THANK YOU-THANK YOU-THANK YOU!!,  To all who responded about "beating to death the brake accumulator......." After all your input, and ideas, and after talking to Scott at SJM AutoTechnik , (web address is www.sjmautotechnik.com), it was discovered that the previous mechanic (who shall remain nameless-FRANK), had not installed a small little piston behind the "X" cap on the brake side of my hydraulic pump.  And of course, the nameless mechanic (FRANK!), had no idea where this part was.  But, he would be more than happy to put it back into the shop and work on it some more.  (I don't think so!)  After finding this out, Scott went above and beyond, and rather than selling me the new pump at over $350, instead just sent me the piston, and O-ring kit, for a measly $28.  What a guy!  I now have working power brakes, and it is running great.
Now, does anyone know why the rearend shudders going around corners at low speed?   I don't notice it as much at high speeds, but rather just at low speeds, and it seems worse turning to the right, rather than the left.  Or is this just common of quattros?
Thanks again to everyone!
Kevin
