New power booster but still hard to stop - Page 2

John, if the pedal was hard to push, when you force the old out it usually gets easier, I'm assuming that you had the engine off for bleeding. If so consider rebleeding the system so you have fresh fluid all the way around. Try slipping a piece of clear plastic hose over the bleeder and into a container so you know its clear

Good idea Leo, thanks, I will do that.

I bled the brakes clear but that didn't help. My brakes are kind of here one moment and not here the next. When I tested it on the road they seemed to work ok. I had to apply some pressure at first and then the booster took over. Then out of the blue the next stop was like hardly any brakes. From then on it was a hard pedal with not much help from the booster. I am taking it into the shop and see what they can do.

Dang...my mechanics said the new power booster I bought and installed was bad. The truck is all fixed now. Yahoo!

Congratulations, John. It did sound like a vacuum problem. (Of course I can say that now that the answer is known. :P )
