This is a tool to retract the brake caliper piston on various Volvo and Ford cars.
Use with a 30mm socket apply pressure (approx 20Kg / 200N required) while turning clockwise to get the caliper to retract .
Requires two M3 hex head bolts for the pins (approx 20mm long). Screw them in, but leave them a few mm proud for a better fit.
I printed in PLA @ 30% infill.
