You may be right and my set were one of the first to come out, new discs etc, the problem has been there from the start. Sadly well past the warranty period now, but hey ho, live and learn! Might disassemble the lever body, have a look for any poor machining finish and polish it up, fit new seals etc. Getting old now and haven't really ridden it since i've been dealing with all these problems, the bike will probably just stay in my garage as wall art 😄
