I recently had nissan install my project mu b-force brake pads on my brembo, and for some reason they re-surfaced the rotors. Well anyway, I'm noticing serious vibrations(like a fast shuttering noise) coming from my rear right of the car (I'd assume the tires or brakes) when I apply 50% brake pressure or more, especially if I'm turning the steering wheel left (for example, pulling into the bottom of my driveway), but I get no feedback from the pedal, so I'd assume it's not the ABS. The vibrations are so rough it vibrate the whole car (rearview mirror etc.). Any input on what this is or how to remedy this issue?

 

did you follow correct break in procedures?

 

Are there still 5 nuts holding that wheel ?

 

ya, dude, this sounds like a serious problem. i would not drive it till you get it figured out.

 

Yes, today I went trought the correct break in procedures again, I'm noticing an improvement in braking, but still noticing this vibrating.

 

Yep, and I just got them re-torqued. Any ideas?

 

is that vibration just a vibrating noise or actual vibration u feel? Try putting some copper paste on the back plates of ur pads, it will reduce the noise.

 

This is both noise AND vibrating, enough to vibrate the inside rear veiw mirror. I followed another bed-in procedure, and it seems like it's gone away, FOR NOW! I'll keep everyone posted. Thanks!

 

My guess is pad is getting stuck a little
maybe you could try using some high temp grease where the pad meets the pad retainer so it slides in and out more easily...can't hurt to do so anyways, just don't get it on the rotor

 

Yea, I brought it to nissan today and took the service manager for a ride. He said he couldn't figure out why this is happening so he asked me to drop i off friday so they can take a look at everything. He said it could "just be the brake pads" which I'm not sure what he means by that. He said "back in his racing days" this meant the pads needed to be replaced, and
I explained to him that I had his dealership install these pads less than 1k miles ago, and I havn't being using them for racing.

 

Ok, so now the deal s the the dealer has told me that the project mu pads expand too much when they heat up, and they don't allow the pad to slide around enough inside the caliper, which inhibit the caliper from closing enough, resulting in this vibrating. So I bought another set of OEM brembo pads and will have them install them. We'll see how this works!

 

if you can't diagnose the problem yourself take it to an independent shop that knows what they are doing. do not take it to a nissan dealer. they are just going to tell you that the aftermarket part is to blame and sell you their own parts.

 

Turns out is was the wheel bearing, nissan replaced it under warranty.

 

What a line of crap.....story goes from brake pad expanding too much to wheel bearing. Not sure I would allow this dealer to touch my car.

Thanks for sharing the story as it is worth knowing.

 

I hear ya, spent $120 or so for nothing. Oh well, on the upside, they gave me a free synthetic oil change and also hook me up with cheap mounting/balancing tires.

 

Dude, I would make them take the OEM pads back and put the Project MU back on for free. You got duped my friend...

 

wow that suck..

 

Yea, I've been using the brembo rears for now, I will have them put the mu's back in, but I will keep the one's bought for when these burn out.

 

Haven't had one problem with my b-force pads yet, I love them for the street and for autocross. Sounds like they were feeding you a line to get you to buy some nissan stuff, I'd stay away from that dealership.

 

Definatly! These pads are excellent. I should have kept Project Mu's name out of this, because I don't want anyone to breeze thru the thread and get any wrong idea's. The b-force are great pads, everything I could ask for. Yea, they fed me a line, and it was a load of bull, but I look at the brightside and at least they fixed the problem without trying to blame it on Auto-xing, or any hard driving for that matter.
