At best it will eventually collect the brake dust and clog everything up, at worst it will contaminate the pads themselves.
One of the problems with brakes is that they usually get no attention at all while they still work. It's only when there is a problem that they get looked at. Taking out the pads and cleaning everything up occasionally would ensure you are not faced with a rusted, siezed up brake that's done 40000 miles since someone last touched it.
I know I'm a bit old school, but it works.
Woooh, easy tiger.
Understanding your concern here but.....
I am 47 years old and have been working on cars since I was 15. I have owned souped up Minis, Fords, Vauxhalls, an Alfa GT, Audi Quattro and I have built a Cobra replica, not to mention working on dozens of friends cars and various light commercial vehicles. They have all had brakes with copper grease on the backs of the pads and around the pistons and I have never, ever, ever had any problems with contamination or grease melting and running all over the place. As for getting a bit dusty, thats what Isoproponol is for. You slosh it on and it removes all the grubby grease ready for new.
I will continue to use Copper grease/slip, whatever you want to call it, same thing because it is just better than factory. I also apply it to all the suspension nuts and bolts and any fixing under the car that can corrode.
BTW. I have worked in car plants too and the real reason that they do not apply the stuff on the line is that it is messy, expensive, takes too long to apply and it is almost impossible to maintain the quality of application. the average station time on a car line is just 30 seconds, it just can't be done.
