Reply To: Issue with brake caliper pin – GV125 S EFi (Aquila 125)
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
