If you have a 91, I assume you have PBR's. If that's the case, use a C-clamp and push the piston straight in.

82-88 cars were equipped with iron Delco-Moraine calipers and 10.5" rotors. 89+ had alum (PBR's) and 11.7" rotors.

if you fixed your issue then disreguard, just did my brakes yesterday and had the same issue, how ever I researched it in a book and apparently you need to put a brake tool (to compress the piston in) while in place remove the parking brake lever then the piston will compress in, after it is in enough for you, put the parking brake lever about 1/8 inch from the stop on the caliper, and you should be good.
