2001 Lexus Is300, changed front calipers, bled the brakes still have a spongy pedal, any suggestions?

 

What was your bleeding process??

Assuming this works on 300;
2 people: press pedal, hold, open bleeder, purge. Close bleeder, release pedal. Do all 4 corners. Do so until fluid is clear and no bubbles are seen.
If you run the MC dry, you start over.

 

first off welcome. had a spongy brake issue before. it took me forever to resolve and after new rotors, pads, brake lines, and bleeding numerous times, it wound up to be stuck/lazy caliper
