Disc Brake Conversion Kits

Disc Brake Conversion Guide

Classic Performance Products (CPP) has been the trusted name in disc brake conversion kits for classic cars and trucks since 1991. Our disc brake conversion kits are built for builders, restorers, and performance enthusiasts who demand modern stopping power without sacrificing the character of their classic vehicles. Whether you are upgrading a daily driver or building a show-quality restoration, CPP has the right kit to convert drum brakes to disc brakes with a direct fit and ... proven performance.


Why Upgrade from Drum Brakes to Disc Brakes

Factory drum brakes were standard for decades, but they cannot match the braking efficiency, heat control, and safety of modern disc brakes. Our drum to disc brake conversion kits deliver shorter stopping distances, better performance in wet conditions, reduced brake fade under hard use, and lower long-term maintenance. For rear axles, a rear drum to disc brake conversion kit adds balanced braking and improves vehicle control under heavy loads or high speeds.

What’s in a CPP Brake Conversion Kit

Every CPP brake kit is built to install with minimal modification. Depending on the application, kits may include: Machined rotors in standard or drilled and slotted designs - OEM-style or performance calipers in multiple finishes, with integrated parking brake options - Master cylinder and power brake booster assemblies for improved pedal feel - Spindles, mounting brackets, bearings, seals, and all necessary hardware - Stainless steel or OEM-style rubber brake hoses - Detailed installation instructions for a direct bolt-on fit
