S4 rear calipers

["Frank Amoroso" <famoroso@sprintmail.com>]

Well all I pulled the rear calipers completely apart. It was a little tricky
but shouldn't be a problem going forward (not that I will ever need to take
them apart again).

Does anyone know where I can get the seal for where the parking brake enters
the caliper? It is one of those black rubber jobbies that is very stiff on
the O.D. while the inner portion is soft rubber and has a circular spring
keeping tension on the shaft.

The following is stamped on the seal: IEL 16 x 24 x 6 x 6.5.

In addition, any suggestions as to what kind of grease to use when
re-assembling the parking brake side of the caliper?

Thanks,
Frank--
