Does the rear caliper have......
 

brake dampers?

The front caliper has a one piece brake damper (one for each brake pad) that fits into the two brake pistons and adheres to the back of brake pad. No issue with those and replacements are available from Pelican.

When I removed the pads on the rear caliper, I see that each brake piston has a round, clip- in brake damper?? Total of 4 for each caliper. I don't see this item at Pelican or SunCoast. So that I don't have to go buy them at the dealership, who carries these items? Thanks.

I just found them on SunCoast. I should have searched better. Sorry for the message.
