grub

Assume gear lever was worn, purchased new one, shaft also worn :( would it be ok to weld for now? I assume it's engine out and strip etc ? Any other ideas ? Could I drill through pedal and shaft tap it then add grub screw ? What options do I have Tia Sent from my iPhone using Tapatalk

Morning all, My front brake caliper has two grub screws covering the brake pad retaining pins. These little screws will not budge. Penetrating oil, hammer and punch, and heat have all failed. Just wondering if anyone has a suggestion before I get the drill out? Griff.
