My brake lights do not work with the foot peddle. They work fine with the trolley brake lever. The brakes work fine. I have changed the brake light switch. It appears as though I am not getting any air to the switch. How does the double check valve work. I am either not getting air pressure through this valve or I am not getting air pressure from the air pack. Any ideas on how to test this.
