5000 tq rear calipers

[Larry C Leung]

You have antilock? I haven't really looked into this too deeply, no need
for a mechanical second proportioning valve on these, unless Audi wanted
to spend more....$$$, oh, uh it's an Audi isn't it? (seriously, if there
are 4 lines running to the proportioning valve, then there is only one
unit. The other proportioning would be the anti-lock system.
