I stepped on the brake pedal at 80mph and felt the wobbling vibration. I changed OEM front brakes once since I brought this car new. What do you folks think?

 

Probably warped rotors.

 

get ur rotors surfaced?

 

do we need to resurface rotors every times we install in brake pads?

 

How long ago did you change the rotors??
You can find cheap rotors on ebay..

it is the same original rotors since i brought the car new. i have less than 41k on the car. brake pads would checked and the pads still have 50% left of use. you think it is the rotor?

 

Depends on how you drive. My girlfriend waits til the last monent to press the brakes. Which in turns puts more pressure and friction on the rotors which warps them in time.

 

not unless they are warpped...if u change ur pads on time u can save ur rotors from warping...

but if ur rotors are warpped u should change them w/new pads, b/c if u dont, u'll just screw up the new pads, b/c the pads will wear unevenly accordin to the warpped rotors..

 

what is warpped pads and warpped rotors?

 

it means there uneven not smooth

 

its warped rotors, no doubt. over time as they get hot, cold, hot, cold, hot, cold, they get a little bit uneven and as the pads come across a higher section, it grabs harder, and when it comes across a lower section of the rotor it grabs less. Now, when you figure this with the rotor spinning at 80mph, that will feel like a vibration.

 

exactly, i got the same thing on my 2k2 rotors. they warp very easily. nissan made poor quality rotors. but i never heard of this problem on 4th gen rotors.

 

it does not make sense to resurface rotors right? i should purchase new rotors from local stores correct? i am not an aggressive driver.

 

you should always check your rotors
