Bedding in new brakes

[superfans]

How long does it take to "bed-in" new brakes? 200-300 miles? Before the brakes are fully "bed-in", will they sometimes create slight creaking noises? What is the proper procedure to bed in new brakes?

If there are streaks on the surface of the rear brake discs (only the rear discs), could that be rust/dirt/dusts or something is wrong with the discs? Thanks.

Check your thread over on Rennlist. I posted an answer there for you. Hope it helps.

Take the car out and get to an area where you can accelerate and brake repeatedly. Get the car up to 50 or so and then evenly apply the brakes until almost stopped. DO NOT keep you foot on the brake pedal when you are stopped (unless you HAVE to). Repeat several times, inceasing the pressure you apply to the brake pedal. A couple of hard braking applications will complete the break in. Now enjoy the car.

You can also drive the car while applying the barkes lightly while driving. Keep doing this for several miles increasing the pressure to the pedal. The idea is to get the brakes hot and seated without letting the pads sit still against the rotor. No further break in is necessary.

FYI.. on the '06 997 (mine's an S), you can't apply brake pedal pressure while pressing the accelerator in gear - I'm guessing it's because of the electronic throttle control. If I am driving along and hit the brake pedal with my left foot, the throttle backs off. ;)

Another of the many drawbacks of computer controls. Simply apply the brakes from speed down to near stop a few times and you'll be done.
