You could eliminate the brakes as a cause of the shudder.....When that
shudder is happening, pull over and walk around the car, putting the palm
of your hand on each wheel.....feel the temperature the wheel. If the
shudder is associated with brakes grabbing, you won't be able to keep your
hand on the affected wheels very long. Eventually there was smoke and the
smell of hot brakes when this condition was at its worst......but it crept
up on me.
That is how I became aware of a brake grabbing problem on my 87 5ktq a few
years ago....and it required replacing the master cylinder.
Here are some other symptoms, as seen by another quattro list member (Ron
Wainwright) back in 2002: "I was coming to a stop sign up a little hill and
when I stopped I put the car in neutral, but I didn't roll back. Car kinda
felt like it had the E-brake on so when I got home I checked it and noticed
that the rim and rotor were very hot to the touch, so the next day I took
the caliper apart thinking that the piston was frozen but it wasn't ( and
my E-brake cables have been disconnected prior) and bled the system didn't
notice any thing after that for a week then while pulling in the driveway
at night I noticed the rear driver side rotor was glowing red but I know
that the calipers are working."
