How much $$ for the front rotors and pads, OEM parts? How much labor for a mechanic to do the work?

 

depends on your make and model.

my 2002 4x4 Blazer has 4 wheel disc brake, I was able to replace all 4 rotors and pads by myself for just under 300.00.

check http://www.autopartswareshouse.com you can get the OEM parts at or below dealership cost.

 

It cost me around 175 to do the fronts on my 96 s-10 2wd with the parts from NAPA, Course I upgraded the pads and rotors from the OEM. Did it myself of course in a little under an hour.
