oh, and it's likely you damaged the calipers by compressing the pistons with a c clamp on the outer edge of the piston... could have pressed them in crossways and damaged both the piston and the sleeve/seal.

Better double check. I think the FSM calls for pressure bleeding an ABS system at around 20 psi.

Make sure the rubber caps behind the brake fluid reservoir cap hold tight. Old ones can leak with the reservoir under pressure.
