Looking for some help.
Ive had the truck for a few months now drove it over 6hrs home no issues truck is in great shape everything is funcitional including the CTIS. Last week I started having issues out of my air brakes when you spet on the brake it releases pressure like it should but then continues to bypass air out of the snorkel. Ive changed all 3 check valves under the drivers step, all new pancakes in the service brakes whick all but 1 where the original rockwell pancakes. The truck builds and holds air pressure just fine until you hit the brakes. I know it cant be on the parking brake side either because they function as they should. The air brake foot valve looks like there has been a leak there before but doesnt sound or seem like it is now. Any help please.
