New Pads & New Rotors

[DSMKevan]

I just got some brembo blanks and some Axxis Metalmaster Pads for the front brakes, as well as blank generic rotors for the rear. What is the proper "break in" procedure? Should I install the brembo rotors with the old pads to "break them in" for awhile(if so, how long?)? Or should I simply install the new rotors and new pads at the same time?

As for breaking in the pads, do the Axxis Metalmasters respond well to bedding? If so, what is the proper procedure for bedding them? I used this procedure when I bedded my "regular" pads: http://www.zeckhausen.com/bedding_in_brakes.htm

Those bedding and breaking in procedures seem like a major PITA. Just take it easy on them for a few hundred miles, then progressively start using them more heavily. This does the same thing as the bedding/break in procedures, but it just takes a little longer.

Thanks for the info. But what Im really trying to figure out is: Should I install the brembo rotors with the old pads to "break them in" for awhile(if so, how long?)? Or should I simply install the new rotors and new pads at the same time?

If it helps, When I put my Baer kit on I had new rotors and pads and bedded them all at the same time. I had no issues.

There was a good article on bedding in the last issue of SportsCar (the SCCA magazine). The specific recommendation varies across vendos, but all agree that you should do some medium-to-hard slops to get them warmed up, let them cool down, and then do it again. The one specific that all agreed on was to never be on the brakes with the car not rolling and the rotors hots, especially not early on.

Bedding transfers some pad material to the rotor and also rids some of the "juice" in the pad (which can cause "green fade" for a wile). You don't want the bedding process to be by chance, so you want to go out and bed them, not just drive around normally for a few days.

Note: if Todd comes on here and contradicts anything above, take his advice, not mine.

Right, if you look on the site I posted more, theres a lot more in depth information. http://www.stoptech.com/whitepapers/bedintheory.htm

Pretty much says the same thing you said. I understand the bedding process almost completely, I was just wondering if there are ANY consequences to installing new pads and rotors at the same time (with bedding of course).

Sounds like a bunch of work for nothing if you aren't going to be using the car for autoX or true high performance applications. I just put Brembos with new pads on the front of my car and I followed Brembo's break-in policy of around 120 kilometers with light braking and only pushing on the pedal for 3 second pumps and staying off the ABS. Brakes feel great now, but that may also be from replacing a dead caliper.

I wonder how many more people are going to drop into this thread to talk you out of bedding your pads and seasoning your rotor.

I don't think anyone is talking him out of it, I just said there is an easier way about doing this process without following the instructions for bedding and seasoning rotors. Those processes are only needed if you want to season them quickly so you can use them harder sooner, like if you had a track event coming up the next day or something. Being easy on them for a while and then progressively using them harder after a couple hundred miles has the same effect. That is what I read on Baer's instruction when I installed my kit.

Actually the break in process I did for my older pads was pretty easy, it only took me like an hour and it was a pretty fun drive I might add

Ill decide what to do when I actually get my pads :laugh:
