What Causes Car To Shake When Braking

Over time, brake pads accumulate oil, dirt, or other materials. When this happens, the substances can cause vibrations, particularly when you press the brake pads. Also, over time the rotors get thinner, making them susceptible to damage. During braking, excessive heat is generated and can cause the rotors to warp.

How do I stop my car shaking when I brake?

An auto mechanic may be able to adjust, shim or resurface the rotors to compensate for the unevenness, but replacing them is a surer bet, and a relatively easy DIY job for those comfortable under the hood, too. And, some mechanics recommend that you always replace rotors and brake pads at the same time.

Is it bad if my car shakes when I brake?

If you feel the shaking or vibration in your steering wheel and your brake pedal, it could be your rotors. The rotors get pressed by the brake pad to help slow your vehicle down, and if the rotors are out of balance, this could be causing the vibrating tremors that you feel in the pedal and steering wheel.

What causes a car to shake when braking at high speed?

Brake rotors become warped over time from the heat generated from the friction produced when braking. When rotors are unevenly worn, the brake pads only come into contact with the rotors in certain areas producing a vibration, usually when braking at highway speeds.

Why does my steering wheel shake when I brake at high speeds?

Unevenly-worn or warped brake discs (rotors) can cause the steering wheel to shake when brakes are applied. In most cases this issue is caused by warped or unevenly-worn front brake rotors (discs), although there could be other reasons. Warped or rusted rear drums can also cause brake pedal pulsation.

Why does my car shake when braking downhill?

When you hit the brakes while traveling downhill, the brake rotors normally heat up. This heat can cause the metal to expand which causes the warpage shaking through the car as your speed reduces.

Can a brake rotor be out of balance?

An imbalance is when one side of a rotor is heavier than the other side. Imbalanced brake rotors can cause a vibrating feeling to the driver and passengers when a vehicle is in motion. Also, imbalanced brake rotors lead to accelerated bearing wear.

How much does it cost to balance rotors?

Your rotors can be turned (rotated), machines and still be within factory guidelines, but this usually leaves them thin whereby leaving them to warp or vibrate. The cost for turning a rotor runs anywhere from $15 to $25 per rotor.

How much does it cost to replace brake rotors?

What is this? When it comes to replacing brake rotors, regular blank and smooth rotors cost between $40 to $90 a piece, while the labor cost is between $100 and $150 per axle. In total, replacing both brakes and rotors on one axle will cost between $250 and $430.

Can a bad CV joint cause vibration when braking?

A damaged axle can cause suspension vibration, oftentimes fairly severe shaking. Damaged CV joints can produce suspension vibration in your car, and will need to be replaced. In fact, if you drive for too long with faulty CV joints, you may need to replace your drive axles too, which will cost you significantly more.

How much does it cost to fix a warped rotor?

Like the brake pads, the brake discs can eventually wear out as well. If you want to replace your brake discs then it will cost you between $200 and $400 for the parts and about $150 for the labor. This means you are looking at around $400 to $500 total for a brake rotor replacement job.

How do you tell if your rotors are warped?

Signs Your Rotors Are Damaged If you notice your steering wheel or brake pedal wobble when you apply the brakes to slow down or stop, chances are your rotors are warped. If the warp isn’t too bad, you might not really notice the shaking. If the warp is serious, you’ll definitely feel the vibration.

Can out of balance tires cause vibration when braking?

The most common reason for a car to shake is related to tires. If the tires are out of balance then the steering wheel can shake. If your steering wheel shakes while you are braking then the problem could be caused by “out of round” brake rotors. This vibration can also be felt through your brake pedal.

Can wheel Alignment cause vibration when braking?

Consistent Shaking: Alignment issues will cause constant vehicle vibration, no matter whether you are braking, accelerating, or maintaining a consistent speed. Steering Wheel Pulling: You may also notice that your vehicle is “pulling” towards one side of the road or another rather than seamlessly steering straight.

Can a driveshaft cause vibration when braking?

The root causes of these are usually a wheel, rotor, or driveshaft. If a vibration gets substantially worse while braking, it’s probably an out-of-true brake rotor. But if you’ve ruled out wheels and tires, and you have a rear-wheel-drive car, the next likely source of vibration is the driveshaft.

What causes out of balance rotors?

Occasionally, cast rotors such as pump impellers or large sheaves have blow holes or sand traps which result from the casting process. While undetectable through normal visual inspection, blow holes may be present within the material and create a significant source of unbalance.

How often should rotors be replaced?

Ideally, you should have your brake pads replaced between every 10,000 and 20,000 miles, and your rotors replaced between 50,000 and 70,000 miles.

Does AutoZone do rotor machines?

Does AutoZone Replace or Rotate Rotors? Like an O’Reilly Auto Parts shop, AutoZone may offer to replace your brake rotors if they have a mechanic’s service in the back. Many auto parts stores are built-in with mechanic shops in larger cities, as the two work together.

How often should rotors be turned?

Typically you want to have your rotors turned every other brake change. This ensures that they remain free of debris and do not warp. Regular brake wear and hot spots can often cause your rotors to become warped and having them turned will ensure that they last as long as possible before having to be replaced.
