So you think that everyone who is a mechanic is a high school drop out and only spends the money on beer and dope..wow that's a stereotype if I've ever heard one and just plain trash. I know someone who used to be a mechanic who did graduate and had his own house, supported himself and saved his money. So now he has an even better job paying way above the min. wage and his house is beyond beatiful. Oh not to mention the wife and kids that he now supports. So there goes your assumptions of a mechanic. Or better yet, why don't you just change your brakes yourself and then you won't have to have some "high school drop out" tell you when you need to. Problem solved!
