Master Cylinder - 200Q20VTQ made of unobtanium?

[Big Brake Parts]

Ben,

On one 89 Jetta there was the same problem. Fronts binding when heated.
Replaced calipers and cylinder. No changes. Finally added 2mm washers
between master cylinder and vacuum brake booster (with thicker rubber
o-ring to keep the seal). No more binding.

Bernie,

Not sure what you are driving at.  I have a well maintained system relatively speaking.
It has been bled/flushed every few years - more than most cars I've seen.  This will be
the second set of pads I've replaced.  Don't know about the prior owners maintenance on
it, but he was former Audifans/Quattro listmiester.

I don't know why these MCs have a habit of binding when heated.  I just flushed the
fluid - helped, but still starts dragging front caliper when things get hot.  I've seen
this on almost every 5000/200 I've owned.

I might be into rebuilding the caliper at over $400, but at $125 not worth my time.

Ben

Apparently, because there is no demand, and rightly so. And you’ve replaced these in the
past, why?

IMO, in a properly maintained system they should be good for the life of the car, along
with the other components of the system. Further, if abused they can be overhauled.
