I just noticed today my brake pedal has ~10mm side to side play. I'm probably paranoid and it's most likely normal. The idea of my brake pedal coming when I need it is scary however so I just wanted to see what kind of side to side play you guys have.

Normally I would look at the pivot point, but it's behind the steering so can't see.

 

There's a clevis pin and a plastic bushing for the pivot, they both can wear a decent amount (IIRC, same setup as the clutch pedal, if you've had one of those out).

I wouldn't worry too much about it, honestly.
