I bashed my head against the wall until I went to my local auto parts store and rented their tool set. Best idea evar.

That is a retraction kit for a caliper which has an integrated parking brake function. The way the parking brake works is by rotating the caliper, so it's not possible to just push on it with a C-Clamp.

That tool allows you to push on the piston, and rotate the piston at the same time, so it will retract to clear new brake pads.

That's part of the reason drum brakes never quite went away. The mechanism for a disc parking brake are complicated and expensive to engineer.

Gotcha. Figured your car must be different than most to require anything more than a C clamp.

Most Hondas use a similar system of integrating the parking brake into the caliper as opposed to a separate cable actuated drum brake.

So it's not just VW.

my mini had these too. I got pretty good at pressing/turning w/ a big pair of needle nose pliers, but the specialty tool is a LOT easier.

I use a set of long nose pliers, stick them in the grooves then rotate 'em.
