My passenger front brake is locked up. I have tried to free it, but I think it is just rusted to bad. How do I replace the caliper? I bought a new one and there are no bolt holes to be seen on this new one...which is odd to me? How does it stay on?

 

On the top and bottom of the caliper are two grooves. The retainers are two pieces of metal with a rubber strip molded between them. Trick is to squeeze the metal together compressing the rubber and push it out of these grooves. I took a chisel and ground a V in the end, place against these retainers and as you strike the chisel the V notch compresses the metal and mooves the retainers, continue removing the retainer with a straight punch.
