2017 F150 rear drivers side rotor is hotter than other 3?
What is your question?
2017 F150 4X4 SUPERCREW 2.7L ECOBOOST 6-SPD with 85k miles. I would at least think that both rear rotors would be close in temp after the same drive. But drivers rear is 110 - 190 degrees and passengers rear and both front rotors are below 80 degrees after a 45 minute in town drive. I brought it into the shop and was told all calipers are moving fine. They test drove it for 5 minutes and said rear drivers rotor is slightly hotter but nothing to worry about. Any idea why one rotor is twice as hot as the other 3 rotors? Any help would be appreciated. Thanks!
What makes this problem better or worse?
Rear drivers side rotor is always hotter than other 3 rotors by almost double.

You're absolutely right—after a normal drive, rotors (especially when comparing the same axle) should be fairly close in temperature. If that rear driver’s side rotor is consistently running hotter, even though the caliper “seems” to move freely, it could still be dragging slightly due to a sticky caliper piston or a binding slide pin. Another possibility is a restricted brake hose that’s not allowing pressure to release fully after braking. These issues can be subtle and may not show up during a short test drive. Since you’re seeing a consistent temp difference, I’d recommend having that caliper and hose inspected more closely or even replaced if the issue persists.
