After my muc off bleed incident my brake lever has given up the ghost – no return, holding the pads in place and brake fluid peeing out everywhere. They were Shimano Deore from 2014 Whyte 905. First lever ordered (Shimano Alivio 447) was a right hand lever (despite being packaged as left). Second lever ordered (Shimano Deore M6000) was a left lever but unlike the Alivio doesnt have a hole for the shifter collar to mount into.
Any ideas what I need? This hassle breaks my spirit and determination to do my own maintenance.
