A year ago or so I put the Fiero Store's Grand Am brake upgrade on my 86 SE, and I moved the old front calipers to the rear (because the parking brake never worked anyway). But I wanted vented rotors on the rear also, and I wanted a working e-brake. So I recently did the Grand Am rotor/Seville caliper upgrade on the rear. The general procedure is written up on Pennock's
here, and toward the end of that thread, you can read about my variation, with some pictures.
