Equipped with two phenolic pistons measuring 51.05 mm in diameter, this caliper helps reduce heat transfer to the brake fluid, minimizing the risk of brake fade under normal driving conditions. The inclusion of caliper slides and a mounting bracket facilitates proper installation and operation, while the gray finish maintains a factory-correct look.
