Vaccum Assisted brakes

[65Cabby]

I have a question on the vacuum pressure required for a servo assisted brake system.
I'm fitting a 944 master cylinder and booster but am pondering the method how to get the vacuum to it.

Should I tap each of my inlet manifolds to even out the pulsing cycle? , will I need a one way valve? Or do I go for an electric pump??

Just out of interest as I've never looked at a scooby engine that would originally have a vacuum system, are they always single induction bodies with one vacuum pipe or do some have twin setups.

Thanks

I'd think a one-way check valve and used vacuum reservoir from a wreck would work.

I remember the good old days when it took a real man to drive a car. You had a big ol' 6000lb piece of Detroit's finest. The big block engine weighed heavily on the manual worm-and roller steering system, the straight master cylinder hooked up to four wheel drums. The clutch linked via a rusty cable to heavy clutch. Yes, the good ol' days when driving was a 'sport'. Physical fitness was a requirement, and your daily workout was the drive. These days we have these power-everything featherweights that can lock the brakes with the merely a touch of the pedal, that you can operate the clutch with your pinky toe and that can be steered with your one finger.

Kidding aside, what brakes are you running that justify a booster?

I've taken on a project that already had the 944 master cylinder fitted so I'm not sure I can justify it myself. From what I've been reading fitting brembo's doesn't even need a larger master cylinder let alone a vacuum booster / servo. Although the feel as you say is going to be nice and soft (for when the misses drives the car)

I have vented disks and 968 callipers all round.

After DORIGTT's post I've been looking at vacuum reservoirs but they only seam to sell in the US, I've not heard of them being fitted to european cars other than big 4x4's

Pardon my french but all you need is a Big *** master cylinder. Wilwood makes a 5/8'',3/4'',7/8'', and 1'' master that'll push my 6 pots at all corners with out having the "detroit muscle real man brakes'' feel. If I wanted that I would've put dump truck drums at all corners... I thought my brakes were big until I saw drums so large the rims must be 22.5''s. Commercial only and I think you would need 2000 hp to spin them let alone fit the damn things.

Save yourself the headache and talk to Lanner@vdubcustoms.com. He does this for a living, he knows what he is talking about.

Nice brakes by the way.
