When I recently did my front rotors and pads I noticed the dust boot had come partially loose from the caliper (does not appear torn or otherwise damaged).

I was not able to figure out how to reinstall dust boot into the caliper.

The brakes are working fine- but if there is a method (short of overhauling the calipers) I would like to "re-open my patient" to fix it properly.

Perhaps I did not look closely enough, bit it appeared to me that one would need to remove the caliper and pop the piston completely out before the dust cover could be correctly installed. I hope that there is an easier way!

Thanks !
