[QUOTE="JrStroker, post: 972908, member: 10822"] Truck is an 08 Job 2 F250 Spartan, full exhaust, intake, egr delete, studs, 6 inch lift on 37s So a couple weeks ago I was driving home and my power brakes and power steering went out. The pedal would engage brakes but wouldn't return to normal position after I let off. I had to pull it up with my foot. On the way home my power steering pump started making a awful noise. So far I replaced the power steering pump and put it together. Still no power brakes or power steering. Got a P0703 code, input circuit B, and did a little searching and figured out it was the front most sensor in the master cylinder was bad. So I replaced that, and the power steering is back and so is the power brakes, but the brake pedal still won't come back on its own. So now, the pedal is really hard when first pushed on then goes soft and goes to the floor. The brakes stay on and truck won't move until I pull the pedal up with my foot. Also can hear a bit of a hissing noise under the dash, like fluid flowing threw a restricted hose. Still getting the P0703 code and also getting a trailer brake module fault on the dash screen. Anyone have any info that could possibly help me? Thanks guys. Cory Anderson [/QUOTE]
