I got the rear stuff put together. The new pads had some kind of spring clip or something with them, not sure what it was for; at least the old setup didn't have anything like it. The 82/83 caliper seems to fit fine, I don't see any differences in it from the one that was on there.

I went to bleed brakes and couldn't get anything out of the rears, pedal just stayed hard and wouldn't come down when I cracked the bleeders open. So it looks like I've got something going on with the master cylinder. When I pump the brakes, I can see fluid draw down through the port in the front reservoir and then the fluid comes back up through the port into the rear reservoir.

Before condemning the m/cyl, I suggest cracking the brake line loose from yer "new" caliper and checking for fluid at the line. I would tend to think the prob is more likely a "non drilled" bleeder-screw hole than a m/cyl, BUT.......I wuz wrong once b4!  <shrug>

The bleeders are drilled on the sides, but it's a reasonable question.

I pulled the master cylinder and proportioning valve. I took the ends of the prop valve and there was some stuff hardened up in it, didn't pull the plunger out of the master cylinder. I hit one of the prop valve caps with some scotchbrite pads and whatever it is hardened up on it just tore up the pad, so I I'm going to go ahead and replace both.

Edit***
I've searched online and can't find a prop valve, I did find a rebuild kit which will hopefully do the job. I'll have to see if I can get all the pieces fully disassembled. They recommended soaking it in ammonia for several hours to assist with cleaning. Sounds like another project for next weekend.
