Not on the 993 (sorry, but it just doesn't need anything). New rotors and pads for the Jag XK.

I recognize those calipers as Continental Teves (ATE). The spring with the yellow paint on it is used to maintain orientation of the fist relative to the anchor.

There are probably two practical reasons for the yellow paint. One, to visually confirm that the spring is in the box of parts at inspection. Or two, to verify it's installed on the caliber.

^^ What he said.

Other than that, who knows? It's British.
