no power brakes at high rpms
so the other day I noticed I had no power brakes after racing past this moron on the road the other day after passing him I needed to make the next turn hit the brakes and had no power assist until rpms dropped to 4500 or less. I then decided to smoke test the brake booster and it and it was leaking so I replaced it with another one, used but it was working good on the truck it came off. still I have a rock hard pedal at high rpms. trying to figure out if im supposed to be using the 3.4 booster or not.
