SSBC front disk brake converion on 67 cuda, no pressure, HELP

Sounds like the pistons are pushed to far in the caliper housing.Remove the bleeder screw and push in compressed air with a air compressor.This will push the pistons out and seat the pads against the rotor.Insert the bleeder screw and re-bleed.

ps:The pistons should be coated with clean brake fluid before being installed in the caliper.

Hope this helps.
