We know our cars very well. We spend such a large amount of time in them daily that we profess a keen ability to know when something is wrong. One common issue that we see allot of is the feeling of a vibration from the vehicle when hitting the brakes. You will be traveling at a high rate of speed on the express way. As you come up to your exit you hit the brakes to begin slowing down and feel the steering wheel shake back and forth. You may also feel the entire car shake and shutter.
Because this is only happening when braking, there is a very good chance that the issue is with the disc rotors. The disc rotor is the round steel plate that the brake pads clamp down on to stop the car. The disc rotor, like the tire, turns at a high rate of speed when traveling. A new disc rotor is designed and machined to a perfect zero specification. If it ever warps or becomes out of round due to extreme temperature, a vibration will be felt when the pads clamp down. The more warped the disc rotor is, the more vibration will be felt when braking.
In most cases, the correct fix is to replace the warped disc rotors with new ones. I also suggest renewing the disc pads with the new rotors. Machine resurfacing the warped disc rotor can also help but is not recommended. The resurfacing process removes more metal from the disc rotor. In today’s times, disc rotors are less heavy, and less thick than rotors of the past.
