Other day I heard metal grinding sound comming off rear of driver side
Saw WORN off DISC and Used Pad.
I have replace the Disc and pad on both rears.
I notice driver side rear calipar was jammed and slidind rod was rusted Orange
I had to hammer out to undo the sliding bracket so I can re grease it.
However I notice some thing odd.
Driver side rear where bracket was worn out.
Passenger side had half of its life there. I have added following Pics

Sounds like a stuck guide pin. You should replace it (if possible) or replace the whole caliper.

Keep an eye on it. It will do the same thing to the new pads, if not corrected.
