After the truck sits for awhile, the power brakes are lost, and it's easy to unintentionally let the truck roll forward or backward while starting if you aren't really standing on the brake pedal. (Remember, this is a 5-speed stick vehicle, so to start you press the clutch -- if the e-brake isn't set or isn't strong enough, the vehicle rolls until the engine starts and provides vacuum). The brake pedal also feels hard, like there's no power boost.
After the truck starts, everything is fine. I've replaced the little check valve on the booster but that didn't do anything.
I assume this means there's a vacuum leak inside the booster, and the booster needs to be replaced?
