A6 brake job

[Lee Levitt]

Just a quick question. I'm replacing front brake pads on my '96 A6 quattro
and have just consulted with my good friend Robert Bentley.

Looks like I need to remove the guide pins to remove the caliper, and that
they take a hex key. Can someone tell me what size key to use...I need to go
enhance my toolkit <grin> and would like to know what size to get.

Thanks!
