    Rear Pads Phenolic vs Steel?

    Edit: Front Pads.
    Is there a difference between the pads for phenolic police calipers and civilian caliper pads? Can they interchange? Rock auto specifies their pads phenolic or steel, but these weren't specified. Will these fit a police caliper? Centric 30007480. http://www.rockauto.com/dbphp/prt,142,30007480

    The clips on the pads are different, since the caliper piston bore is different.

      yep. performance difference is minimal at best, but cop pads don't fit on civi calipers or vice versa.

        marquisman is right.
        You can not use phelonic pads in the civi caliper. You would have to swap to the phelonic calipers for that.
        I've seen both police and civi cars with either type installed as original equipment.
        But more CVPI's had phelonic than didn't.

          So how do you tell if you've got phenolic or steel?

              You take the pads off, and the piston side pad will have three "fingers" on the back which hold it in the piston.
              These "fingers" will either be large or small depending on the pistons you have.
              Then just take the pads down to the local parts store and get them to pull a set of pads and match them up.
              And that will tell you if you have phelonic or not. The difference is obvious when you have the two styles side by side.

                small hole = phenolic, large hole = steel. The presence or lack of rust inside the hole is also a tell. The phenolic is black plastic, so it can't rust. Steel is, well, steel.
