Excessive pedal travel on rebuilt S callipers, but car stops fine Options

[phillstek]

Just finished rebuilding the front callipers with new pistons and seals. Bled them 3 times including power bleeding but the pedal just won't come up. It feels like half the available pedal travel is in free motion before the brakes engage.

Car stops without pulling or locking up and the pedal pressure holds when stomping on them but I would prefer to have the pedal engage pretty much as soon as I hit them.

Any suggestions on possible cause and what I need to do to fix it?

Thanks

Yup:

1. Take out the knockback mechanisms.
2. Check the pad clearance on the S-Calipers. New seals will pull the pistons back aggressively. To verify, check the clearance of the pad and rotor.
3. Bed the pads. Multiple times. This will be good for the pads, rotors and the seals. It will help break in the seals.

Once the seals begin to break in your pedal will come back up.
