1993 mgm rear disc brake pad wear

[Donal]

Recently put new rotors and brake pads on the rear. Also put new pads and one new rotor on the front. Also put a new brake line from the master cylinder to the drivers side rear wheel. I had noticed an occasional noise, of short duration, sounding like something rubbing as the wheel turns, sounding like from the front left wheel. Usually noticed when wheel turned to the right. Also on occasion notice a moaning noise/ feel of short duration. The other night , when returning from an errand, noticed a smell like wire burning or something. It was coming from my left rear wheel, and the wheel was almost too hot to touch. Jacked the car up and took the wheel off. Noticed from the wear on the rotor , that only about half the pad was contacting the rotor. Looked at the passenger side and it looked the same. Looked at the front wheels and the pads looked to be making full contact with the rotor on both sides. Looked at the inside rotor on the left rear and it also is only making contact with about half the brake pad, except the wear is near the center of the rotor and the wear on the outside of the rotor is toward the outside. I have since taken a couple short test rides and all seems fine , with no excess heat or anything. I don't know what to think. What's causing the pads to wear like this? What caused my left rear wheel to get so hot? Do I need to replace my rear calipers and put another set of pads on? Can anyone sort this out?

pads arent seated right, pads look twisted in the caliper.

i would replace both rear calipers since they are prob 22 yrs old

Just took a spin around town, and the left rear wheel smells to be fairly warm. Didn't even bother trying to touch it. Guess I'll follow that suggestion to change both calipers. For sure am not gonna be driving it till something is done. Should the pads be replaced also?
Thanks,
Don.

I would - probably already have issues and you already in there. That way, everything is new at the same time.

What Bobby said! Buy yourself peace of mind, nothing worse than having to do it again because something wasn't done. I started watching RoadKill on YouTube and those guys rebuild junk and get it going. They always do the brakes but what do they always end up going back to replace? Wheel cylinders or calipers or lines because they didn't do it when they had it apart the first time.

Make that "you're already in there"! My mind was on vacation....

Seems nobody keeps parts for this car in stock. Most offer next day. I did manage to get the calipers from an Orly in a nearby town. AZ is gonna allow me to do a warranty swap on my pads, so that was pretty great. They won't be in till the morning. Didn't particularly want to work in all this wind anyway. Looking forward to getting this thing straightened out. Thanks to everybody for all the help.
