I’m pulling a 5th wheel trailer when I lost braking power on my foot pedal . I was able to use the manual trailer brake to get my vehicle stopped . When I applied the foot pedal , it became soft with no braking power . There was no indication of any problems on my information screen . I continued on my trip going slow and using my trailer brakes to slow down . After about 30 minutes , my normal braking returned . Anyone else have this issue ?
