Anyone have problems with rotors warping often on a 2001-2002 Honda Accord V6? I've had mine done about every 20K since it was new because the pulsing when braking gets unbearable. This car also seems to eat through pads fairly quickly. I am not an aggresive driver by any means and 90% of my driving is highway with little to no traffic. I asked my mechanic to use non-Honda pads, but he said the aftermarket pads wore faster. Any suggestions?
