laurent Posted November 14, 2020 Report Share Posted November 14, 2020 Hi everyone ! I bought from you a few years ago a "Hope tech evo" lever (https://ep1.pinkbike.org/p4pb9311179/p4pb9311179.jpg). For a few weeks, maybe a month it leaks some break fluid from the two reservoir "caps" . Having some spare diaphragms, i tried to change them. And it still leaks. Not a lot, the break is useable. But it does worry my in term of reliability. Anyway, what do you think of it, it is a known issue ? And what spare part could i swap/change to solve this issue. Thanks a lot !

Cap Posted November 14, 2020 Report Share Posted November 14, 2020 If it is just out of the small hole in the cap then it is normal for all brakes, it's just excess fluid that is on top of the diaphragm. Any pictures or videos of the leak? Quote Link to comment Share on other sites More sharing options...
laurent Posted November 14, 2020 Author Report Share Posted November 14, 2020 You mean excess of fluid from the bleeding (after changing the diaphragms) ? Or it could be fluid coming from the reservoir (inside) ? I will take some pictures, but the leak is small and "slow". Quote Link to comment Share on other sites More sharing options...
Cap Posted November 15, 2020 Report Share Posted November 15, 2020 On new brakes it's excess fluid from the bleeding procedure. If it's a small amount of fluid and it doesn't mess with the brake I would just wipe it off and carry on using it and see if it stops.

laurent Posted November 16, 2020 Author Report Share Posted November 16, 2020 It is a small amount. If i wipe it off before riding, general usually it's not there again after that. But if y let the bike stays stored a few days there is a small amount of fluid again. See on the picture attached, it seems to come from around the screw holding the caps .... hence the rust ... I ride it like that for weeks now, but if there is a problem i'd like to know and fix it. And if there is no problem, i much more happy then ! ;-) Quote Link to comment Share on other sites More sharing options...
