I need to rebuild the front disk brake calipers on my 72' 3/4 and was wondering how to do this? Thank you. Dave

most suto parts stores sell the rebuild kits and autozone sells the tools

Go buy a rebuild kit. Pull the piston out the front, clean everything up, put on a new o-ring, install the piston, install the dust seal, reinstall caliper, bleed, drive away. That is the most basic instruction. You may need to hone your cylinder as well. IMO go buy a brand new one, not rebuilt, they seem to last way longer than a rebuild.

What's involved and what do I have to do to rebiuld the calipers?

rebuild or cleanup? Rebuiding is really simple. Take the calipers off, remove the brake line, plug the hose, remove the pads, pull the piston, check for rust, dirt, and moisture, remove the O-ring and replace. Put it all back together. Put in fresh brake fluid at the resevoir. Have someone pump the brakes and hold the pedal on the 3rd pump. Open the bleeder screw, tighten back up. Do this until a solid stream of fluid comes out of the bleeder screw. Don't forget to check the resevoir ever now and then. You don't want to empty it out.
