I should know this but, I'm going to ask anyway. Did all 69's have four piston calipers on the front? And are the Z/28 rotors larger than the SS or Std. camaro?

Many 69 Camaros had drum brakes front and back. If you are refering to just the ones that came with disc brakes, the calipers and the rotors are the same for the Z/28, SS, and the standard Camaro.

All 1969 Camaros with power front disc brakes used the same braking components regardless of engine. All were equipped with single-piston calipers. Four-piston calipers were phased out at the end of 1968 production.

There were engineering changes to the J50/J52 system through the model year that are also unrelated to the engine.

Except the JL8 4 wheel disc brake option, that came with 4 piston calipers front and rear and the rotors were bigger(11.75") and thicker(1.25") as well. If you're looking a 69 Camaro with 4 piston calipers, get the casting #'s off the calipers and we can help determine if they might be original or not.
