I tried to perform this swap on my MY98 Impreza RS. Everything went accordingly until I got to the caliper brackets. I could not get one of those bolts with the dust boot and flange style head to come out of my WRX brakets so I could put the one out of the RS brakets in place of it. I did attempt to install the WRX brakets without switching the bolts out but it caused my brake pedal to have no pressure. Please help.
