Why does my car vibrate when I brake at high speeds?

Why does my car vibrate when I brake at high speeds?

The vibration is generally caused by the brake rotors being warped. When you hit the brakes when traveling downhill, the brake rotors heat up as normal. This heat can cause the metal to expand, resulting in the warpage shaking through the car as your speed reduces.

Can alignment cause vibration when braking?

If done improperly, a bad wheel alignment can cause vibrations when braking as the tires aren’t inline with one another. This will cause the car to not only be unstable but also wear out unevenly. Additionally, new tires that aren’t balanced properly can also cause steering vibrations as well as uneven wearing.

What causes engine vibration at idle?

A worn out or faulty spark plug is a leading cause why your car engine vibrates or shakes uncontrollably. This can result in the engine to vibrate as the cylinders can misfire during idling or at running speeds. Installing new spark plugs is the best way to resolve such vibration related issues.

What causes idle to go up and down?

Erratic engine idle can be caused by various factors, but the most common and likely cause is a dirty or malfunctioning Mass Air Flow (MAF) sensor. This is a device found in fuel-injected cars and measures air flow so that the appropriate amount of fuel can be injected.

What does a spark plug misfire feel like?

You may also feel intermittent jerking, bucking, or stumbling from the engine. You’ll notice rough and/or slow acceleration. Vibration while the vehicle is running is common especially if the misfire is caused by a mechanical problem. The severity varies depending on the RPM and is often worse at idle.
