Please help...

This is the 2nd set i have had problems with. I get a slight judder and a grinding noise combined with the high pitch squeel as if the pads are worn.

I am using the AXXIS pads and they are 90% new. Rotors are 3-4 mos old.

Please take a look at my pics and if anyone can tell me what the problem is. Some lines are forming on the rotor and when u feel it with a figer, it feels like indents in the rotor.

Maybe there are small rocks stuck between the pad and the rotor creating the grinding noise and doudging the rotor.

 

Maybe sticking calipers.

 

not sure?

 

What yr do you have, I have had mine on for about a month and no complaints.......so far.

 

The holes aren't dimpled and it looks like the gouges are forming at the edge of the holes. My guess, the hole edges are creating the gouge in the pad and the pad now has uneven surface gouges back the rotor.

So your saying that the rotor is defective and in turn made the pads defective as well?

 

That's par-for-the-course with x-drilled rotors on the street. That's why everyone recommends against using them for a daily driver. Trailing edge wear is very common and what usually leads to them cracking, in addition to warping.

As for PAD wear, now you know why they call 'em cheese graters.

 

Hmm...yeah it's possible all these problems are coming from the holes because they aren't chamfered around the edges. I have x-drilled, and slotted and have not had any problems at all. I've had them for about 25K, no cracking, no warping. So I think the problem lies with the holes not being chamfered around the edges.

I would contact Stillen and ask about the rotors. Ask them if the holes they put in them are chamfered around the edges or not. If they say yes, then you have defective rotors. Then you take it from there... If they say no, then I would look for another brand of rotors and stay away from Stillen.

 

wow ur rotors have alot more holes than mine do??? Mine are also stillen but i havent had any problems with mine.

The rotor i have is a gen2 rotor of the x-d rotor that came out NOV 2002.

Just got off the phone with stillen and they might be replacing rotors.

 

sorry to hear the misfortune Igor i know it can be very irratating. i have the stillen X-drilled rotors no probs what so ever.

 

Yeah I don't know what they were thinking with those gen2 rotors. They have so many freaking holes and they aren't even chamfered,

 

I dont have Stillen's but do have x-drilled, slotted brembo blanks from race concepts.. no problem so far.

 

XXact same rotors here with Stillen Metal pads all around. Going on 20K, not a single problem yet. Nissan OEM's started to go bad at 23K.

 

I just noticed something odd in pic1: the holes go from left to right on the side closer to the caliper and on the other side of the rim spoke they go from right to left....I have never seen that before on x-drld rotors....why is that?

I agree with the others.....a lot more holes and they are not chamfered....the gen2s may be worthless.

 

Does any1 run these rotors with AXXIS pads?

Maybe the pads are what screw up the rotors?

 

4th gen here with the Stillen setup. Been running them for 15K miles now. Pads still look like new, brakes are smooth as slik too. Looks like Stillen changed the design a bit, perhaps a few to many x-drillings.

Keep on Stillens back until you get your problem solved.

 

thats the rotor i had the 1st time!

I dont like the new 1's. I want my smooth braking back!!!

 

Hey I remember a member here possibly putting those Stillen Gen2's on his car. I think his name was "serin". Do a search and check with him. He may be able to help you out. He was wondering why there were so many damn holes and he put up a thread before he put them on....if he did put them on, not sure.

 

I guess ill wait till around 12EST till stillen opens and call my guy back and ask him if i can have GEN1's back.

 

hey njmaxseltd, is that pic when ur rotors were brand new or is that what they look like after 15k, cuz they are pristine! Mine are all rusted and stuff around the edges....




-Steve

 

Thats what they look like before the pad has even touched them haha.

That goldish color goes away after they brake in

 

yeah thats what i thought cuz thats how mine looked once too lol.... i wish they stayed nice and purty haha.

Stillen will not warrenty my rotor! WTF! They said 30 days for defects.

THIS IS BS!

Can anyone please help me or give me advice? he guy i spoke to is Bill who is a manager and he said he wont do a thing.

 

I am quoting myself......anyone care to comment on my observation regarding the change in direction of the holes?

 

What do you mean by the direction of the holes? They look to be in the same direction to me. Are you referring to the direction in which they were drilled? Or the angle they were drilled?

 

The brake set up in these cars sucks!!! I picked up a 2000 in 2000. Brand new. I was pretty impressed with how hard it stopped. Really short distances with no fade. I used to tell friends with big rotor cars like C5's and Cobras Stangs how good my car stopped. Then around 9000 miles they warped. Not one ot two rotors, all of them. I brought it to a local shop that I used to work at and they put new pads, shims and resurfaced the rotors. It last one week befor ethey were warped again. When I rotor is resurfaced it makes it thinner which in turn makes the rotor harder to dissipate heat. So what do I do now?? I called Nissan and they said I needed to leave the car and it probably will not be covered!!!???under 10k!!!! I priced a new set of Nissan rotors and pads and it was out of hand. So I picked up 4 stillen rotors and Axxis pads. First of all they are noisy as hell. Sounds like grinding brakes everywhere. I put about 11k on these brakes and they are beat. Pads are thin as hell and guess what?? All 4 rotors are warped again!!! The problem is not in rotor design, but in overall brake design. The max is not a light car, it has power to go pretty fast. The small brake sdesign cannot handle the heat dissipation that is necessary to keep rotors from warpage. I heard the newer model(03) have large front rotors. That may help slightly, but I think it needs some beefy brakes and a more agressive shift for it to be worth it for me to get another one. Otherwise it is BMW time. Sept is my lease end date. Another thing. The traany popped. I brought it to the dealer. They told me they were NOT authorized to give rental cars. I went ballistic! I told that jerk that this is the first time I ever brought it in. I told him it needed brakes at 9k and since I had to leave it I spent 600 bucks on brakes myself. I told him that the max is suppose to be the flagship of Nissan. I told him that I leased the car from this dealer. I was yelling at this poor guy. Maybe it was all the gear, but i was raging out and about to get violent. This guy talks to the manger and call Enterprise to give me a car. I asked him how long and he tells me a day or so. He also said it wouldn't need a trans, just some adjustment. Yeah right. I was in the auto repair field for 10 years. I know when a tranny is beat. So needless to say it took 2 and a half weeks!!!!! They paid for the rental so who cares. They had to call a Nissan rep to get approval for the trans. They said it was very uncommon for these tranmissions to go like this. Sorry just had to vent a little.

 

Are you still on the stillen rotors? Did u get the problem fixed? Any1 tell u to use the stillen rotors with stock pads?

Any comments anyone?

 

Hmmm...no idea, weird. Maybe it was Stillen just changing a little something to see how it would work? I wonder if this 2nd gen rotor got much test time before it went into production.

 

I think you should try a few things before raising to panic level. First, go get the things re-surfaced. Maybe that will help. Second, you are driving around in the D.C. area no? SALT. SAND. That stuff can get trapped in between your pads and rotor. By the time you see it, it has already been ground away. That would cause squealing and could make the rotor minutely uneven. That is my .02 See if it helps. I have the Stillen rotors and pads and I try not to drive around at all during the winter. But when I do, like clock work, I get the brake squeal.
