Hey guys i need some help. Just bought my first dirt bike for cheap. It's a 93 kx 125 that I picked up for $600. It's in decent shape but it's missing the rear brake caliper assembly. I ordered one off eBay for the exact year and model that I own. My question is, how in the hell does the caliper go on? It's a two piece caliper. One piece is where the pads go and the other piece looks like a bracket with screw holes. I can't seem to figure out where the bracket bolts on to since there are no screw holes to attach it to. Does it bolt on to the rotor? Do I have the wrong caliper assembly? Please help. Thanks .
