Part # 91664083 Condition New Brand Speedway Motors Sold Kit Details Info 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. 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. Superior to Drum Brakes 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 This rear disc brake kit fits Ford 8” 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). Hardware and Instructions Included 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. Disc brake stopping power at nearly the same cost as rebuilding/replacing drum brakes 11” diameter, 1” thick vented cast iron rotors dissipate heat faster than drum brakes Serviceable design ensures good drivability and piece-of-mind when on the road Street-friendly GM D154 style pads, replacements available nearly everywhere GM “Metric” style single piston calipers with 7/16-20 banjo-style inlets Integrated parking brake for a feature-complete brake system Brackets position the caliper in a rear-mid orientation, ideal for pull-type E-brake cables Fits Ford “big bearing” 9 inch housings from passenger cars and 8 inch rear ends Use with Ford 9 inch rear ends with 2-3/8” or 2-1/2” axle flange-to-housing offsets Dual wheel bolt patterns covering all GM/Ford/Mopar GM Stud Pattern: 5x4.75" w/ 7/16" Studs Mopar/Ford Stud Pattern: 5x4.5" w/ 7/16 Studs (Will Need to be drilled out for use with 1/2" studs) Use with 15” or larger disc brake-style wheels Easy bolt-on installation w/ included instruction sheet Includes Heavy steel mounting brackets E-brake cables rubber brake hoses with matching banjo bolts Frame tabs and clips for hoses Grade 8 hardware and nylock nuts (everything you need) Charts (PDF) (PDF) Installation Tips For passenger car axles only, 15” and larger wheels only Fits 9 inch housing axle offsets of 2-3/8” to 2-1/2” (measured from outside of housing flange to outside of axle flange, not measured out to axle register but only surface where the rotor sits against). Requires “big bearing” housing ends (for a 3.150” O.D. bearing) with 3/8” bearing retainer bolt holes. 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). This kit is an aftermarket solution. It is not intended to be a direct installation or OEM replacement. Due to changes in production in certain years, your application may require modifications beyond these instructions for this kit to install properly.

Yes, I recommend this product. Disc brake kit & axle pads Rated by Fun Car on September 04, 2021 Summary: Purchased kit with the purchase of a complete 9" differential assembly. Ill either narrow the axle pads or make a new set - no big deal! Cons: Axle pads 2-1/2", need 2" - my error! Calipers should be coated to prevent corrosion No T-Bolts supplied Pros: Axle pads very well constructed Very comprehensive brake set Yes, I recommend this product. As advertised Rated by Joey on June 24, 2021 Summary: As advertised Yes, I recommend this product. I might buy it again Rated by None on June 14, 2021 Summary: Basic kit is nicely matched, but needs t-bolts added, stock ones arent 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. Cons: Lug holes precision is very poor Nearly all axle flanges will need trimming New correct length T-bolts arent provided Rotor lug holes arent sized properly, Rotors are cut, not ground Pros: Nearly complete kit Yes, I recommend this product. Made them work Rated by Jdm on March 05, 2021 Summary: Rotor bore did not fit axle flange, was able to enlarge and complete the installation Yes, I recommend this product.
