Read these instructions completely before installing this kit!!!

Make sure this kit fits your application before painting or plating. Parts that have been painted, plated or modified may not be returned.

This Conversion Kit uses the following components:

Calipers

  • 70-77 camaro

Bearings & seals

  • A-6 inner bearings
  • A-2 outer bearings
  • 7934S grease seals

1.   Remove the drum brake assembly so all that remains is the spindle. Inspect the spindles for grooves and cracks. A piece of 180
grit emery cloth can be used to clean the spindle. Be sure to clean the 5/8” threaded hole at the top of the spindle. Use a threaded tap if necessary.

2.   Take the small support bracket and install it to the face of the spindle using the two lower holes, as shown in the attached diagram. Do not tighten yet.   Install one of the supplied 7/16”-20 x 2 3/4” bolts through the rear hole of the bracket, spindle and steering arm. Install the supplied 7/16”-20 x 2 1/4”  through the front hole of the bracket. Tighten down with supplied lock nuts.

3.   note: due to casting imperfections, it may be necessary to grind the steering arm on top rear to clear bracket.

4.   Take the caliper bracket and attach it to the spindle as shown in the diagram. Insert the supplied 1/2” x 2 1/2” bolt through the bracket, supplied spacer   and support bracket. Using the 1/2” lock nut, snug up the bolt. Do not tighten yet. Insert the supplied 5/8” x 1 1/4” or 5/8” x 1” bolt through   the bracket and into the spindle. Tighten down both the 1/2” and 5/8” bolts.

5.   Pack the bearings in high quality bearing grease and install them into the rotor. Also install the grease seal. Install the rotor on the spindle with bearings.  Use the spindle washer and nut to keep it all together.

Warning!!

Stock drum brake wheels may not work with disc brake conversions. Drum brake wheels were not made with disc brakes in mind so there may be wheel to caliper clearance problems. Before installing this kit, make sure your wheels fit the brake assembly.

For those wanting to keep stock wheels that interfere with the installation, there are companies such as Wheelsmith, Stockton Wheel Co. and Wheel Vintiques that can remove the original wheel centers wheel centers and re-install them into a new disc brake rim. Please call for more information.
