Just wondering about this. I just slapped another set of pads on the rears, and I didn't measure but I noticed a pretty good lip on the edge of the rotors. I'm gonna measure when I can get my hands on a mic, but I was wondering how far you guys have driven on yours. I have 157K miles. (I got the car at 61K, though.) No cracking or anything visible on the rotors. And they're generally cool enough for me to touch only a few minutes after I stop driving, so not much heat generated on those, right? I know, I know, I'm a lazy son of a biscotti for not just going ahead and replacing them after all these miles and all this time, but tell me, how long have you driven on your original rotors?

 

i changed all my rotors at about 55k ..
two were warped slightly ..

i got dba slotted rotors for about the same price as new oem rotors ..

 

Interested...

 

Mileage isn't really an accurate way to measure rotor life since everybody drives differently. Your best bet is to just measure them and make sure they fall within specs. I would say if they have 100K on them you may just want to go ahead and get new ones.

I think my rears have around 58K on them (resurfaced at 39K) and they still appear to be fine. The rears don't have near as much stress put on them unless the traction control is kicking in a lot.

 

^valid arguement...

 

I usually replace my rotors whenever I do a brake job.

 

Where and how much?

 

Min have 68k and are original and uncut. I measured them recently and still in spec, but I tend to replace rotors and pads at the same time...so I might do that. I think I can get another 10k out of them.


I did my fronts around 45k. Rotors were still in spec so I saved them. I'll go get them recut so next time I do front pads, I'll swap the original cut front rotors back on.

 

I have around 113k on my 03.5 sedan and I have just turned my rear rotors for the 2nd time. Shop said there is plenty of metal left.

I definitely do not agree with swapping rotors out when pads are due. Certainly does not hurt, but IMO that is way overkill. If the rotors are fine, why replace them? I can understand turning rotors maybe at pad replacement .. although to me they should just be checked then and not necessarily turned .. but I don't get replacing rotors "just because".

YMMV, I guess.

 

Agreed. Unless you just have the extra cash to blow or you're just one of those guys who likes to replace everything no matter what, you really should only replace the rotors if they're warped or out of spec. You also only really need to have them turned if there are noticeable grooves cut in them.

My fronts were new at 39K and the rears were resurfaced. Originally I had planned on resurfacing the fronts and replacing the rears, but they look fine all around. I'm just going to give them a light sand to remove the glaze from the previous pads so the the new pads bed correctly.

 

63k and if i touch the brakes at all above 55mph, the whole car shakes. THey are quite bad and need to be replaced, but I don't feel like fixing them.... lol

 

Take off the rotors and cut them if they are in are in spec. Turning is cheap...about $10 a rotor here. Might allow you to go a little longer without needing new brakes and get rid of the shake

 

They were already done once at around 33k. How many time scan you turn them? All the rotors are original.

 

Until they are below the OEM spec in the service manual. There is no other limit.


One thing to not is that the rear pads usually wear out before the fronts on the 05/06 (and maybe 03/04) sedans. This is what I noticed on my car and it was confirmed by the dealer. So, there is probably more bias towards the rear which would result in more rotor wear in the rear.

 

I have 24K on my 09 and my rotors warped at 20K. But there is still mad pad left. I typically don't like to cut rotors because the thinner they are, the quicker/easier they warp since they don't dissipate the heat as well as a thicker rotor. Buuuuuut, I know these Sport front rotors are gonna be super expensive, and I can turn my own rotors for free. So turning them is looking pretty tempting right now. Lol. Nissan rotors for some reason seem to warp quick. And I'm not overly hard on my brakes. But I have always replaced my own rotors. I recommend new ones to customers along with the option of cutting!
