To fuck a good girl who does not like anal. While doing so, you must place her in the doggy-style position and fuck her vaginally until the moment just before reaching climax. Hence, the name, "brake job". After stopping and making her think you have blown your load already, you must then pull out and slam it in her ass. Remember to be quick...and accurate. Most guys only get one chance. but there have been exceptions. Hold on tight and finish fuckig her until you bust your nut right in her anal cavity. Then, and only then, will you join the ranks of the brake job elite.
Nigga' knew she was a slut, so he had his boy hide in the closet to videotape the attempted brake job. Once he got in her ass, she went crazy and got away. She hit the door quicker than a baby fetus out of my potato gun. He is not a brake job master.

A sexual act involving a man's erect penis, a Boston cream doughnut and fellatio giving a crude resemblance to the mounting of a brake disk on a wheel hub. The doughnut is pressed onto the man's erect penis and once the penis has broken through to the other side fellatio is performed on the now cream covered penis.
"Fuck we were so drunk last night that after we got home from Tim Hortons, River busted out the last Boston cream and gave me the ole Boston Brake job"

If your vehicle develops a brake line leak, the act of merely adding additional brake fluid after the pedal starts to go soft, instead of making proper repairs.
We were so wasted in Cabo that I didn't realize we needed to give the car a Mexican brake job before starting the drive home -- I nearly rear-ended several cars!
