Has anyone had any issues with their built in brake controllers on the 05+ trucks? Mine barely works and almost put me through an intersection the other day even at the max level 10. If i squeeze the button it will grab the brakes but will not completely lock them up. The trailers are new and not the problem since they work fine with the digital controllers in my other trucks. Suggestions?

 

I saw a post here this week that said pre- (some build date in 05)(update: March 23rd, 2005) the voltage to the brakes was <5, and after it was 10-12..

sounds like this might be affecting you..
