Your opinion on rear brake working correctly:

[Bailey28]

2013 Dodge charger R/T. New pads and rotors, do you think this rear brake is pulling it's weight? The other side looks identical. I have been driving the car for over a month and I still see heavy crosshatch.

I would say they are okay due to the slight rust on the outer rim and none on the rotor face, the rear brakes usually do not have the same braking force as the front so it may take some time for the rears to loose the crosshatch completely.

My guess is it's working because it's scored a little and no rust like Trav said.

 

[Rand]

is it working perfect who knows.. but its doing something to have no rust on the swept area where the brake pads contact.

Did you bed the brakes in as required after any brake job? Do that if you haven't. If not then it will take longer for the pads to seat and transfer the layer of brake pad material to the rotors and wear evenly and the overall brake job won't be as good.

Go for a spirited drive then use an IR gun to get rotor temperatures. The rears will be less than the fronts, but you want probably +/- 20'F side-to-side.

Nothing wrong there !
I did four rotors and pads on my daughter's MKX her rears looked the same as your's I also thought there was an issue so I took it out and did four or five quick stops got out and touched the rotors front too hot to touch back were hot.

Further info, the car stops very well. This is the same car in other threads where I have had the front caliper piston issue. Summed up, the phenolic pistons swelled and were seized on the front calipers requiring they be replaced as the front brakes were dragging terribly. I did all four corners at one time but only the front two calipers have been replaced. The rears gave me no dragging issues upon reassembly the first time.

The rear calipers use the same phenolic pistons. They were easy to push back into their bores just like the fronts were before they seized which lead me to believe these may be stuck as well however they do not drag at all like the fronts did on the first attempt.

The bedding procedure happened very quickly with the fronts, there was no crosshatch left on the fronts after a few days. The rears were along for that ride too but didn't see the heavy usage the fronts did by happenstance of stuck pistons.

I had no idea these phenolic pistons warp/seize/jam etc in the caliper with age. I have done more than a handful of brake jobs over 40 years and never had this issue with any car or motorcycle.
