just need some help why do my brakes pulsate i change the pads and rotors look good . does any know or have had this issue

 

Probably you need to balance your wheels ... I check that first

 

U can't see warped rotors. Mine are nice and smooth looking but when I brake it pulsates so much it feels dangerous.I got my 6th Gen big brake kit waiting for a nice day to put it on

 

This is true if it vibrates at all times not just braking

 

could be that they are so new they have not been broken in yet?

idk, but with new pads and rotors, that should solve it I would think..

maybe you have some strut or other issue that causes the vibration when braking?

 

rotors might be warped. Did you install new pads on the old rotors without having them turned?

 

try bleeding your brake lines...


could be that you got a wee bit o air trapped in there.

 

He said his rotors look good, means he didn't put new rotors

 

OK thanks. I had not replaced rotors but seems reasonable and I guess that is next step. How do rotors warp. Are performance rotors really worth it

 

brembo blanks are worth it, most others are not, and drilled rotors are a great way to send money directly into a furnace

our rotors tend to warp by picking up brake dust deposits into the rotor, seems to be a crappy Nissan OEM rotor problem, my brembo blanks have been going strong for a long time

 

I have a 2002 SE. Every 10,000 to 15,000 miles the front brakes start pulsating. Then it gets worse as more miles are logged. I agree that the probable cause is uneven buildup of pad material on the rotors, but I don't know why it does this on the Maxima.

The problem is easily resolved by having the rotors turned. This last time I installed new Brembo rotors and Hawk street pads hoping that this combo would help. It did not. After 15,000 miles, the pulsation has returned.

Any suggestions? Thanks in advance.

 

Upgrade to the 6th gen Big Brake KIT..... I'm well over 30,000.... Still brakes like a champ and smooth

 

I have similar experience with my car (2000 SE).

I have installed Brembo blank rotors and Raybestos Quiet Stops pads (at 35K miles Front, and 50K miles Rear) and the pulsation went away - for a short while. It came back after 15-20k miles.

I have found that washing the car (or just watering the wheels) greatly reduces the pulsation - for a few days. I am now experimenting with "Squeal Medic" spray (you can buy it at O'Reillys). It seems to help a lot more. I just started, so I can't report on how durable this fix is.

From what I have read, the pulsation is more often caused by deposits on the rotor than actual warping of the rotor. Also, the angle at which the pad is pressed against the rotor is a factor. So, I am thinking of disassembling, cleaning, and lubricating/servicing the calipers and pads next.

 

Rotors dont wear perfectly even, take the rotors to your auto parts store and have them turn them. It is basic maintenance. No pad material builds up lol come on. Try not to slam on your brakes every time and it wont happen so often

 

Brakes are undersized for the power and weight of the 5th Gen Maxima. Bigger brakes will solve the longevity and performance of the brakes.

 

engine is undersized too.....better go boost

 

Correction ment to say 5.5th gen. 5th Gen is undersized

 

I had heavy pulsating which kept getting worse. Changed rotors. But thought everything is attached to the axle. If the axle is warped or bent, the hub is oscillating. If the hub is oscillating, then the rotor is also. I changed my long axle on the passenger side. Problem solved.
