brake question??

for you engineers....what would happen if you increaced your master cylinder diameter( like going from 1" to 1 1/16) would pressure increase, or remain the same and just increace volume???

thanks Jim

You'd need about 13% more force from your leg to get the same pressure in the MC (and at the brakes). On the plus side, you get about 6% more fluid volume for a given movement of the MC rod.

That must be why the boosters are so big.

thanks George....so if I'm understanding this right..if I was to decrease the master cylinder bore size to a smaller size it would increase pressure??? but then I might not have enough volume...

With a smaller diameter and the same foot pressure on the pedal, you'll get higher pressure out of the MC. You'll also get less volume of fluid for a given amount of MC rod movement.

thanks again George, sorry for not posting this in the brake forum, but this seems like a better place for this type of question concerning older trucks
