It seems that there are two opinions how to bed in new set of rotors and pads - slow and agressive. Now, which one is the better one for Brembo blanks + performance pads?
Please note that this is for both new rotors AND pads fitted together.

Slow bedding
Most of the brake companies and people recommend light use for the first XXX miles, than you can use them hard.

Aggressive bedding
Stoptech in its FAQ recommends doing of 10 hard stops from 60-10mph using 80-90% of braking immediatelly after new discs and pads are installed.

Which method do you use and what are the results? I mean, if I use the aggressive method, will my rotors warp immediatelly?

I would use this method recommended by Cobalt Friction if your pads did not come with specific instructions...

I have heard that it is not a good idea to bed in pads on rotors that you are also seasoning. Here are some goood links with nice information:

Thank you for the links guys, but I already know them. The instructions of bedding in pads are usually very similar and simple to do, everything is clear here. The problem is, that for example Stoptech and Baer differ in the bedding of rotors. Stoptech says go ahead, bed in only the pads and don't care of the discs. Baer says be light on the brakes for XX miles to bed in the rotors and then bed in the pads. Now which one is the right one? Which method do you use?

 

I've tried both and I cant notice a difference between the two in pad/rotor life.

OK, so you just fitted new discs and new pads and made 10 hard stops immediatelly? You discs didn't warp compared to the slow bedding? Thanks for the info, that's what I need to know.

Well I did the bedding procedure, yes... never had any problem doing it that way.

Same here.

Unless I am going to have to use the pads/rotors right away, I would normally elect the slow method because...well, it's simply less offensive to law enforcement officials.

 

I use the aggressive procedure (like .RJ, just as recommended by Stoptech and by Cobalt Friction) and I have experienced no problems (warping or otherwise) as a result (also like .RJ).

"Bedding pads" and "bedding rotors" are the same thing - getting the brakes hot and allowing them to cool down according to a standard procedure, so that a uniform layer of pad material is applied to the surface of the rotor. This prevents shudder from uneven deposits of pad material which might otherwise develop, particularly when the brakes are used hard (such as on the track).

In the past, when I have not followed an aggressive bedding procedure and simply used the brakes gently on the street for the first few hundred miles, they were more likely to subsequently develop shudder.

HTH

 

I have also used the "aggressive" bedding in procedure described on the cobaltfriction web link more than once, and it seems to work well for most types of agressive street pads.

Actually did it last night (installed a fresh set of autozone rotors and cobalt GT sport pads). That was fun in the rain

*Note - I recommend finding a LARGE empty area for this procedure, such as an industrial park or empty parking lot - wouldn't want to get arrested or crash into anything...

 

Great, so let's assume that the aggressive method works and is safe to the rotors. Now how exactly do you do the bedding:

1) You have cold brakes (discs + pads), go 60mph and push the pedal to about 80-90% (maximum before ABS) without any initial rotor heating (and repeat 10x).
or
2) You heat the discs and pads little first, then accelerate to 60mph and apply the brakes hard (and repeat 10x)?

How do your discs look like after the bedding in (10x hard stops from 60mph)? Are the machining marks still visible or is the disc flat? For example Brembo blanks have quite deep machine marks from lathe, other discs can be grinded so the "scratchs" are very tiny. Are the machining "scratches" disappeared after the bedding?

You're thinking about this way too much... you've been given two links to how to do it. You've acknowledged that you've read them...

Just do it.

I understand that I go really deep with questions, but I haven't found any thread about the "aggressive bedding experiences", so we can create one here now . Why not to ask about every detail, so everybody else can find it here in the future? If one doesn't want to answer, he doesn't have to.

There's no need to.

The directions are very clear and they work.

 

nsxtasy,

I have searched little bit more over the Internet and found your excelent posts on nsxprime.com: http://www.nsxprime.com/forums...40059

I just want to thank you, this is the perfect explanation of all the details during bedding in. Anyway, many people keep saying to bed the rotors with old pads carefully before the hard 60mph braking, but I will go this aggressive way. I hope my rotors will glow like on my avatar in the end of the bedding

PS: at least I hope that nsxtasy on ht = nsxtasy on nsxprime

Thanks to all,
Petr

True.

 

I've used stoptech's agressive technique on Brembo blanks/axxis pads and there are no signs of warping on them so far (nearly 2000 miles on this daily driver)

And funny enough I looked at that link above in NSXprime and who else do I see but Larry Bastanza

Please do me a favor Ken, the next time you talk to him, tell him I said hi (use my real name of course) and tell him I'm sorry I never got back to him before now, I lost his number. Also let him know that my R is doing fine, no more brake issues, and tell him my offer to help place his son at a local restaurant or club job or internship is still open

Small world.

Thanks for sharing your results

 

petrv: here's a link to a thread regarding *where* are good places to do the bedding procedure - https://honda-tech.com/zerothread?id=1110240

hope it helps out. listen to these guys, they know their stuff!

Thanks, excellent and helpful thread (except of some people trying to ghet the thread bad way).

Don't worry, I know nsxtasy, .RJ etc know their stuff...

dood. just get in your Hype R. drive to a safe place, when you get to that safe place get the Hype R moving to about 60 and then begin your method. Not that hard.

 

great thread!
