Brake Help
 

Someone Please HELP!!! have problems with my 2006 300 awd limited warping the rotors . Does anyone know what rotor/ pad combination that works? Stock set warped, tried aftermarket set by Powerstop with holes and slots they only lasted a week .

if you are warping the drilled and slotted ones you may have an issue with the rear brakes not working, or you may have a caliper hanging up. I use one of those infra red thermometers to measure the temp of my rotors to see whats happening. If a caliper is hanging up and causing drag it will over heat a rotor and that rotor will be hotter than the other. if the rear brakes are not working properly the fronts will be doing all the stopping and also cause over heating. My car warps stock rotors within 3 months. But the crossed drilled/slotted ones go about a year.

Ahhhh i will haft to disagree with that Brake rotor warp is correct and can be measured by a disk brake caliper i needed. They warp like any other metal when u heat it up and cool it off rapidly. Simply clean off brake pads mmm no. I take u u have never cut a set of rotors in your life have you? Visit a place like O Reilly auto parts where they cut rotors for customers. There u can witness first hand when a set of rotors are warped or Out of round is the technical name of it. U will see the up to 10thousands of an inch on each side a rotor will need to be cut to make it flat again. SO build up on pads mmm possible myth of rotors not warping IM gonna call BS on that one. Or better yet let Myth busters have a crack at it see what they say.

Humm ok what ever u say buddy. As i said visit any ship that does brake work see if they will let an ignorant person like yourself to see the "unicorn" warped rotors when on a $6000.00 machine used to cut rotors true then come back on here and apologize to any one u may have steered in the wrong direction and name calling. MY knowledge seams poor based off the 18 years I have been doing this? I do assume I have vast amount more then yourself in brakes then yourself because you are basing your knowledge off of a web site and not actual hands on experence ??? Yeah I will take your website with more credit then any of the 250000 mechanics out there I would guess.

Back to the basics that appear to be overlooked.
TORQUE THE LUG NUTS WITH A TORQUE WRENCH
Air guns/just tighten them up real good is the Single Most Common Cause of Warped Rotors
Let's help Grego 1969 out here folks....

Chrysler Tech is correct all you need is a Dial indicator to see rotors are warped. I guess I failed to mention that I am ASE certified is suspension/steering and brakes and have been since 1982. Not only will Machined rotors stop smoother, they will stop you in a shorter distance also, as the pad is staying in full contact with the rotor!

Chrysler Tech...you obviously have little confidence in yourself if you cannot deal with other peoples opinions (facts) and have to resort to removing my posts. Brake Warpage IS a myth...in most cases. Google it.

U believe everything u read on the internet? IM not the one with the no confidence Iv done my schooling and my back ground speaks for itself. "Brake Warpage IS a myth...in most cases" Now we are getting some where The in most cases is what needs to be underlined here. U yourself this fake issue but I can rest assured with all the 1000s of rotors i have cut over the 18 years working on cars i can with the utmost confidence say they were infact warped. This is what real warped rotors looks like on a brake lath after watching this u tell me they there is not high and low spots on this rotor.

Nice video, however I am still not convinced that 100% of warped rotors are actually really warped. How am I able to burnish my brakes to remove the "warp"?. The only thing I can think of is that you may need to resurface some cheap Chinese disks, but good rotors don't warp. In looking at the video, it is obvious by the rust that they were not good rotors. Mine are painted, rust free, on the none contact surfaces.
Anyway, this is like talking religion or politics, I will never convince you, and you will never convince me. I do ask you one thing...if you are able to post a video supporting your claim, please allow me at least post a couple of links to support my claim. Thank you.

even seeing with your own eyes U dont see a warped rotor in the video? this is what just about any tech will see when its put on a brake lath and the bits are placed on the rotors.

And no u can pass it off for cheep rotors because I worked at a dealer for 15 years and they are factory parts and even the ones at any brake store are the same.

U pass off rust as being cheap rotors? All rotors will rust up at the bub point even if painted they will. Worse in northern areas with salt and sand and coastal areas with sail water near by. U can post links be u must also be objective post proof of your findings and facts. If u want to prove it to yourself Get a brake mic measure in 3 locations on your rotors see what the difference is in thickness is. Also what are u basing when you think the pads have hot spots? what does the brake pedal and steering wheel do?

Personally, I think much of what passes for "warped" rotors is actually corrosion. That video Tech posted makes me more sure of it. One of the things I learned in chemistry class many years ago was that corrosion actually takes place more rapidly in an area not exposed to air if it is connected to a portion of metal that is exposed to air. You get rust UNDER the paint around a chip in the paint on a metal fender. It has to do with electolysis. Likewise, I believe that if a vehicle is parked for a period of time, the rotors always develop some rusting, but the metal UNDER the brake pads may be rusting faster that the part exposed to air. Tech's video shows a low spot almost exactly the size of a brake pad. A couple of normal stops will wipe off all the surface rust, but the disc will be uneven.
Those other blogs talk about warpage caused by excessive heat, but I have experienced warpage on various vehicles and can assure you, the way I drive, excessive heat had nothing to do with it. Insufficient driving (long periods of being parked) seems much more likely to be the cause.

I see you point but U cant tell me that the amount of brake jobs I have done in the past was from cars that have been sitting for long amounts of time. Not around Atlanta. Warped is kinda odd word more like out of round is better term. And I have also seen it several rotors where there are more then one low spot. Some have 4 thousands of an inch and some haft to take off up to 20 thousands of an inch to get then true again.

Yes, I do see the "warped" rotor, however my point is that not all rotors that are cut, actually need to be. In my opinion, in my experience, and from what I read, most times the juddering people experience when applying the brakes, is simple a build up of pad material.

Anyway, I will apologize here, and now, for suggesting you were inexperienced in one of my posts you deleted. I do thank you for leaving my links to the rotor warp myth. Just like religion and politics, we will never agree on this warp issue. I am done with this. Thank you and enjoy your day.:)

The point of an argument or debate is to be able to see both sides which now u have. U at first came on preaching all about no such thing as warped rotors. I do change just brake pads on cars I do not always cut rotor or replace the rotors. The first thing u had said was I was a crook and over charging people for something u though was not true. Based off your personal experiences with how ever many cars u own. I on the other hand have done this cutting of warped rotors on many many different cars all walks of life all brands of cars and all different road conditions. Your own car this is all that u might need to do which I can infact see that is your issue. U must also condone that your car is not the only one out there and all are different how they drive who drives them and how they are driven. Rust on rotors is also a thing the part that the pads sit on will rust up over time if not used correct. But will not be the only cause for warped rotors. Science fact what happens to hot metal when cooled off vary quickly?

I agree that rapid heating and cooling is likely a source of warped rotors. I have seen a video of a Lincoln LS V-8 running up to high speed and then braking rapidly down to a stop. The video was shot in twilight and you could see the rotors turning red hot. You see that all the time on race cars. I gotta believe that sort of driving will result in warpage. It's just that in my case, I never drive like that. Now that I'm retired, I probably don't drive 5000 miles a year yet I still have gotten warped rotors, and so has my wife, and I doubt her rotors have ever gotten hot enough to boil water.
Given the humidity in Atlanta, I would bet that corrosion is a problem there, like it is in many places. Remember, rotors are just basically bare cast iron. They'll rust if you look sideways at 'em.

As you guys pound your chests, you do realize that the OP was 04/2013 ant the guy has never been back on the site.........

oh yeah quite aware
