Brakes on 2006 Acura TSX

When changing the rear brakes on my Acura is there a release for the cylinder? The cylinder does not seem to go back far enough for me to get the pads in there. Thanks in advance!!

Hi there, you need to buy a piston reset tool,

Do you have rear disc brakes? If so the pistons have to be turned back into the calipers. Do your self a favor, get a repair manual, Haynes, Chilton's, what ever before you really mess something up or hurt yourself.
