Getting ready to hit the road and I decided to check the brakes on our 2021 5.0 TA to see if they were working. With one side, the the other, I used the manual brake slider on our 2018 F150. I got three of four wheels to lock immediately but nothing on the fourth.
I pulled the wheel and inspected, everything looked good. Then I tested the wiring at the drum with a 12v light tester. Nothing on either wire, so I know I'm not getting power at the hub but I couldn't see any sign of damage to the wiring. It's entirely possible that I've never had braking at the right rear.
Any suggestions for next steps?
