Q & A

What's in the Box

If you don't want to spend an arm and a leg on a rear disc brake kit and still have to weld the bracket on, we've got you covered. This kit includes bolt-on caliper brackets, 11-1/4" vented rotors, '78-'88 GM emergency brake calipers, brake pads and hardware.

  • Fits both 5 on 4-1/2" and 5 on 4-3/4" bolt circles
  • For Ford passenger car axles ONLY 
  • Fits axle with maximum flange diameter of 6-1/4" O.D.
  • For 15" and larger wheel applications ONLY

NOTE: This bolt on brake kit is designed to be used on 8" and 9" housings using 3/8" retaining bolts. If you want to use it on a 9" housing with 1/2" bolts, you will need to use the 3/8" hardware to do so. Fits "old" and "new" style big bearing (3.150" bearing O.D.) Ford housings and with axle offsets of a minimum 2-3/8" to 2-1/2".

Application

  • "Old-style" big bearing 9" Ford axle
  • "New-style" big bearing 9" Ford axle
  • 8" Ford axle
  • Axle housings with minimum axle offsets of 2-3/8" to 2-1/2"

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 diamter in the rotor to match the Currie axle spec of 2.795"

Speedway Rear Disc Brake Kit with Emergency Brake, 1.94 Inch Backspace
                        Replace those old drum brakes with modern rear disc brakes. This affordable rear disc brake kit conversion gives you an emergency brake just like your family car has. The steel caliper bracket welds to your 3" axle tube, so it will fit virtually any application. The calipers accept either GM or Lokar type E-brake cables and are tapped to accept the common 7/16"- 20 banjo fittings. The 11-3/4" x .81" vented iron rotors will give you plenty of stopping power. 

Wilwood aluminum rotor hat fits 5 on 4-1/2", 5 on 4-3/4", and 5 on 5" bolt patterns and has a 1.94" backspace.
