Had a large crash which bent front brake lever and made the brake really spongey.

Assumed it would be master cylinder seals so changed them, no better.

Then noticed the calliper pistons weren’t pushing evenly, meaning the pads aren’t pushing square to the disc which is causing the spongey feel. The top piston causes the top half of the pad to push the disc instead of clamping it.

Changed the calliper seals also.

Any ideas?

Id be willing to bet you bent your piston in the master cylinder and since theres air in the line(cause of sponginess) and doesnt have enough pressure to push both pistons.
