So today the one of brake wires snapped near the lever, so to repair it I purchased a new wire (as the housing ect. looked fine) and began the replacement.
It was all going well, until it came to change the fixing bolt unit from the old wire to the new. I cannot for the life of me get the top nut to turn. (It is for a Shimano Nexus Roller brake)
As a student I have only limited tools so what I have tried is drowning it in WD-40, then used pliers to hold the body and used a wrench to turn the nut. But to no avail.
Could anyone provide me with some tips on how to solve this?
Thanks in advance!
