Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Just replaced all four rotors and new pads, wondering how long a break in period do they need. Service manager said 1000km? seems excessive, no?

POST 2Original post

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. I currently have 45,000 on my orginal brakes.

POST 5 / ORIGINAL POSTEROriginal post

Don't mean to doubt your advice, I do appreciate, would feel better if I got some more opinions please before I go out and do what u describe. Cheers

POST 6Original post

Ok, I'm going out to put more miles on my already 45,000 miles brakes.

POST 8Original post

What was suggested above does work, but make sure you are not applying too much pressure. Make sure that the pressure is even and light. 1000Km is really long, I would say about 300Km of normal light driving should do the trick. The key is to let the pads and rotor set in to each other slowly. Do not slam your brake unless you have to.

POST 9Original post

Just do it for a few miles and you are set. They do not sit any better after 100 miles than they do after 10 if broken in properly. But then there are those that will spend the first 2,000 - 3,000 miles breaking in their engine too, which is not necessary. So either spend your time unnecessarily breaking in the brakes, or spend it enjoying the car. I think that having 45,000 hard miles on the orginal brakes supports the procedure I outlined above.

Here are a couple of great articles on the bedding in process: http://www.stoptech.com/whitepapers/bedintheory.htm http://www.zeckhausen.com/bedding_in_brakes.htm

thx brian, very informative

POST 13Original post

Interesting. After reading the links bet posted, I would say that 1999porsche911's instructions where just about spot on the nail.

POST 14 / ORIGINAL POSTEROriginal post

Yes I have already followed them thanks 1999porsche911!!!

POST 15Original post

I concur with this procedure. Do it all the time for my race pads. Take it easy for the first 50 miles or so and do what 1999 said. DO NOT keep your foot on the brake when coming to a stop (of course like he said, you have to). You brakes will be fine after this bedding session. Chad

POST 16Original post

My experience validates this "bedding in" procedure. Stoptech, Brembo and Pagid all recommend this procedure. I was victim of a Mercedes dealer not knowing anything about it--it cost me two, yes, two sets of front rotors. Moved on to a 911....
