Technical 57 Pontiac Disc Brake Question

Discussion in 'The Hokey Ass Message Board' started by rarerodder, Jan 30, 2016.

  1. Can anyone tell me if it is ok to reverse the calipers on front disc brakes to move them to the front of the rotors rather than the rear? If this is ok to do, it would really solve an interference problem I have on my 57 Pontiac project. This is a disc conversion kit for my Pontiac in which the caliper/brackets normally mount on rear of spindles. Problem is I'm also using drop uprights which require bending my steering arms, but the caliper brackets are in the way of bending the arms. But, if it's ok to run calipers on the front of rotor, then I would be reversing the caliper brackets to bolt to the front of the spindles and problem would be solved. Someone enlighten me?

    You'll find them in either location on late model cars, just make sure the bleeder is on the top.

    Do it, I bought a disc brake kit from Danchuk for my '57 Bel Air and the brackets supplied put the calipers toward the front. Just make sure the bleeder valves are at the top, with my kit the left caliper became the right caliper and vice versa.


    The calipers don't care where they're mounted, the OEMs put them wherever they want them.
     
  4. Thanks guys, I couldn't see how it would matter where they were mounted but your confirmations make me feel better doing it.

    I'm planning same conversion on my 57 Pontiac, good information. Have you considered swapping sides on on the steering arms so the tierod ends are bolted from the underside of the steering arms, thus not having to bend the arms so much?
