[urq] bomb test variation with S4 brakes?

[brady zq]

Hi Martin/Steve/James/All,

I have the stock urq master cylinder, and the bomb has the same spec as a 
1983 BMW 733i. I don't think it says so on the one I just bought, but  in 
the archives someone mentions 100bar/0.48litre specs for this replacement 
bomb.

Are these the same specs, or close to the same, as the urq's?

My car brakes well now, so I'm not too worried, but am curious. I'll check 
to see how much ATF the bomb really holds soon, and will let the list know. 
It will probably be in the form of x cm drop in the reservoir from empty.

Oh, BTW, yesterday, driving home from a wedding with the GF, on a big 
freeway approaching a bridge, my gas pedal went to the floor. ^$#% foam 
pedal bushing thingies. It was a slow climb over the bridge. Thankfully 
traffic was moving slowly anyways.....

Cheers,
Brady
