Got a 2011 G37S, bought used last year. Rotors were warped but no big deal. Have gotten tired of it now.😠 Still have 6-7 mm left on pads. Had Kauffman Tire turn the front rotors today. I put on new Stop Tech pads and bedded them according to their recommendation. Still have vibration when braking. Kauffman says it felt like the rear rotors were warped when they tested it. But I can't recall ever having warped rear rotors on a car. Should I have them turned? I have new Stop Tech pads for the rear but haven't put on yet. Any ideas?

 

Piston could be seizing

 

I'd check the lines for air bubbles and bleed the brakes

Got the same issue with my rotor from Stop tech. Pass-Front, vibrations came around 900 miles are so. After 1800 miles are so, I ordered a new one. Smh, it doesn't come as a whole unit. Center hub is separate part. I could use the the old one, but decided not to and order the center hub.

 

Hopefully it's not this. During 40k service Infiniti replaced the brake fluid and bled. I already had the vibrations prior to this, but it has gotten worse since then. If I press the brakes harder, needing to stop faster than I anticipated, they actually smooth out. Braking from 65 is rough, but no steering wheel vibration like before the front rotors were turned.

 

Get the rotors checked out to confirm if their warp.

 

new brake pads should never be put on front rotors without resurfacing the rotor surface or replacing an undersize or excessive runout rotor. if i had to make an estimate over 75% of the braking power of a car is done at the front brakes, so it is important the rotor to pad surface is smooth and runout free. in addition i noticed stoptech brake pads are made of harsher brake material which can also cause it to wear the rotor more unevenly. as for rear rotors being warped that also depends on the brake pads used and rotor runout as brake pads wear into them.
