Upgraded brakes in a 83 Ur-Quattro

["Paul E. Rivera" <rivera@deltanet.com>]

As a complete neophyte to the inner workings of a Ur-Q, I have been told
how expensive the Hydraulic system is to maintain.
OK, what makes this system so special?
Can it be upgraded to new brakes, bomb, pump, etc?
In what year were changes made to the brake system to harmonize with
other models (200's, V8's, 90 Series Coupes, etc) ?
Are there any Web sites  with juicy techno tidbits about Ur-Q's?

Humbly yours,
