This is actually a common question I've heard at a number of service seminars and meetings I have attended, so I guess I'll give you my thoughts based on what I've heard.
#1: The customer isn't charged for this inspection because none of your after market competitors would. Let's not do anything to perpetuate the idea that dealerships are more expensive. I personally consider it in the smae light as I would advertising or other marketing expense.
#2: The key last word above is "expense." I believe that you should pay your techs and I would set some expectations of what that would include. Lloyd Schiller is big on saying that if you don't pay the techs you can't control the quality. I agree, asking someone to do something for free will net you mixed results. Especially if the techs believe that your advisor can't turn their "freebie" inspection into a sale. Or, if you have a situation where the brake work would be turned over to another tech.
I expect that a brake inspection would include the following; inspecting and measuring brake shoes, pads, discs and drums. Checking calipers, cylinders, the master cylinder and all the lines and hoses. A pre-printed check sheet is great here. I personally hate guesses on remaining brake life, because if you're wrong you destroy your credibility with customers. I will literally find out how thick a pad lining is to begin with, and then divide that out by the remaining usable thickness and the vehicle's mileage to get a better estimate of remaining brake life.
To goose the customer, I'll offer a deal to do the job today. Say the pads have 15% left and the customer has 21,000 miles, meaning they can expect to *need* to replace these pads at 24,700 miles. I'll say something like, normally our brake service would be $179, but since the car is already in, an R.O. is written and the wheels are all off I'd like to save you a return visit and extra hassle by doing the job for $119 today for you.
