Repair or configure the rear disc-brake system of your 1982–1992 Pontiac Firebird, Formula or Trans Am with replacement brake-caliper backing plates. These application-specific plates support the rear caliper and related brake components on selected third-generation F-body axle and brake configurations.

Current selections include newly machined 1LE backing plates for 9-bolt rear axles and 1990–1992 10-bolt rear axles. Dana 44 backing plates designed for PBR rear calipers are also available. Depending on the product, driver-side, passenger-side or paired configurations may be selected.
