what I've been doing so far, unfortunately the grease doesn't last long and causes dirt to accumulate behind the backings. Might have to try a different kind of grease though I remember Tart writing that the silicone stuff is the best for this purpose. How about graphite?

Ash-Kennard Posted August 31, 2007 Report Share Posted August 31, 2007 i personally used motor oil because it was laying around. but it could also just be your bleed, so try both IMO Quote Link to comment Share on other sites More sharing options...
omgnoseat Posted August 31, 2007 Report Share Posted August 31, 2007 I'm having the exact same problem I don't have any oil or anything, so this might be a stupid question, could you use wd40 aswell? Quote Link to comment Share on other sites More sharing options...

Surely you have some motor oil in your garage? Quote Link to comment Share on other sites More sharing options...

Surely you have some motor oil in your garage?Well we don't even have a garage, just a shed I'm a mechanical noob, but i'll ask my dad to bring some from his work.And yea I used to run DD, but the magura marta wasn't holding up enough, and I'm too poor to get a hope so I was kinda forced to go hs33.Still prefer DD though Quote Link to comment Share on other sites More sharing options...
dave33 Posted September 1, 2007 Report Share Posted September 1, 2007 this happend to me a while ago when i goy my bike really muddy, problem is the dirt thats what makes it stick, just take you brake apart and give it a really good clean in hot soapy wateri re bleed mine to at the same time also with water can use a track pump to get the piston out so you can clean Quote Link to comment Share on other sites More sharing options...
