scotty Posted December 27, 2022 Report Share Posted December 27, 2022 Well after a good few months sat in the shed both my Trialtech levers aren't returning after they are pulled. Planning to bleed them in the next couple of days but was wondering if there is much that can be done with the pistons etc. if the bleed doesn't solve it? that's assuming its the levers that's the problem. I tried a search but couldn't see much info Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted December 27, 2022 Report Share Posted December 27, 2022 Try a drop of chain lube on the piston. Quote Link to comment Share on other sites More sharing options...

robkerly Posted December 28, 2022 Report Share Posted December 28, 2022 (edited) chain lube may or may not work long term as some types are designed to go sticky to stay on a chain. pesonally would avoid just in case. silicone spray lube or silicone grease is safe on the rubber piston seal and wont turn to glue. fork seal grease is fine if you have some, but its expensive so dont buy it specially for your levers. best of luck. honk Edited December 28, 2022 by robkerly 1 Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted December 29, 2022 Report Share Posted December 29, 2022 Muc off wet lube ( chain oil ) is what I’ve always used. 1 Quote Link to comment Share on other sites More sharing options...
The dab Posted December 29, 2022 Report Share Posted December 29, 2022 Do they still have the alloy pistons in? water bleed or mineral oil? Oil as said should help on the pistons and also check the slaves Quote Link to comment Share on other sites More sharing options...
Chakers1998 Posted December 29, 2022 Report Share Posted December 29, 2022 Silicone grease is the one for me. Also, give the spring a little stretch as if you're playing an accordion. Quote Link to comment Share on other sites More sharing options...

DYAKOV Posted December 30, 2022 Report Share Posted December 30, 2022 No alloy pistons on those levers. Even though there are ones that you can use, guys from trialtech recommended me to stick to the plastic ones (I’d enquired on that before). Best bet is to change the o-rings and see if that helps and if not, then just get a new set of pistons. Quote Link to comment Share on other sites More sharing options...
DYAKOV Posted December 30, 2022 Report Share Posted December 30, 2022 Also, they don’t have to be the carthy pistons, if you want to save a few quid the standard ones will work just fine (personally, I’d opt for the carthy ones cos otherwise you’re essentially running a standard trialtech lever setup) Quote Link to comment Share on other sites More sharing options...
The dab Posted December 31, 2022 Report Share Posted December 31, 2022 If it’s the levers ross sold then they should have alloy pistons as they are my old ones. worst levers I ever had on a bike Quote Link to comment Share on other sites More sharing options...
scotty Posted January 1, 2023 Author Report Share Posted January 1, 2023 Well, fresh bleed with some trialtech fluid and a bit of oil on the piston and both levers are like a dream again! First time I've used the top bleed too, I must have got used to shit brakes over the years. Cheers for the advice all 1 Quote Link to comment Share on other sites More sharing options...
