You have 1 more chance === Try a BIGGER Allen Bit and hammer it in. Then turn it loose. Also spray WD40 to loosen any old road rust
or use bigger TORX bit and hammer it in, so that it is stuck hard on the bolt, then you have 1 chance to loosen it. Then throw it away.
I really recommend stainless pin FIRST before doing that , because you don’t want to re-use that damaged pin again (they used bad steel).
Stainless Steel Brake Caliper Pin (x1) (Pad Retaining Bolt Axle) :: Hyosung GV125-S EFi

Long Bolt = It is a pin for the brake pad.
“Little Screw” = it is to stop the long bolt from falling out, it is required on all Hyosung machines.
Hyosung GV125-S from factory uses “Little Screw (grub Screw”) ==> Long Bolt (Caliper Pin) = Both of these 2 go inside the caliper.
Maybe yours is missing a “little screw” , that is why we send you stainless.
You will now need a long bolt “Caliper Pin” like the link i posted above ^ because the old parts show be thrown away after fighting to remove it (They will be worthless as i can see in first picture above ^ you will not use those parts again and upograde to stainless steel
Make sure to buy “COPPER GREASE” for pistons , screws , and the RED section of your brake pads, they will stop them getting stuck , next time you do maintenance
Hope this helps

Hi Marcel, thanks for the advice, it works the pin on the back wasn’t damaged so I was able to unscrew it without problems I had a small problem with the “little screw” when I tried to screw it and the entry hole broke so I tried to redo the thread with a larger one I’ll have to get a new calipter

Hey, I am sorry about that. Are you sure it is safe to ride like that ? I see a crack in the picture?
Brakes are important, I would not want you on A&E 🚑 if the caliper locks up at high speed or pads fly away, the little screw was to stop the pin from rattling out (It has happend to me before on my GT, but luckily the caliper had 2 pins, so i was able to ride slowly and order new stainless pins & new screws. I always made sure to check my calipers. This is a very bumpy country!) -

I did a couple of tests though I’ll order one now Meanwhile the motorbike is stopped for now Do you know where I could find them?
I could not find one to order yet (out of stock from Hyosung Korea until they make more) , but fix your email please and message me. I will try to get an aftermarket caliper for you that could fit , you could try it.
Ride safe, lots of rain & wind coming this weekend!
