Rotor Warping on 2004 Accord EX Coupe???

[theeedude]

I guessed it was the brake pads before reading this thread. They have a little piece of metal that starts making noise when they wear down enough. Don't let it go on too long or it will etch a groove in your rotor.
If you want to avoid warping, one method is after you brake hard or for extended period, like coming to a stop from high speed, while stopped, put the car in neutral and release the brake if possible, so that the rotor can cool uniformly instead of the part where the brake pad is touching cooling faster than the rest of rotor and causing warping.

For those of you warping your brakes:

Are you just unlucky with the build quality of your hub & wheel flange, or do the shops you continually go to always manage to mis-torque your wheel lugs?

The shop that I've used in the past has always used a torque wrench for final tightening and they list the correct torque (100 ft-pounds) on the invoice. I've come to the conclusion that Dodge vehicles tend to warp rotors no matter what (which is what I currently drive and was my previous vehicle also).

Read about the brake warping MYTH, from one of the top brake manufacturers:

It's either incorrectly torqued lugs (which you confirmed it's not), or hubs/flanges that have not been manufactured flat.

Short of that, it's mistaking brake pad deposits and hotspotting for warped rotors.

Oh, I wouldn't doubt for a second that it's the technicans overtorquing the lugnuts causing the issue. We were going to take my wife's Durango to Florida a few years ago. I noticed that 4 of the 5 lugnuts on the driver's side were loose to the point of almost falling off. I tightened them with the lugwrench but had no way to check torque. Within 400 miles, the rotors were pulsating the brakes. By the time I returned, they were so bad that it was literally bounching the Durango. Of course, with only 5,000 on the vehicle, Dodge replaced them (especially after I bitched about 4 of the 5 nuts almost falling off! :Q)

Edit: After reading your link above (excellent by the way), I now know that really didn't know jack squat about why rotors pulse. Thanks for the link.

Hey, i have the exact same car as you - 2004 Accord Coupe V6EX. I had the same issue about 6 months ago, noticed the car would vibrate when braking at high speeds. It gradually got worse and I had the brakes inspected when getting the tires rotated. Turns out my passenger front rotor had warped. I just replaced the front rotors a few weeks ago. My dad knows someone who resells brembo rotors so he got me those. So far they've worked great.

We have an 04 Accord LX V6 sedan. The rear brakes were 0% at 30K and the fronts were still OK. The wear indicator was making a high pitched squeal and it looked like it was about 10 miles away from metal to metal. It seemed a bit odd that the pad wear was not even for pads on the same wheel.

The dealer wanted $200 to install new pads with no rotor work.

I replaced the pads with original Honda pads because of possible warranty issues. Any idea if they have improved the replacement pads?
