S14 Rear Brake Nightmare! halp!

[Too_Short]

Greetings Nicoclub,

My rear pads were pretty weak at locking, so I got some porterfield R4S. Installed them 2 days ago, driver's side caliper seized, not the piston but one of the two little things with rubber boots on them was completely seized. It was so bad that after driving one block trying to break the new pads in my rotor actually snapped off the hub. I drove the car back rebuilt the messed up part with some polish, air, and grease.

The next day I picked up a new rotor for that side, and installed it. Gave it a test and now that pad is rubbing on the rotor, not enough to cause the pad to ever smell, but it does get quite hot. So this is where I've been stuck now, things I know it probably isn't.

-Ebrake cable is in good shape and I highly doubt it's contaminated.
-Ebrake cable is not too tight, I can yank it pretty high still

Clues that might be worth noting.
-The outer edge of the new rotor has some semi deep scratches on it from the pads.
-The metal backing of that side is actually missing, when I pulled the old pads out only the inside pad still had a metal backing on it, I decided not to put it on the new pad. The other side have both metal backings still on.

Right now I'm gonna drive it for a couple days and see how it is. I'm hoping the new pads were just messed up from that rotor being uneven and it'll take a little extra time before the "break in". If anyone has suggestions or help please advise, this is starting to really annoy me. Brakes is supposed to be easy ;(. My buddy has a pair of extra calipers he will sell me so if it gets worse I might give that a go.

Those things with the rubber boots are slide pins. They need to be able to move completely freely. If they froze once, they will do it again. Check out your buddy's calipers and see if the slide pins are in good shape and the boots aren't torn. Even if one of the pins sticks, they pads will drag or bind.

Pick up a bottle of brake caliper lube/grease. Carefully pull the slide pins out of the boots and slather some more lube on the pins and get the boot loaded up too. Do this even if you get new calipers. Sometimes brake pads have a thin metal shim on the back of them, they help dampen noise. New pads should come with all they need, don't put an old shim back on. Also make sure the metal clips that the pads snap into on the caliper bracket aren't all rusted up. They can bind up the pads too. Usually you have to get a new caliper to get these clips, but occasionally they will come with new pads. Put a little of that grease in the contact points between the pads and clips.

Bleed the system real good too,
