Like everyone is saying OP, find a country road that's pretty straight, none or little traffic. Accelerate to about 40~50mph, brake till about 10mph, accelerate back up to 40 or 50 and repeat for about 5 cycles. Then as the brakes start to heat, you'll smell that brake dust, bring the speed up to about 80 (don't get a ticket!) and do 5 more cycles. DON'T COME TO A STOP OR ANYWHERE YOU NEED TO STOP! Let the brakes cool with a 4 or 5 mile drive with no braking at speed.

Each manufacture of pads/disc's are different and require different run-in procedure so what I stated might not be accurate for yours. But I had alot of sqeeking going on at slow braking speed and some groun from the right/front APracing BBK I got installed and today did exactly this run-in for the second time since I installed the brakes. Their nice and quiet now, grab real good and no groun coming to a stop as I burned off some of that old transfer material on the disc. Good luck. I'm sure it'll be fine.
