Vacuum booster VS 6/8 pots caliper

[popdemonic]

Mates,I finally got the brand new Vacuum Booster from A6 C4 2.8L.
the Vacuum booster size is 10"/254mm.After I have STFA,due to I'm
looking to get the 6/8pots Caliper on my UrS6 in the future.So I'm just
curious in case of putting the A6 Vacuum Booster on the Car.Will the
Vacuum sufficiency for the 6/8 pots Calipers.I have seen some old Merc
W124 which upgraded to the multi-pots brake caliper and finally,he needed
to upgrade the bigger vacuum booster from W140 too.anyone BTDT on these please kindly sharing me some input.

POP.

maybe just an extra vacuum reservoir if your really bothered by things? I've got vacuum assisted brakes (no porsche calipers yet but soon enough) and a aby S2 engine. I've got a few check valves and the stock vacuum reservoir but may add another if i'm really bothered by anything.

Thx for your input Josh.Where did you get the check valve from?Can I use generic check valve from VAG-cars?
Can the check valve handle the high boost?I'm currently running GT2871R with 1.5-1.7 Bar of boost.For the safe side
I'm think to put 2 check valves on the vacuum line?Is it worth for that things?the experiment will begin on tomorrow.
If you have some photos of your setup .I'd appreciate that Josh.

Anyway,how the brake pedal feel after had the Vacuum booster in?better than the stock hydraulic one?
the stock one feels like sponge when apply on the brake.

Is there a guide to doing this on an S2? Can use use parts from an earlier CQ?

if its the same as an s2 then my standards were spongy. with the 6 pots its nice and firm. really nice

If the S2 has Brake Servo,Accumulator and building the hydraulic pressure by PS pump
then we're in the same boat . Anyway,the vacuum Brake Booster(From c4 A6) has 2 manufacturers.one from Girling will be using 10mm Clevis,TRW(Lucas) will be 12mm
Clevis.Boths are shown the same part# 893721213(IIRC). the UrS6 Brake Servo uses
10mm Clevis.So If you've got the Lucas Brake Booster.it means you can't use the Clevis from the stock Brake Servo.FYI.
