Question Unbalanced rear pad wear occurred

Just putting this out there for others. While on a scenic Sunday drive the drivers side brakes hit the metal plates. Odd that it seemed I changed them not that long ago. Anyway, I got a new set of pads for the rear. I pulled the affected side first and discovered (not surprisingly) the piston side was scored too much to really use any longer. I got another rotor for it and got it all back together. The passenger side pads were approx. 25% worn in my guestimation hence not doing too much. I pulled the caliper up and out and was able to get the piston to come out with peddle pressure, so it not seized and went back together ok. Testing further with the wheel on and engine running after a short round the block drive with the wheel jacked. Applying brakes a little at a time got the wheel to lock up for my arms to turn it. It seem to be ok and working.

I have no idea why the braking was unbalanced unless the ABS brake controller is unbalance applying forces to the calipers. I'll watch it over the weeks and see if anything looks odd.

I don't know if anyone else is having this problem and this is the 3rd set of pads that were on it when it happened.

I talked to a local mechanic and he's seen this on a number of Chrysler vehicles. Caliper defective as they aren't releasing after being pressed during braking. Another very poor quality part on Jeeps. This sucks that means the others may also need replacing soon enough. I can't bleed by myself so he's going to do the work. It won't take long to do anyway.

Repairs are now done:
- new caliper
- bleeding both rear calipers (just in case)

So if you have this problem you'll need a new caliper on the offending side. This is a problem with many Chrysler vehicles according to the mechanic. He was doing a Caravan as well after me with the same issue. NOTE: This is not covered by the Power Train or likely standard warranty. I had noisy pads in the rear after 20k brakes are excluded from base warranty so you're likely on the hook from the get go if the calipers give up the ghost. Also may other and even much older vehicles have their original calipers (steel) still working as I do in my 2002 GC which 289k on it. Ford 2002 Explorer also original calipers. The quality of parts have really become really bad in newer Chrysler products which is likely why they're bottom dweller in JDPower ratings.
