You can check Alldata.com for any, but it's doubtful you'd get far on a 1991 vehicle with GM.

These W body rear brakes are pesky and a PITA. Many times the calipers seize and have to be replaced.

The reason they seize is the parking brake mechanism. when you engage the parking brake it pulls a lever that turns a screw to engage the piston. When the screw get corroded it freezes. Fix: pull the caliper and soak in oil overnight. Put the parking brake lever in a vise and start to turn it back and forth. eventually it will free itself untill you get about 3/4 of a turn. keep working it untill it moves freely and apply plenty or brake lube..Note!: do not turn it all the way in or you can pop out the piston..Note!: try to use the parking brake regularly to keep everything moving freely and avoid problems in the future
