OK, I'd been leaking a little fluid from my 88's front brake caliper, so at 185K miles and 24 years, figured it was time to do something about it. I bought both a lifetime rebuilt caliper and a Brakeware #66403 made-in-USA brake caliper repair kit, figuring to return what I didn't need.
I took off the caliper and found (luckily) no brake fluid on the pads, so don't have to replace those. I could see some seepage of brake fluid past the dust poot around the piston.
The piston came out pretty readily (maybe because the seal was bad), didn't have to use compressed air to force it out (good, because I don't have acompressor, only a 120 volt tire inflator. The piston and the bore looked pretty decent.
There was a little rust in the groove where the dust boot sits. The actual rubber seal goes in the groove farther inside. This photo was before I cleaned it up.
The #66403 kit is pretty bare bones, comes with a seal, a dust boot, and the spring-retainer for the dust boot, cost $9 (the rebuilt caliper is $36). I decided to try the repair kit, since it was made-in-USA. The kit installed readily, I lubed everything with clean brake fluid. Note to self: next time, add brake fluid through the banjo fitting hole before bolting the caliper back on. I got Mrs. Cusser to demonstrate her brake bleeding skills, and buttoned it up. I'll keep the intact caliper around for a month or so until I establish that my repair is leak free and operating properly.

Nice write up, I will probably do mine some day but luckily they are still dry as the Sahara forest.

Thanks, Earl taught me to do write ups !!!
Funny: as "unreliable" as the brake master, clutch master and slave cylinders have been on my truck, I'm pretty sure this is the first brake hydraulic at one of the wheels that I've had to attend to, in over 17 years with this truck.
Now: was it worth it to rebuild v. installing the lifetime caliper? Time will tell. Today it was about 60F then (Phoenix), and I had plenty of time to do the job. Yes, using the rebuild kit was more labor time, but I wanted the challenge. The rebuilt caliper would've been easy bolt on and bleed, would not even had to have touched my brake pads at all !!! The rebuilt caliper came with sealed bag of copper washers, new bolts, etc.
