problem before:
steering wheel was shaking during high speed braking.

solution before:
front rotors were bend, replaced for new ones, problem was gone!!

problem now:
after about 2k-3k miles of the new rotors, steering wheel started shaking again during high speed braking and i could hear the very deep braking sound

sloution now:
could be the pads??? or rotors again??? or something else??

thanks

 

If the rotors a new "factory" it could be that they are bent .....but that's a major problem with the Max rotors.. if you look at them the will bend........ Also it could be Balancing...try balancing the wheels... that should help...... but if the shaking continues.... replace the rotors with PowerSlot.. they worked for me....

 

im gonna go with wheels needing to be balanced

 

yikes

it sounds like your rotors warped again, that's no good...
Try re-tightening your lugnuts with a torque wrench? Maybe they're overtorquing or torquing the lugnuts unevenly (doing some tight, some loose, etc.)...

If the wheels haven't been balanced lately OR you haven't had an alignment recently, get both of those done.

 

Did you reuse the old pads when you replaced the rotors?

 

Probably not because problem came after 2k-3k miles

 

Wasn't there a TSB regarding this problem? The rotors on our cars warp easily, but I remember somebody saying that the hub the rotors are attached to may actually warp, which causes new or newly machined rotors to warp more quickly than they should.

 

Never heard that before. The hub face warped? Hub face is thicker than the face that the lugs go through on the rotor. I doubt that the hub is warped.

 

This is the TSB: http://apollo799.50megs.com/Maxima/Brake%201.htm

It does not mention the hub being warped however one can only speculate so many causes as to why Nissan would call for an on-car vs off-car lathe.

 

yes i reused the old pads after i replaced the new drilled slotted rotors. and the problem is the steerning wheel wasn't just shaking, i could hear a very deep braking sound, like a DEEP scraching sound.....

 

bad pads...

 

yeah...never ever replace rotors without replacing pads. You were doomed from day 1.

 

Dare we ask what you consider high speed braking? Does that include slaming on the brakes at 110MPH? What speeds are we talking about here?

 

It's the rotors again... same problem here. On my second set and working on my third. Glad I'm still under warrenty. Crappy OEM rotors. I'll probably get one more set before I'm out of warrenty then I'll get aftermarket ones.

 

If you replaced the rotors vs. turning them, you over torqued the lug nuts, which caused the rotors to warp FAST.

Use a torque wrench next time.

 

like from 80mph to 60mph....it's shaking really bad....just like the problem when you have warped rotors

now i know, i should re-tighten them with torque wrench

 

appx how many Lbs??

 

For lug nuts 72-87 ft-lbs

 

the dealer replaced my front rotors without replacing the pads before (eventhough i asked them to replace the pads) and after 3 months the rotors were warped again... this is when i found out they never replaced the pads... they put new rotors AND pads on for free after that

 

I always do 80lbs

 

stock rotors on the 5th gen max suck in general - your rotors are warped again - i've warped my rotors about 3 times in one yr- my cuz who is a mechanic resurfaced the rotors those 3 times - changed pads just to be sure and the same thing keeps happening - this spring im either gettin slotted or cross drilled rotors so they dont overheat like the stock rotors do - good luck
