Review on 🔧 ACDelco Professional 18FR1591 Rear Driver Side Disc Brake Caliper Assembly - Remanufactured, Friction Ready, Non-Coated - Shop Now! by Kevin Huot

Can't believe acdelco put their name on this junk! Look at the photos. The pistons in the caliper are rotten and rusting! That's why you replace your brake caliper in the first place. The pistons must be completely flat in order for your pads to slide smoothly when they make contact with the rotor. These "reconditioned" calipers used rotten pistons that only get worse over time (winter and salt only accelerate the corrosion that was already there) and lead to uneven wear on the brake pads. If you have a lifetime warranty on your brake pads, those calipers are useless. No retail store guarantees a misaligned brake pad.
