Disc Brake Conversion Kit

This Conversion Kit uses the following rotors and calipers:

ROTORS:

  • 69-72 Chevelle (or GM equivalent)

CALIPERS:

  • 70-81 camaro (or gm equivalent) when supplied
  • uses 79-81 Camaro with 10mm.

Bearings and seals:

  • A2 outer bearings
  • A13 inner bearings
  • 8705s bearing seals
  • mounting hardware
  1. Remove the old drum brake assemblies so all that remains are the stock spindles. Inspect the bearing surfaces on the spindle. If the spindle is grooved, a piece of 180-grit emery cloth can be used to clean it up.
  2. Install the bearing adapter onto the spindle. The adapter will need to be heated so it can expand for easier installation. This  can be achieved placing it in boiling water or setting it on a light bulb for about 5 minutes.
  3. Install the caliper mounting bracket on the spindle, with the caliper opening towards the rear of the truck.
  4. Take the inner bearing and slide it onto the spindle. If the bearing will not go on, use a piece of 180-grit emery cloth to take down the spindle.
  5. Remove stock inner race from rotor and replace it with the race supplied in the A13 bearing set. Grease all bearings and install them with the grease seal.
  6. Install the rotor onto the spindle and tighten the spindle nut. Install the cotter pin and dust cap.
  7. Install caliper with the bleeder pointing up. Make sure everything is good and tight and proceed to bleed the system.

    do you have a kit like this one for a 6 lug setup? we want to reuse the stock spindles and bolt a bracket…you are the only ones I have found that will even attempt to do this. Let me know….I have a 69 chevy pickup 1/2 ton long bed…with stock drum brakes…need something better.

      We only offer this type of disc brake setup in the 5 x 4.75″ bolt pattern. We can set you up with a stock height 6-lug disc brake kit, but it would include new disc brake spindles.

    Im looking for a kit like this for a 85 chevy c10, converting the stock 5×5 bolt pattern to a 5×4.75. do you guys carry it?

    • admin says:

      We do carry a 5 x 4.75″ bolt pattern rear kit but it is designed to fit the GM 10 & 12 bolt type rear ends and the truck type has a different mounting flange. Are you running the original rearend?

    I did disc brake conversion in my C10 69 with upper control arms,dust shield, spindles,rotors and from a donor C10 80, I also install new lower ball joints ,new outer tie rods and 73 87 adjusting sleeves. the probem I found is inner tie rod is loose because is thiner than outer I solve the problem cuting old and new sleeves and welding half old and half new sleves. I think of this could be unsafe thats why I want to know if you have custom adjusting sleeves with the 67-69 size at one side and 73-87 size at the other side.
    thank you

    I have a 62 chevy truck frame that has had 21/2 inch drop spindles added. Part of the disc break conversion was done however I am missing the calipers. The rotors are 12 inch 6 lug chev style. The mounting holes for the calipers are 7″ apart. Do you sell the calipers I need to complete this conversion?

    I have a 69 Chevy C10 with a six lug drum pattern. I am interested in converting the front drum brakes to discs. I would prefer not to chang the spindals but at the very least want to keep the stock height. I have been told that the resident fluid presure needed for discs is lower than drums. do I need a new master cylinder or is there another solution and what is best? All advise is apreciated. Thanks

    I have a 1960 Chevy Pickup Apache 10, Looking to upgrade to complete disc brakes and also going to a power steering setup. I am interested in purchasing them all from you and possibly a new steering column too. Currently, brakes are stock and it is a 6 lug setup. My installer said that I may need to do drop spindles to get to the desired ride height. What is the best way to go about this?
