warped drums?

[ellenbetty]

I am getting a pulsing feed back on my 2007 Toyota Yaris brakes. Light when driving and heavy when pushing down on the pedals. The local Toyota dealer repair department says that the front brake disks are warped from driving too little, and the problem is not covered by warranty. The repair department says that the problem is not dangerous. Of course some of the problem could be a alignment problem. Given the shape of the parking lot over the past 1 1/2 years (lots of pot wholes and lots of sand to get into the brakes) is this a warranty problem? The idea of having to pay to have my disks turned at 11,400 miles to get rid of the bump does not appeal to me. Will this problem correct itself? Should I take the Toyota Yaris to a speed shop and get the brakes upgraded? Should I take the Toyota Yaris to a regular brake shop and have the problem fixed? Should I file a complaint with Toyota USA over the issue? Should I file a complaint with the US DOT over the problem?
