Brake Pulsation Problem

Postby mattchristeson » Thu Nov 21, 2019 7:51 am

Brake Pulsation 2006 M45 Sport.
I am posting a request to other operators, I know the Infiniti M's have brake issues with pulsations in the past. I have replaced the front brakes several times over the last few years. First I dues the Auto zone Brand after not lick with the original equipment replacements. The last time 3 months ago I step up and purchased the Brimbo rotors and pads. after bedding the brakes the pulsation returned. I am getting tired of this. The question is is there convention kit available without spending a boat load ?

Maybe a problem with the master cylinder or something? Have you diagnosed that part of the system? Air in the system?

I have had a LOT of brake problems over all my years owning the car. Until a couple years ago I hadnt found anything that could stand up to my driving, often times within a couple weeks of putting new rotors and pads in the car would feel like things were warped and the pedal could almost feel the high and low spots on rotors.

What finally solved it for me and the issue hasnt come back in a year and a half or so was to get remanufactured calipers from Brakemotive on ebay (looks like PowerStop also sells the exact same ones on autoanything as well), get DBA T3 4000 rotors (only rotors that have ever stood up to the car) and Akebono ceramic brake pads
The DBA rotors were some of the most expensive rotors available for the car which is why it took so long for me to finally give them a shot. Wish I had just gone with them in the first place. ... e-calipers ... ake-rotors ... ake-rotors

While you are removing calipers from the car you should also completely flush your brake fluid since you are going to have to let it drain somewhat anyway with calipers out. ... rake-fluid

I have a pulsation even after getting brand new Centric rotors and Stoptech Sport pads for the front. I took the car for another issue to a mechanic and he also noticed that the rear rotors are beyond their run out so this pulsation is really coming from the rear he says.

I will be replacing the rears with brand new Centric blanks and Stop tech Sport pads to match the front. I will report back to this

Thanks for the info. I have had similar problems throughout the 13 years I have owned this car. I typically just replace rotors, pad and flush every 1.5 years. I am little annoyed by it. i will give the above recommendation a shot and get back to everyone.
