Robert Wylie Disk Brakes for your Henry J     Here are the Pictures and what it takes to put disk brakes on your Henry J. Using every thing from the stock Henry J. You take the backing plate off and the brake drum off the hub. Too remove the brake drum off the hub grind the heads off the rivets and knock them out with a punch. If they are hard to get out you can drill a 3/16 in. hole in the center of rivet will make easer to knock out. You have to take a little off the outside of the hub for the rotors too fit over the hubs. You have too put studs in the hub or use 1 1/2 In. bolts and run the threads all the way down to the head of the bolt. Put bolts in from back of hub and counter sink the back of hub for the bolt head too go down to hub do’s not have to be very deep. Use lock tite on the bolt to lock it in. You can take the hubs to a machine shop and have them put in studs that are pressed in from the back. You cut the caliper Brackets from 1/4 or 3/8 steel. I used 1/4 steel and used more shims. They work just as well. It will take 4 of which one you are going to us. Stack and tack weld together too drill the holes and tap the top ones for the caliper too bolt on. Make sure you start the tap straight, I did all at one time.   The brackets will have to be shimmed for the caliper to fit over the rotor right it will take a little over 1/8 in. shim for 3/8 in. brackets and little over 1/4 in. for the 1/4 in. bracket. Bolt the brackets to the spindle but don’t tighten till you put the caliper on and tighten it.  Then tighten the other bolts. Then you take the caliper off to put the rotor on. You might have too held the caliper on the back of rotor to bleed out the air. I had to on the driver’s side only. You use the pattern for the clearance you need. One side is for a real close Caliper- Rim clearance and you will have to grind a flat side on the caliper bolts so they will clear the rotor and grand the top of the caliper down. One side is higher than the other so grind the high side down to the low side. The other is for if you don’t need too be concerned about Caliper – Rim clearance. The stock rims will not work.  I used the stock master Cylinder and did not us a proportioning valve. The brakes work great.
