This 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. That Ford rear end handles the power to make it go, but these binders clamp down when you say whoa! Today’s average family sedan can stop from 60 MPH in 120 feet, at nearly 1G of deceleration. You need the same stopping power. 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, commonly found on 1978-88 GM G-Body and A-Body cars. Large 11-1/4” 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.
This disc brake kit fits Ford 8 inch axles, as well as passenger car Ford 9 inch axle housings with “big bearing” ends (3.150” O.D. bearing, found on passenger cars from 1974-79). Included bracketry will adapt this kit to both “new style” and “old style” Ford 9 inch housing flanges with the 3/8” bearing retainer bolt holes. 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. Plus, this assembly will clear most 15” diameter wheels designed with disc brakes in mind. Note that there are no provisions for a parking brake, making this the perfect disc brake conversion kit for the budget-focused builder who prefers a basic upgrade kit.
This line kit would be used to connect from "hard" lines on the rear axle to rear disc calipers when changing from drum to disc brakes. DOT approved brake line kits include two stainless steel -3 AN brake lines with the banjo fitting installed, banjo bolts and washers, 3/8"-24 IFF frame adapter fittings and frame tabs with clips. Includes -3 AN fittings and adapters to connect them to 3/16" brake line using a 3/8"-24 IFM flare nut.
This kit will NOT work on pickup housings or the 50's 9" housings as they only have about 2" backspace. The exception would be the late 50's station wagon rear ends.
When using with a Currie Axle with an o/d register of 2.795", the rotor is included in this kit with an i/d register of 2.78" and therefore will need to be machined by increasing the hole diameter in the rotor to match the Currie axle spec of 2.795"
