Took the servo out to replace it. Now when I've come to put the clevis pin into the brake pedal the pedal now sits too far away from the brake switch thus the brake lights are always on. Pedal seems to be sitting higher than normal too, I know the brake pedal should sit a tiny bit higher.
Took some photo's to try and show what I mean, but the aren't brilliant.
Clevis pin out so pedal isn't connected to the Servo plunger.

Clevis pin in so pedal is connected to the Servo plunger.

There's approx 10-15mm gap now that I can't account for. Checked that I haven't moved the switch somehow, even put the old servo back in to check and it's the same. Is the a rubber bung or something I've knocked off?
Any help greatly appreciated.
