Rear Disc Brake Kit

The ALLSTAR PERFORMANCE Rear Disc Brake Kit (ALL 42019) is an essential upgrade for performance and street vehicles requiring reliable stopping power and consistent braking feel. This kit addresses a critical performance gap in many classic and modified vehicles where original drum brakes or outdated brake systems limit both safety and driving confidence. Whether you're building a dedicated track car, restoring a muscle car, or upgrading a street rod, a quality rear disc conversion delivers the thermal stability and modulation that hydraulic drum systems cannot match.

This rear disc brake kit features engineered cast iron rotors and high-performance caliper assemblies designed to manage heat dissipation more effectively than traditional drum setups, reducing fade during aggressive driving or repeated hard stops. The kit's balanced caliper design ensures even pad wear and predictable stopping force, while the larger swept area increases friction surface and improves pedal modulation. ALLSTAR PERFORMANCE has engineered this assembly with OEM-quality construction standards, delivering repeatable stopping distances across a wide range of ambient temperatures and driving conditions—critical for both street and circuit applications.

This rear disc brake kit is ideal for hot rodders, vintage muscle car enthusiasts, and performance builders who demand superior braking response without compromising vehicle dynamics. Installation typically requires basic mechanical knowledge and common hand tools; the compact assembly (12.5 x 5.6 x 12.5 inches) fits most standard rear axle housings. Verify rear brake line compatibility and caliper bracket fitment with your specific vehicle platform before ordering to ensure seamless integration with your existing hydraulic system and suspension geometry.
