Found this on my drivers side floor - any ideas?

When I was checking out my “clunk” brake pedal noise I replaced my brake light switch and also bought a new spring in case I needed it. I had to go out and search the garage but finally found it. That little piece of rubber/plastic just slides inside the brake pedal return spring and doesn’t do squat in my opinion, I was able to pull it out from the inside of the spring without any trouble.
I do believe that’s what you have there, here’s a picture.

 

Forgot about the sweet Captain Planet mullet. Holy shiz that’s a strong one.

 

So, Toyota discontinued the glovebox organizer to save a few dollars, but keep the butt plug...?

 

It's supposed to stop the noise from the pedal return spring. On some cars the noise is more noticeable.

 

If your truck was built in Mexico a worker throws it in the truck before the truck will go out for shipping. It is called a Yankee confusion Plug. If you truck was built in Texas the Yankee Plug was probably missing since they did not could figure out what it is for.

 

Bwaaaahahaha, butt did anyone who’s found the “plug” give it a good sniff?

 

I don’t understand the joke, Gringo

 

I believe it’s a bleach drinkers condom.

 

I suspected it had something to do with the brake return spring but didn't didn't know how it fit, and honestly I didn't give it too much thought. I have a very faint "tung" sound when I first mash down the brake pedal when starting.

 

Same here.
