Every once in a while, when braking, I hear and feel a slight grabbing/grinding noise coming from the rear end. Upon acceleration, sometimes the car may, for lack of better words, 'stick' a very slight bit before moving forward normally. After a few seconds of movement, everything turns as it should.

I have purchased a new hardware kit for the rear (and front) brakes and intend to install these this week. The rotors look OK, no major wear or grooves, and the same for the pads. I may install new pads while I am working on the calipers though, especially if one is hanging on me. I checked the parking brake, and it seems to be releasing normally.

Brake fluid was changed out this Spring to the ATE Super Blue.

Am I looking at a bad piston in one of my calipers? Any way that someone knows how to test for this?

Thanks in advance.
