Although not required, my SoCal buddy decided he wanted to make
a little modification to the caliper bracket. He drilled and tapped a 10x24 in
the bracket. (note the hole just off the end of my finger)
You can see the 10x24 screw in this photo. The end
result? Well, when I take out those two bolts that previously held the
dust shield and caliper bracket together, the two parts will still be screwed
together. It makes it a little bit easier to handle it as an
"assembly" when everything stays together easily. Once we start
putting the brake shoes and springs on, keeping everything together just makes
it easier, especially when you are trying to get everything attached while the
axle shaft is being put back into the tube. Note that you do NOT need to do this little
modification, but I sure am glad we did.
Earlier, I mentioned that we needed some 3/8" grade 8
bolts. These will be used to secure the retrainer plate and bracket to
the end of the axle flange. The factory uses pressed in studs, but these
will now be too short and so you will need to remove them. A 1 1/4" bolt will do the job nicely. In
order for it to properly fit at the axle flange, a flat spot on the bolt head
was needed. Not too hard when you have the right tool handy.
After a few seconds, the bolt has a nice flat spot ground on
it. Do the same to the remaining seven bolts. You'll use four of
these bolts on each axle flange, replacing the factory pressed in studs.
Next, you will need to remove the factory drum
brakes. In the picture above, a socket is used to reach the four nuts that
hold the factory retainer plate in place. As was suggested to
me...."just get the
brake shoes and springs and such off". Since they are not going back on, no
biggie in what order you take the stuff apart, as long as you get it all
off. None of it will be used for the conversion.
Once you have removed the axle shaft and the brake
components, you are left with the four studs in the axle flange.
With a brass hammer in hand, a few light taps were all that was
needed to pop the studs out of the axle flange.
Take four of the 3/8" grade 8 bolts that you ground a flat
spot on slip them into the axle flange. When you do, you will see why you
needed to grind a flat spot on the bolt head.
