My bike has a set of Shimano BR-RS505 hydraulic brakes and the rear pad axle, datasheet item 10, just won't budge.
The flathead screw stripped a little when I tried to release it and I didn't go any further.
My first thought was to carefully apply some WD-40 (all I have) into the screw then use a heat gun to hopefully loosen it off.
I've also been told that the only other solution would be using a small hacksaw to cut through the pin!
How should I proceed? Thanks!
(I have also bought replacement, seemingly compatible, hex screws rather than flatheads..)
