Bonaldi Brake booster REPAIR Kit - part number/Link?

Do you have a stock master or one of the conversions to later model Ford or GM masters with an adapter plate? Adapters I have encountered have used different than stock seals.

- it is NOT the Main Cylinder..is brand new..
- issue is the "vaccum booster - bomb" in the front trunk", which has the vacuum line from the engine.
Test 1: With engine running it makes a noise as air goes back in the Vacuum booster.
Test 2: Suckung per TEST device on the holse does NOT build up any vacuum
Test 3: sucking per mouth (!) on the hose from below...NO resistance, i.e no vacuum building up

Looking for rubber gasket set for the   Vacuum booster/Bomb

any thoughts? or do I need a  new one?

ok I am shooting too fast found much more info on the Forum..

...looks like lots of bebuild folks doing it..

I understand that.
There is a difference in the diameter of the pushrod that actuates the master. The stock pushrod is smaller than the ones furnished with the Ford/GM master cylinder adapters and uses a different seal. This particular seal is part of the booster, not the master cylinder.

tx Larry,

I started a conversation with the folks in Modena/IT per Eugenious link. Let me see what they come up with..I have NO idea on the push rod diameter as the vacuuum booster has no more a type stamp. ON the Master cylinder there was the US Bath tub including the ADAPTER 4 to 2 bolds I did replace them!!!
..but as you said this is again independent on the Boster problem itself. 

Question remaining: Is there an issue on the PRECISE length of the push rod as I chnaged to a Europen Master and NO ADAPTER 4 to 2 ? I did check the binding gap  but NOT on the last 1..2 mm ..

Lieber Matthias. I sent my booster to „Casa del Freno“ in Modena. Speak to Fabrizio. I sent him my booster and he returned it completely rebuilt with new a new diaphragm. Liebe Gruesse from Duesseldorf
