What's in the Box

Info

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.

Not correct for my Elcamino

June 27, 2016
Wanted Ebrake, but mechanism doesn't clear the frame of 1985 Elcamino, placing on bottom of axle not a good plan. Wish I'd known that earlier. I ended up without Ebrake. I would have bought it without the Ebrake.
Pros:
  • Priced Competitvly
  • Top Quality Kit
Cons:
  • Rotor On Bottom Not
  • Better Desiign Needed
  • Ebrake Hits The Frame
Yes, I recommend this product.

This brake kit is for axles with 5 bolt lug patterns and if your pickup has not been altered it would have a 6 lug pattern, therefore the kit will not work. We apologize that currently we do not have a 6 lug brake kit for your application.

Will this fit an 8" ford with 3" between housing flange and buggy spring mount? I have read that some kits will not fit if the buggy spring mount is too close to the flange. Also, is 1.94" the minimum axle offset? It looks like mine is 2.25".

The rotor hat itself has 1.94 offset and is the common one used for housings of 2 1/4" to 2 1/2" axle offset. The steel hat version has a deeper offset of 3” and will have problems with caliper clearance with your buggy spring mount.

This brake kit uses 1.94" backspace brake hats. Take some measurements for clearance on your Nova to be sure it will fit. You should be able to reuse your factory emergency brake cables as long as they can be routed correctly to meet up with the caliper.

This is a universal brake kit. You will need to check to be sure that the OD of the axle as well as the brake register size is compatible with the brake hats in this kit. The hats have 1.94" backspace and will accommodate up to 6.14" OD axle flanges as well as brake registers up to 3.06"
