Rear Brakes Locking up first

[johncworden at verizon.net (John C. Worden)]

I have had over 10 A1s, from Rabbits to Sciroccos (MkI, II and II 16V) and
have never seen this in a single one, or in any of the manuals.  Now on the
A2s, yes(and it's pretty cool to able to have some adjustability too).
You may want to take a peek at your Scirocco-you'll see just the regular
prop valve(or valves depending on the year) right near the MC.
