Front Disc Brake Kit 74-78 12.19in

The Front Disc Brake Kit 74-78 12.19in by Wilwood is designed for classic muscle cars and performance vehicles from the mid-1970s era, providing a significant upgrade over OEM drum brakes. This kit is ideal for enthusiasts looking to enhance their vehicles for sustained high-performance driving, street racing, or period-correct hot rod builds.

Engineered with a 12.19-inch rotor diameter, this kit balances thermal dissipation and packaging constraints specific to 1974–1978 vehicles. The cast-iron rotors ensure consistent friction coefficients across varying temperature ranges, making them suitable for both street and light track use. The kit's weight of 48 lbs reflects the quality of the cast components and hardware included.

Mechanics and enthusiasts working on 1974–1978 Chevrolet, Pontiac, and related A-body or F-body platforms will find this kit particularly beneficial when upgrading from original equipment or previous conversions. Installation typically requires new brake lines and a suitable master cylinder, often with a bore size of 1 inch or larger, to ensure proper brake bias between front and rear systems.
