Disc Brake Stopping Power at a Great Value

This economical disc brake kit for 1954-1956 Ford cars (including 1955-1957 Thunderbird!) is simple to install and provides big stopping power, at a price nearly the same as replacing your car's original drum brakes. That classic Ford/Mercury doesn't need to suffer from weak, old drum brakes that leave you nervous about driving. Your passengers, you, and your car deserve the confidence of disc brakes and our kit delivers that confidence with exceptional value.

All New Components Designed to Perform

Aftermarket disc brakes are superior to original drums in many ways: more braking force, less brake fade, and easier service. Stopping power starts with our newly manufactured GM Metric D154 style single piston calipers, commonly found on 1978-1988 GM G-Body and A-Body cars. Large 11” diameter, 1” thick vented rotors provide more stopping leverage than common 9” or 10” drum brakes. Brake pads are easier to change than drum shoes, and our brake kit includes a street-friendly organic compound for long rotor/pad life. Replacement pads are common, available from your local auto parts store. Looking for more aggressive stopping power? We carry race-grade D154 disc brake pads that drop in just as easily.

Hardware and Instructions Included for An Easy Installation

Our disc brake conversion kiit includes a detailed, step-by-step instruction sheet with images. The floating calipers include new Grade 5 slider bolts, with all remaining hardware of Grade 8 quality. Cast iron rotors feature a 5x4.5” (Ford/Mopar/AMC) bolt pattern. Plus, this assembly will clear most 15” diameter wheels designed with disc brakes in mind.
