Hmmmm, probably the same you would, a set of calipers would tell how 'thick' they are and the rotor/manual tell you the minimum. I stopped having rotors turned myself as they are pretty cheap (about twice the price of turning for standard ones....sometimes the same price). I have yet to hear of a brake shop breaking in pads for the customer, I think they should ...
I have seen customers get doused with oil and other types of fluids cuz they wanted to "watch". If you think we are just "grease monkeys" come on and try and work in the automotive repair field. You will come to find out it isn't as easy as you think it is. Do you have any idea what new technologies are being installed on cars nowadays or in the future? Did you know that 2002 Caddies come with 22 onboard computers? Do you know about CAN? What about 42 volt electrical systems?
I know a lot about car systems and those that are going to be released, the shop manuals from the factory will tell you just about every diagnostic procedure step by step and the symptoms that cause certain problems...then you just go through the measurements/tests. For many things you will need something better than a code reader, however there are applications for laptops and palm computers that are pretty extensive. A multimeter is important in electrical work.
For the most part all you have to worry about is the cars you own...if it doesn't have a 42V system or HID's or whatever, don't concern yourself with it.
For the guy with the Expedition, what will you do when the air ride suspension doesn't reinflate? Nice to have an SUV that has that expensive to replace hardware. Take it to a mechanic is the proper way to have work done. DIYers don't have what is needed to fix todays vehicles.
Almost all tools are rentable/even the very expensive ones. You have to have half a brain in your head and be semi-mechanically inclined, but so far there hasn't been one project: Home, Computer, Car that I have not been able to tackle with the right tools and books. There are certain things I leave to a mechanic (I would not call even 30% of the 'pros') like my wheel balancing and tire mounting...but even that you can do it yourself just like the old days
🙂 sure it takes a lot longer and you may have to play with it a couple times to get it right...but doable without a computer controlled balancer. Alignments are another thing that's just easier to bring in especially when they have to redo it when it's not right (which it never is it seems...but most can't tell anything about their cars and think things are just the way they are).
The way I look at it is most mechanics were the failures in high school...some were great wrench turners, don't get me wrong...but most of them it was the only road left to go into. Being certified does not make one a good mechanic.
