This time not on my G35 but on my Audi A8.
I’m fairly certain I have a seized left rear caliper. The wheel itself was scorching hot when I got home today. Both the inner and outer brake pads on that side were damn near completely worn out (evenly) too.
I cannot get the caliper piston to rotate and retract (per this design). It wont even budge with channel lock pliers.
So, a new caliper is on order as we speak.
