Power washing

[hyah hytes]

Good day, I recently power washed under carriage Dodge ram 1500 Big Horn, then the next day I replaced one of the pressure Valve on the front tire with a regular valve. I'm awaiting a new pressure valve, then the guy put 40 psi in all the tires /22 inch rim. As I left the shop the abs light came on along with the trailer brake notification..on the dash it basically read all the brakes need serviced also hearing a noise from the rear. What could be the cause?. Thank you

tires should be at 36psi. as far as the brakes, most likely water is the culprit, especially using a power washer...that force could have entered into connections. i'd give it a few days to dry out.
the noise is anyone's guess.
