brake bleeding firm now spongie.

Since you said it's only happening after you bleed the R/F caliper I'd start there. Take a good hard look at it to make sure there is no binding, the pads fit correctly & are seated the slides move freely & the piston isn't retracting into its bore after the pedal is released. Any unwanted movement in the caliper will cause a spongy pedal. It should feel good & tight when you grab it & try to slide or shake it once it's been bled. I've seen also seen pads that had little aligning nubs on them that were to fit other models interfere with the piston & cause it to feel like air in the system. Also make sure the rotors are in good condition & the pad isn't riding on the edge of the rotor. May sound stupid but, the brake hoses aren't kinked or twisted are they?
