So I am trying to change brake pads
I have a Giant Roam 2 disc of 2013 vintage with Tektro brakes.
That 3mm retaining pin on the caliper that needs to be removed is frozen in place and I have managed to strip the screw head so that my 3mm hex wrench spins freely inside.
How do I get out of this corner I have painted myself into? I thought of jamming a 3.5 hex wrench in there, also applying heat...but I have a propensity to make bad situations worse. I soaked it in solvent last night, but without being able to grip the screw head, I’m not making progress.
Thought I would seek guidance here before employing the bigger hammer.
