[urq] My UrQ Brake upgrade

[AUDIJIM at aol.com]

I have installed the following:

G60 front calipers from an S4/S6 = check
276X25mm front rotors from a 5000 = check
Rear calipers form S4/S6/V8 = check
Rear rotors from S4/S6/S8 = check
UrQ new proportioning valve = check
Upgraded master cylinder from 5000 TQ Avant = NO GOOD!!

The above master cylinder did not fit into my brake booster. I have taken 
pictures of the (new) original UrQ master cyl. and the new 5000 TQA master cyl. 
The "upgrade" 5000 TQA MC will not fit into the brake booster all the way.

So I installed my new original equipment master cylinder, pressure bleed the 
system and started the car while it was up in the air. I ran it through the 
gears and the pedal feel is really good. I haven't test drove yet on the road, 
my used rear calipers are dragging and I think the e-brake is stuck on them. I 
have another set of rear calipers to try tomorrow.
