damn really? i havent ever hit the brakes at freeway speeds and i am pretty cautious about how i drive. but what can cause warped rotors and what are the signs, like any marks or something on the rotors that could help give that away?
How many miles on the car? Do you still have original brake pads?
With the Accords, the front brakes "warp" quite easily. Although, I'm under the impression that they rarely actually warp, I'll explain in a bit.
Brake rotor warping occurs when you heat up the brakes to a very high degree from hard use (sometimes abuse). Hard use is a situation where you are coming to a more or less sudden stop from highway speeds, ie. Slowing down from 80mph to 40mph in a sudden maneuver. The heat that is produced by the friction makes the rotor more malleable and therefore more prone to change shape slightly. This isn't always the case, in fact, i think this case is pretty rare. I think more often than not, the brake pad material melts onto the rotor and creates an uneven braking surface, therefore giving you the pulsation. In order to remove the deposit, you can take some sand paper and clean the rotors braking surface with it in a light, circular motion. And, there is no need to use a low grit sand paper. Use a finer grit sand paper because it is more gentle.
Occasionally, the deposit is small and will work itself out with the use of the brakes. However, if this problem has been happening for a while, you'll need to take action and use the sand paper procedure and if your rotor is actually warped, you may need to get it machined or replaced.
I hope this helps.
