Weird feel to clutch, brake??

Hi, just wondering why my clutch feels weird? It feels a little unstable and sometimes when I release the clutch, I think... I think I can feel the brake pedal slightly move against my foot while its on the accelerator??? I dunno, I can't really describe it better than that...

Anyone have any idea what the go is? I've driven stick my whole driving life...
I've read some stuff about the cdv delete, but would that explain it?

So the brake pedal moves over and brushes your foot? And the clutch pedal moves laterally as well? Just trying to understand.

Yep sounds weird, but that's pretty much it, I've been down there while the car is stationary and its all solid.. Really strange feeling....

This does sound odd. So you know, the clutch and brake share the same reservoir/hydraulic system. It's doubtful, but possibly and air bubble in the system?

That would be my guess. Try bleeding your brakes and clutch.

The accelerator and brake pedals are very close together by design and for obvious reasons. Often if I am wearing wide sneakers (trail runners) when I'm on the brakes I will often be rubbing the accelerator.

Stick a GOPro or iPhone down there and take a video

I know sometimes it also feels like the clutch is touching the floor mat. I'll take it out first see if that changes anything and ill barefoot it so I can remove the sneakers from the equation.

You're a "barefooter" too? I love it, can't wait for the warmer weather to show up here on the northeast. It took a while for me to adapt to barefootin' the gas pedal.
