    Do you own a disc brake bike? The full set of tools for working on them from Park Tool is pretty damn expensive.

 That is only half the tools that they sell for disc brakes.
 So you think that because I have ONE flat mount disc brake bike that I am going to spend over $400 for surfacing tools?
 And my rim brake DeRosa Aluminum main triangle and the Disc Brake DeRosa Idol full carbon are exactly the same weight. So why would I even want to have a dic brake bike except as a test to see if flat surface mount disc bike is any better than the older offset disc brakes? The Merak has carbon wheels and stops a LOT better than the disc. The extra weight of the discs and the constant maintenance show me that they are only for pros and you might notice that manufacturers suddenly are building rim brake bikes again. Do you suppose that there may be a reason for that?
 Also, carbon fiber bikes were used BECAUSE they are light and not because they ride well. Tom Ritchey was interviewed and said that even 1 1/8th steering tubes screws up the comfort of a bike.
 Apparently I filed to be a tester for the Beta software so MY software is different than the stop software with some sort of error in the Average Speed calculation. I know the Beta software is correct because I timed it on a watch.
 I am a real EE unlike Flunky so stop pretending that Flunky saying something means anything at all

Brake mount surface milling to ensure that it is in the correct plane is normal to a framebuilding operation but highly unusual in a service shop. In real life, it just is not a problem.  Could it happen? Probably yes. Have I ever seen such? No.
90% of disc brake issues are air in the system. The rest are mostly worn or contaminated pads
