Brakes

[Jeepwm69]

Well my brakes need work.

I'm pretty sure I have a sticking caliper at a minimum. Figure with the truck being 37 years old, I probably ought to replace the rubber lines, do a full system flush, and either replace or at least clean up the calipers.

If I DO need to buy a new caliper, are reman ok or should I buy new? I know some reman parts just don't last (steering gears, AC compressors).

I can get a lot of different reman calipers, but looks like Raybestos is the only new option.

When I crack the system open, is there a proportioning valve that I'm going to have to "reset" so to speak when pressure is lost?

I'm a Jeep CJ guy. The prop valves on those have a little button you have to hold out to allow fluid to go to the back. Guess it's a safety feature of some sort. Does these GM trucks have a similar setup, and if so, where's the prop valve located (I'm at work, truck is at home, and I'm trying to work up a game plan/parts order)
