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, :eyebulge: 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?

Toyota is good at excuses when it comes to the yaris brakes. They told me that the hills I lived in caused premature warping of the rotors. Which by the way, warped 5 times by the time I got to 1 1/2 years.

I just picked up R1 drilled and slotted rotors and carbotech pads from microimage, which so far have lasted much longer than the OEM.

Another option is to remove the rotors yourself and most machine shops will turn them down for 20-25 dollars.

Landlady rules forbid do it yourself car repairs. Landlady likes to give fines for those who violate her rules.

Are you talking about the front or the rear. Your title says "Drums" and then you talk about "Disks" (aka rotors)? If your disks are warped then you will feel the vibration in the steering wheel. If the drums are warped then you should feel it in you butt more. Disks are more likely to warp unless you have driven with your E-brake on. Also they Disks and Drums can both be warped by over torque and uneven torque of the wheels

I've heard before that after a sudden stop you let the car slowly roll forward some (whenever possible).

Putting the parking brake on hard with the drums hot and expanded from recent hard braking will warp them as the drums cool and contract, with the brake shoes wedged out against two sides. The drums ovalize.

A car that's been left sitting outdoors undriven for a while will develop a rough patch of rust under the pads on the disks. That makes noise when you drive off, and makes the braking a bit rough till the disks get evenly polished again.
