Need advice...warped rotors ROUND 2 - Toyota Nation Forum : Toyota Car and Truck Forums

Eyekutr · 06-05-2009, 01:41 AM

Hi fellas
at around 20k miles, my rotors were warped and after some convincing my service adviser had them turned for me for free. We are at 41k miles, they are warped again. When turned initially, same pads were kept and lug nuts were hand torqued by myself. Now, looking at the pads, there is still 4-5mm of pad (we do mostly highway), and the rotors have normal coloring but wheel vibrates when brakes are applied......I guess my question is, what rotor should I buy to get rid of the vibration and avoid warping. Should the pads be swapped eventhough they have lots of life left?

If u go with bigger rotor, I doubt that current caliper and pad can be reused...

Eyekutr · 06-05-2009, 02:03 AM

No. not bigger, this is a 4cyl camry so no BBK conversion, just looking for ideas on what to do to remedy the recurring issue? perhaps using old pads on turmed rotors was a no no, I dunno...I was perhaps also looking for a reputible brand to swap for oem rotors which may be too crappy?? I guess easiest remedy is to return the rotors if thickness is OK and Ill be fine for another year or so..

maybe this???

Yes those drilled pattern will minimize the temp difference and thus eliminate the warping issue ... Theoritically ahem ... Just wait for more input.

Well rotors and pad ruin each other. You should have went with new pads because the first warped rotors wore the bad unevenly and when you turned the rotors and used the same uneven pads, it ruined the rotors again.

A lot of people have had problems with their breaks on the Gen6 so maybe a different brand? Not AutoZone brand or anything like that.

im having the same situation too, i machined my rotors twice already and i have more mileage than you lol, im pushing 63k give or take...

im waiting for time and money and when i have enough, im going to buy my rotors and perhaps pads as well from GENNE, he has some BREMBO rotors for our GEN6, if you have any questions about them, ask GENE and PEACH (PAUL) bc Paul has them on or so GENE told me lol

you need to have your calipers rebuilt, they are sticking. you can DYI. about 300.00 if you pay a mechanic.

No calipers are fine, if they were sticking the pads would be down .....right ??

ebumdude · 06-05-2009, 11:05 AM

i just had my rotors turned too @ 29k miles.

Eyekutr · 06-05-2009, 05:55 PM

Okay, now your will hate this. We are all trying to help and I imagine your getting frustrated as I would feel to.

First what sort of driving are you doing? You slam dunking the brakes? Second go easy on the brakes to start. Wear them in for at least 900km about 500 miles. An I am not saying hit the back of a truck to take it easy on them. But they really need to be broken in. If your taking those new brakes out and really testing them its a road to ruin. An turned brakes are a doomed situation on these brakes. I went out and felt the brakes on this car. It is a 2010 so maybe a bit diff. But they don't look happy for turning. Next I agree with above, turn them and change the pads. They have meat yes, but once you thin them down your limited. Thinner brakes more chance to warp.

Now another big one. have all your suspension and linkage checked. It might not be the brakes at all. Well brakes a bit but if anything is loose it amplifies it. Also are you the only one driving this car? On my German car I was getting warped rotors with the style of driving she was doing (wife). These are street cars not race cars.

You can go to drilled (brakes) diff pads and all, and you might need them, but if anything is off they will not make you happy.

If you are a very hard driver you might want to change up. But I would start with the basics first.

So again start with what am I doing wrong? Then work back.

So I would hope that would be called real. Oh and good luck

Happy driving.

EDIT: OH and I have not looked at what is in the composition of these pads yet. But if you do not wear them in, and they have ceramic in them, or carbon, and lay the composition on the discs right they will feel warped. Actually it will warp them. Sorry new to this car but just putting down what I know. All brake pads are a composition. It is important to lay a layer of the pad on the disk. Yes it looks worn off but it embeds. Maybe a better way of saying.

Hi judge
you have some good advice. For the record, I bought the camry for my dad, who is 64 and drives mostly highway. He tends to drive the car hard with panicky braking....he must be riding the brakes too hard....

Ah, okay we are heading some were. Sad to say I doubt a 64 year old is jumping on the brakes ( I mean like a kid). But yes tailgating and jerky can have the same effect But! Check all the steering stuff links and all, is this car new? or old? maybe it is not straight? Get garage to do a cross corner tape measure of it. An does he let his left foot drag on the brake? you know just rest on it? Waiting to jump on it? If he is doing that he will keep them hot and when he does his panicky stuff, it adds to it.
You might want to wear in the brakes for him and try to have him keep his left foot on the pad not near the brake?

Now this is all guessing ok. From what you are saying.

So get all checked including if the car is straight. Then if all is good you try and start driving that car, you can cheat a bit (with new brakes, pads and all). When you start driving it with new brakes as you leave the driveway touch the brakes a bit and keep doing it a bit, but do it soft, and not to often. Don't want to get them to hot but just touching,not often and not at high speed. Go around 60 miles doing that. But never much and never hard. That will work well. Sorta just kissing the pads to the disk. You will wear material into them. An never let him leave the parking brake on when leaving overnight. Not good to do.

These are heavy cars and the brakes are very well designed for standard driving.

An that is the best info I can give.

Happy driving

EDIT: Yes I see it is not new, what I meant by that do you know if it is not a well, you know. Lets just say did you do a carfax? Or buy from family, sorry just wanted to make it clear.

Hey judge
I bought it brand new in 07, at 20k miles, rotors were warped and dealer turned them and kept original pads. No accidents, car drives perfect and straight, suspension is straight and tight. Thanks for the info

Okay. An no insult meant. I would still try the stock brakes again but wear them in for him.

EDIT: See, what can happen if someone is hard on new brakes is a thing called skipping. It is when the pad material is laid down uneven on the disks. This feels like warped brakes and will actually lead to such. It is the reason you want to wear them in easy. This is the first Toyota I have owned and am learning it still. But brakes these day tend to be very close.
