I have the clean t13 v2 brake lever with echo calipers. I can't get the pistons to retract consistently. I've bled them several times, lubed and exercised the pistons but still can't get them to work right. Has anyone else had this issue? Thanks for the help!
Wondering if anyone has researched and or successfully converted some sort of non trials mtb 26" frame to a streety trials bike. Something with a long-ish top tube, 0drop bb or so, short stays, low front end like 60-80mm fork and rear disc.
