Value-Packed, Complete Disc Brake Solution. This complete, yet economical disc brake kit for Ford 9 inch and 8 Inch axles is simple to install and provides big stopping power, at a price nearly the same as replacing original drum brakes.

Your passengers, you and your car deserve the confidence of disc brakes and our kit delivers that confidence with exceptional value. 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 with a 2.5 bore size. The integrated emergency brake lever makes parking brake setup a breeze for any vehicle. These calipers were originally found on 1979-85 GM E-Bodies (Eldorado/Riviera/Toronado) and 1980-85 GM K-Bodies (Cadillac Seville).
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 sized, 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. Rubber flex lines with matching banjo bolts, e-brake cables and frame tabs/clips are included to finish out the installation. Fits Ford 9 Inch and 8 Inch Housings.

Bracket spacers are also included, allowing this kit to work with axle flange offsets of 2-3/8" or 2-1/2" common on Ford 9 inch passenger car rear ends. Axle flange offset is measured from the axle housing flange face (with bearing retainer removed) to the axle shaft flange face (side where the brake rotor/drum rides, including the thickness of the axle flange). Kit 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 dual bolt pattern in 5x4.5" (Ford/Mopar/AMC) or 5x4.75" (Chevy/GM) to match your desired wheel hub pattern.

Brake rotor has a 2.78" center hole and works with axle shaft flanges no larger than 6-1/8" diameter. If your axle shaft flange exceeds that diameter, you will need machine the flange to decrease the diameter. Brackets position the calipers in a rear-mid orientation (3 o'clock on the driver side rear wheel), making this ideal for pull-type emergency brake cable systems (most OEM systems work in this way).

2.36" - 2.50". By shoprat on November 26, 2021. All fit well with little modification and seam to be quality parts. Yes, I recommend this product. Disc brake kit & axle pads. By Fun Car on September 04, 2021. I'll either narrow the axle pads or make a new set - no big deal! Axle pads 2-1/2", need 2" - my error!
Calipers should be coated to prevent corrosion. Axle pads very well constructed. By Joey on June 24, 2021.
By None on June 14, 2021. Basic kit is nicely matched, but needs t-bolts added, stock ones aren't long enough to safely hold brackets My axles had 1/2 studs. With custom wheels, you will need longer than oem studs and these are lug centric rotors that will have to be drilled out to fit over lug shoulders.
Lug holes precision is very poor. Nearly all axle flanges will need trimming. New correct length T-bolts aren't provided. Rotor lug holes aren't sized properly. Rotors are cut, not ground.
By Jdm on March 05, 2021. Rotor bore did not fit axle flange, was able to enlarge and complete the installation. Related Items / Suggested Parts.
