Learned something today. The port closest to the push rod is for the front brakes, correct?
That being the case, I only have the front brakes hooked up now and the pedal goes to the floor. Any ideas? The brakes are mounted below the cab. Years ago I put a 10# residual on what I thought was the rear brake line but is actually the fronts. It is still on there and there is no change in performance. Pedal still gets real low to floor.
