Hey guys I really need some help here. I just recently had my brake pedal valve replaced. Afterwards my brake lights came on and wont turn off. I noticed that when my trailer brake air pressure is above 120 psi my brake lights on both tractor and trailer come on and will not turn off til it is below 120 psi. I tried replacing the stop light switch but did not change anything. I am not sure if it is related to the valve being replaced or not. Any suggestions on something to check please let me know.
