Gorilla Brakes Semi-Metallic Disc Brake Pads are designed to restore smooth, predictable braking to classic Hayes HFX and MX-1 brake systems. Using a soft semi-metallic compound, these pads deliver quiet operation, fast bedding-in, and rotor-friendly performance for trail riding, recreational MTB, and everyday use.
