14" or 15" wheels?? It makes a difference in prices.
If 14", then go to CARQUEST for parts.
I have a '93 Sunbird with 14" wheels and I, last year, got 2 Rotors, Pads and rear shoes for about $115.00 (the Blue package)
Shop prices vary according to what's involved or discovered. If the Calipers, Master Cylinder, Brake Fluid Reservoir or Sensors are questionable, it could be expensive like $500.00+. Brake Lines can add to the price.
