I'm posting this for my dad's truck, he has a bone stock 03 F-250 with the 7.3 and he likes it that way no matter how much I try to get him to modify it he-he-he. Anyway he called me about his brake pedal fading while stopped at red lights. He was thinking master cylinder and I agreed with him. I drove his truck and felt what he was referring to. We took it to a friends shop along with a new master cylinder, they replaced it but the truck brakes were the same.
Now I've learned that the power steering pump drives the hydro booster and I noticed the power steering level was slightly low so we added some, but it acted the same. I sat in the truck with it running, in drive, foot on the brakes and sawed the wheel back and forth and it took about 5 passes and the pedal was to the floor. My question is which direction should we look next, the booster or the power steering pump? I hate to just take a swing at it, any ideas?
