Purchased in June 2017. In early 2018 the car showed signs of caliper deflection (pedal vibration). In March 2018, a safety check revealed extremely uneven lining wear and deformed rotors. These calipers failed after a few months of brief use. Pistons will bind and not retract properly, causing excessive wear and heat. Lousy calipers were pulling out the rotors due to excessive heat, causing the rotors to warp. Very dissatisfied with this product.
