New Power Brake Booster - NOT BOOSTING !!! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

. . . .

During my 1970 350's restoration, a new booster / master cylinder was installed and front disc's were added. I can hear the rush of air when the vacuum line is pulled off and the hose is connected to a good source.

The pedal doesn't feel like "power brakes" - the truck stops a little better now, but that's probably because of the added front disc's.

It just doesn't feel like what I remember power brakes in the 70's were like.

Does anyone have anymore ideas of what to check ?
