Brake nerve 

When someone is braking while driving for what looks like for no reason, we can only attribute this as a side effect of picking their nose so hard and deep that they hit their "brake nerve".

"What's this fucker doing? He must have hit his brake nerve."

Brake his Grandpa's Cane 

A phase invented for females to use instead of Smash the Granny, meaning to have sex, fuck, bonk or shag.

"Are you going to have fun with that guy tonight"
"Yeah, I'm going to Brake his Grandpa's Cane"

"He said he wanted to Smash the Granny out of me, what he didnt expect was for me to Brake his Grandpa's cane before he could even undo my braC

brake up 

It is for when two folks are in a relationship and something needs to change, or slow down, or whatever and needs to be fixed to prevent someone from getting slaughtered.
Not to be confused with "break up".

"Hey, slow down lady. You are being all whiny, we need to brake up so you wont be all kinds of squeaky anymore."

Brake-tapper 

The brake-tapper is a particularly aggressive and/or fast driver who comes barreling up to the car ahead of him/her and tail gates at such a close proximity that he/she ends up tapping the brakes to avoid rear-ending the poor schlub in front. This usually goes on until one party turns.
Followers behind the brake-tapper should take note that just because he/she is hitting his/her brakes, those at a safe distance don't necessarily even need to brake themselves. It is especially annoying and careful attention is imperative.

You: What the damn, why are we braking?
Me: We aren't. That guy in front of us is just a basement-dwelling neckbearded brake-tapper.

brake test

Speeding in front of another driver and then immediately applying the brake, causing this driver to have to stop quickly as well - testing the brakes on their car while evening the score. Usually used as a retaliatory measure against a stupid driver who has pissed you off. Works well on hypermilers.
As a side note - Brake testing should under no circumstances be performed while your wife/girlfriend is in the car. They don't appreciate the need for immediate retribution.

"Kevin brake tested the fuck out of that guy!"

Kevin said "I'm gonna brake test the fuck out of this guy - hang on!"

brake pedaller

Anyone who constantly feels they have the need to use the brakes on their cars.

Mostly,
-old people
-cautious drivers
- the occasional drunk

These types of people use the brakes anywhere where:
-there is no traffic light
-there is no stop sign
-there's nobody around (See brake nazi)
-on the fast lane of major highways (i.e. I-95)

One other way to spot this driver is that they:
-never follow the speed limit (they drive 45 in a 50)
-they're have a lot of cars behind them
-they drive either a "fuel efficient" car or a duster
-are probably lost

tips to get past them
-just cut a lane over when you get the chance and have your foot to the floor when you pass.

Jimbo: "Damn man, can this guy ever pick up the pace. WHY THE HELL IS HE ON THE BRAKES!?"

Nate: "Dude, Calm down. It's a brake pedaller. we'll pass him when we get the chance."
