Do the stock rotors warp easily? After a while they started to pulsate (car makes slight repeated jumps, steering wheel shakes) and when I pulled the wheels off I found out I had worn the pads down to nothing. I replaced the pads and turned the rotors on a brake lathe I had at work and adjusted the rear drums and it was fine for a while, but now the brakes pulsate again when I brake hard on them not even seven months later. What's the deal with that? Do the NX2000 brakes have that kind of problem?

hmmm.......

personally, i don't like machining the rotors, if they're low and out of specs, they're gone, and same goes for the drums, and if you plan on upgrading to nx big brakes, get set to remove the dust shield, it's a very good upgrade though.........

I mic'ed the rotors before I machined them and they were still in spec so I turned them. I'm not sure if I really trust the Hunter pos brake lathe I machined them on though, so that could contribute to my pulsation problem.

While we are on the subject of brakes, I haven't wanted to make the jump to low profile tires. Will NX2000 brakes fit behind 14" alloys?

I think it's just the size, our stock rotors are way too small so they tend to get warped and pulsate after a while. I replaced mine about a year ago and i'm starting to feel a little pulsation when i brake hard. The NX2000 brake upgrade seems to be the only solution for warped rotors...

yeah, the stock rotors are prone to warping. the Sentra was pretty much made for the granny drivin grocery getter that drives below the speed limit apparently. the AD22Vf upgrade is probably the best way to go. I've driven 10K miles since I've owned my car and I've already gone through 2 sets of rotors. next time I need new brakes, I'm doin the swap.

If you've gone through 2 sets of rotors in only 10k miles something is seriously wrong with your brakes. Unless your running Hawk Blues you should be getting about 50k on OEM pads.


As far as the rotors warping... a number of factors are probably involved there. The rotors are thinner... so if rotors really do warp (this is debateable) then it stands to reason that this is more likely.

You may also be riding your brakes or be really hard on them... when your at a light, do you hold down your brakes the whole time (as you'd have to with an Auto)? If the pads are hot... as they cool, they leave pad deposits on the surface of the rotor causing high spots... it also physically changes the structure of the metal at those spots making it hard to permantly resurface them. This can also happen when your pads/rotors are hot and you drive through a puddle of water... the sudden cooling of the rotors/pads can cause excess pad material to be laid down in one spot.

High spots on rotors are more noticeable on smaller brake systems because of their over all size. If you go with an AD22VF upgrade you can still have problems, but they probably won't be as noticeable.

well, the rotors were already warped when I had the car (didn't notice it b/c I was a new driver). As I drove it, I started to notice. So a few weeks after I got the car I talked Nissan into replacing them for free. just recently, I had to replace them again (brakes were squeeking and I needed new pads) so
I brought it in and they told me I needed new rotors, so now this is the 3rd set since I owned my car (10k mi). They did mention high spots, but I didn't know what that meant. anyway, I do have an auto (for now), but usually at a light, I throw the car in Neutral and let off the brakes.

BTW, I don't ride my brakes (I hate when people do, especially being in FL). But I'm usually hard on them because I like to drive fast.
