I have a 1986 Audi 4000cs Quattro and lately the rear emergency driver
side brake keeps locking up. Its getting so hot I can feel it
radiation off the rim. Its just that one brake too, I'm not sure even
where to start on where to look for answers on what it could be. We
have been told that a few Audis have the same problem with the
emergency brake locking up but I'm not ready for it to worp itself
cause its so hot when Im driving around. Anyone have any advice or
knows if its just a part I can replace or something.

I would guess that the calipers are the same as the T44 series that I
have experience with. If so, you will findthe E brake cable runs to a
rotating clamp looking part. This rotates a small amount and often
seizes. Most people replace it but it can be loosened up be using a big
wrench and some penetrating lube. Once loose apply more water resistant
grease.

As Tony says, you can try to free up the stuck part, but the fix is no
very lasting.

The proper fix is to replace the caliper. Do both sides while you're
at it.
