    I recently did my rear brakes (pads and rotors) myself. Everything went well and I triple checked the caliper was rotated to the proper X pattern. Cleaned hardware and cleaned and re grease slide pins.

    Today I wanted to double check that my brakes were done properly so I felt the rotors and one was definitely warmer than the other. I jacked up the rear and both sides spun freely but one side was only able to do 1 full rotation while the other side did 2.

    After my commute home I grabbed my temperature gauge and one side was 90F and the other was 82F. Are these temps normal?

    I have no noticeable change and the car seems to drive good with no dragging noise and I can coast in neutral on flat ground for a good distance.

    Didn’t know if I’m just being way too cautious and over looking into things or if I should pop the calipers back off to double check everything is seated in properly.

    Are you sure you rotated the puck all the way back in? Check the parking brake also.
    Those temp are still pretty low.....
    But you could double check the one side, just to be safe.

    Good point, that’s the only thing I’m not sure if I did. I did rotate multiple times and when it looked flush and the X was correct, I stopped. Are you supposed to wind it until you can’t anymore? Just curious how that would affect the placement of the caliper.

    You likely must go all the way to put in the new Toyota pads. If you used aftermarket, I wouldn't know.
    When I did mine, after going all the way in, I had to rotate them out a little to get the pins to line up, but it
    was only 1/4 of a turn or so.

    I used ADVICS pads and rotors which are OEM for Toyota. Based on your idea I think I will pull off the caliper, retract fully and then pump the brakes to re seat again.

    The parking brake might be sticking slightly on that side. Doesn't hurt to double check.

    Maybe waiting a week or so, keeping an eye on the pad wear for both sides. And see if they
    equal out in temps.

    Take a look at rear brake drag link in my signature. On a phone turn it landscape to see signatures.

    I followed your instructions, even had your list while I did my install! Not sure where I went wrong, will have to go back over everything this weekend.
