My front brake pads are low and need to be.

Brake work is dependent on several factors, are the rotors worn too thin or are they warped? If not you might be OK to just replace the pads and be done with it. Either way you are looking at about an hour and a half of labor at whatever hourly rate and cost of pads, rotors and a brake pad sensor, usually about 400 bucks an axle to have it done completely and with all new parts and labor.
