Hey guys
do I need to replace my rotors if my brake pads are being replaced? My car has around 16k miles. If so, can you guys recommend some good brake pads and rotors. I was thinking of project mu ns and I don't know about the rotors.
thanks guys!

Someone correct me if I am wrong, but I thought the general guideline is 2 pads swaps per 1 rotor swap?

Just take the wheel off and measure the rotors with callipers ( you can buy from any auto shop) 34mm new 31mm replace fronts

^^^^Rotors should never be machined (turned). If they are grooved replace them. If there is pad deposits, whey can be gently sanded off. Thickness measurements, as mentioned, need to be done to determine when to replace. Proper bedding of the new pads is of utmost importance.

In my "personal" opinion, I'd say NO. Unless you're experiencing any type of shudder or braking difficulty Pads alone is fine.

Heck, I'm seeking for new pads right now that wont produce the ridiculous amount of Brake Dust these OEM Pads do!

There's a service bulletin that will have the dealer replace your original pads (assuming this hasn't already happened) with ones that don't put out as much dust and won't squeal during low speed braking.

In theory you lose a small amount of stopping performance, but reduces dust and noise, at no cost to you if you qualify.

Here's a thread with the bulletin, check post #46:

no you measure the rotors thickness there are minimum thickness specs. If too thin, you replace. I have cars that are over 100k miles on original rotors and still thick enough

GunnyFitz

LOL. Cracking myself up because I was just about to reply that no one in that thread noted the actual TSB! I literally wen thru every post until I found it on #46, THEN looked at the last comment you made! Yep- #46 is correct!

May as well ask you here, as I was just offered a pretty good deal on replacement pads. Let me know if any of this is both legit and what I seek...
(NOT Tracking whatsoever!)

"Those Endless MX72 are phenomenal pads but aggressive. - If you're just street driving the car with no track use then the new Project Mu PS compound or the Carbotech 1521 compound will be the best option for you. .....the new Project Mu compound is better as opposed to the Carbtoech pads because the quality control is a bit better with those. ...Carbotech has again increased the price because there have been so many issues
...List price on the Project Mu PS compound is $486 for the front and $281 for the rears."

Esseintially than- Is Carbotech or Project Mu a better choice? (Sorry "Spam" I didn't mean to Hijack your thread!)

PS. Thanks again and here is that TSB if anyone needs it. (Sure is an Old One though huh?)

Does anyone know the part numbers for the different compounds? I don't have noise, but a ton of dust. My closest dealer is over an hr away and I'd like to check my pad part numbers before contacting them.

Keep in mind, there is a trade off. The OEM pads the car comes with, are high friction pads that give the best stopping power under heavy use. While the TSB pads would have less squeals and dust, the stopping power will not nearly be as good. Some people say, if you don't track the car, it is not an issue, but for others like me, I choose to stick with what originally was designed for the car.

^^^^What you say is true, BUT but there are aftermarket pads that will have better bite and performance than stock pads. like Project Mu HC+800 or Ferodo DS2500 pads. AMHIK.

Yeah, I was just comparing OEM and TSB pads. There is a trade-off there. The TSB pads while having less dust, don't have as good a stopping power as the OEM brakes especially repeated heavy braking.

GunnyFitz

THIS is what I was trying to say.
OEM - SHOW-EM = The Dust is CRAZY Rolla!

I just want these things GONE. Spoken w Speed Freak on these "Alternatives" Lou is talking about.

I'll wait until my first Service at 5k miles, or come late Sept when I swap out my Bling Wheels with Stock for a 12 hr drive. One deep a** pothole and these suckers will end up crooked as the Administration!

Were RCF's after 2015 made with these "high friction" pads, or the ones that produce less brake dust? This year, my dealership for my 2015 RCF, replaced brake pads using the "high friction" pads (according to the part numbers on the receipt).

Are 2016, and later year RCF's, still coming from the factory with brake pads that may give excessive squeal and dust?
