Raybestos Rotors + Project Mu NS400 Brake pads Review
I'm going to make this short and sweet...Complete waste of money! Yeah It was half the cost of OEM or less but this combo is terrible. The pads fade far too easily and stopping power is not much better than fully worn down stock pads and rotors. As the saying goes...You get what you pay for! Never again am I going to settle for aftermarket pads and rotors and I don't think any of you should either unless you totally drive like an old lady, then you won't feel the difference.
I remember someones wife here ranting about the NS400's a couple weeks ago and even though I didn't listen and got them anyways, she was right. These pads are terrible on the street...I would think they would be much worse for the track and life threatening if you go by what Project Mu advertises.
Ok I'm done with my rant...Just wanted to warn anyone that likes to drive spiritidly and hopefully this helps anyone else considering this combo. And yes the pads were bedded and broken in properly.

Long story short, these are street pads, not track pads. If you're driving at limits that cause these pads to fail, then I would suggest you need to take that kind of driving to the track... and then get the right pads for that.

Did you clean up the rotors with brake cleaner before installing? Did you touch the pads with your bare hands by chance before you installed them?
New rotors usually have a type of oil that is put on after the manufacturing process. This oil can contaminate the pads too.

A member pointed this out to us -
In my opinion what Patrick and Vbb are stating here correct - (If the pads were purchased for street use):
Quick statement - there is an oil deposited on new rotors, especially semi decent quality rotors, when packaged, that keeps the rotors from rusting while they are transported across countries or sitting on the shelf. This is again common with almost any off the shelf rotor.
Additionally you will need to lay a transfer layer (google "bedding in pads") onto a new rotor so you can get decent friction between the two surfaces (google "creating a transfer layer on to rotor").
We really feel for you as you did not get an opportunity to enjoy these pads yet, if the above did not apply and perhaps you have some other scenario (brakes need to be bled, low fluid in the reservoir, etc). it is best to check those before attempting to burnish the rotors.
For track use its generally recommended that you start with either Project Mu Club Racers, Carbotech XP10/12, Performance Friction 08, etc. depending on your abilities and the tire compound/contact patch size that you are using. There are other pads like Ferodo DS2500 that can work with hard street/hill use as well, and Endless has an MXRS pad or equivalent that would work for you as well.
Let us know some additional information so people can at least learn from your use or help you along!
Best Regards-

I also have Mu's and I'm loving them compared to OEM pads.
At first I thought maybe its the combination with the rotors but from the feedback above that doesn't seem to be the issue.
Hope you manage to figure out whats causing you this problem, but for me personally I'm going Mu all the way.

Raybestos rotors are made by Brembo. It's not the rotors.
Don't use Project Mu NS400 Street pads on the track. Done and done.

Hard to beat the OEM Jurid brake pads stopping (bite) for street use..
BUT just can’t deal with the messy & corrosive dust they make..
No complaints from me on the Project Mu's... And I just recently installed a second set of front pads.
My first set last well over 50k miles.. AND they did not chew up my new OEM Rotors..
