J.C. Whitney JJ27150002 Front Left Brake Caliper New Natural Finish Without Brackets

Delivered in a natural, uncoated finish, this single-piston caliper is sold without mounting brackets, making it ideal for applications where existing hardware is being reused.

Built to match original equipment specifications, this caliper restores proper hydraulic clamping force to your disc brake system, helping maintain consistent pedal feel and reliable stopping performance. The phenolic piston resists heat transfer to brake fluid, reducing the risk of vapor lock and brake fade under demanding conditions.
