Installed the disc brakes today and here are some things I did which others might find valuable.
First thing I did was spray the brake line and retainer clips on each wheel. Then loosened the lugs and center spline nut, then jacked it up and removed the wheels and the center spline nut. 15 minutes after applying WD-40 I unscrewed the LF wheel/side brake line and removed the retainer clip.
Now I used a deep socket to remove the 4 bolts holding the wheel bearing and subsequently the brake drum and pulled it off. I then reamed the brake line bracket hole every so slightly because the new part is a tiny bit bigger.
After putting all the new parts on, I then bled the brake line with a small hose. Bending it closed on the brake pedal upstroke, unbending on the down stroke. I all but emptied the master cylinder, refilled it and then emptied it 2 more times to get fresh fluid in there.
Then I screwed the new brake line into the caliper, fixed it into the holder with the clip, added the adapter to the brake line just finger tight before then inserting the brake line and adapter into the new flexible brake line side. It’s easier to add the adapter first then try to get the small ridged brake line connector into the adapter after it’s already installed. Now install your wheel or spacer and then bleed the caliper. I used 2 lug nuts and a long 3/4" box end wrench to keep the rotor from spinning while I tightened the spline shaft nut and bolting on the spacer. One end of the box wrench goes on a lug nut, the shank of the wrench rests on a flat surface of the other lug nut. Others use thin strips of wood but this worked great since I had a long 3/4" box end wrench.
A note on the spacer(for stock 12" wheels ). They come with lug nuts on them and those are to be used to attach the spacer to the hub. The lug nuts in the kit/bag are for holding the wheel on. They are different.
Do the same to the other side except you don’t have to empty the master cylinder to clear the fluid. But you do have to watch the fluid level in the master cylinder and top it off. If you empty it then you have to rebleed not only your front brakes but also the rear too. But you should bleed the rear anyways since you’re using new fluid.
The disc brakes work GREAT! One foot stopping and I feel way more comfortable at top speeds, going down hills and/or driving fully loaded.
