Default stupid brake question

What is the best way to brake in new pads on a freshly re-surfaced rotor?
I have always thought that its best to be gentle for a few hundred miles.
Other people say you need to do a few hard stops from speed right away.

Usually it's something to the extent of 5 or 6 moderate braking without stopping and then 5 or 6 hard stops without stopping. Let cool for a few hours, preferably over night.

Do a search and you'll find more indepth answers.

I just found these in my favorites:

So if that is not at all what I did, should I resurface and start over? Can I do that with the old pads?

I assume you did a different break-in procedure? It may not make too much, if any, of a difference. It actually took my rotors/pads a while to "even" out - or it was my wheels.

What procedure did you do? And you may not be able to resurface the rotors.

I just did easy around-town driving for about two weeks.

The rotors have been re-surfaced only once, why would they not be good for another go?
Thanks for your replys.

It really depends on how much material you have left; but from what I've read, the general concensous is turn 'em once then toss 'em. I'd say if you're not getting any vibrations then don't worry about it.

I STRONGLY suggest you read this article from Stoptech:
http://www.stoptech.com/whitep...h.htm

One thing that it suggests is to use garnet paper to clean the surface of the rotor in prepartion for bedding in new pads, or to get rid of uneven material deposit. I have never seen garnet paper before, but was able to find some on 3M's website. Do they sell garnet paper at home deopt?
I had previously just used emery paper on my rotors, but Stoptech says this is a big no-no,,, and can even make the situation worse!

So, for your situation I would
1. Read this article
2. Find some garnet paper and buff your rotors.
3. Start anew with the bed in process.

The purpose of bedding in your brakes (the procedure clm describes, which should get them REALLY HOT, and then letting them cool overnight) is to apply a uniform surface of brake pad material onto the surface of the rotor. This is also described on the Stoptech website.

If you've been driving easy on your brakes, you probably didn't get them hot, so there's no material on the surface. No need to emery paper or anything; just go out and follow the bedding procedure now.

The bedding procedure is primarily for taking the car on the track (or driving like you were). If you're only driving moderately on the street, you probably don't even need it...
