You’re cruising along, enjoying the drive, not a care in the world. You apply the brakes… And are instantly met with a disconcerting vibration. If your car shakes, rumbles, vibrates, or shudders when you brake, it’s important to identify what is causing your car to shake and perform the necessary repairs. Here are the things to look for in order to diagnose why your car is shaking, as well as some tips on repairing your car.
What causes a car to shake when braking?
There are a few things that can cause your car to shake, one of the most common being worn-out tires. However, if your tires are in good condition and the car is still shaking, the next best guess is your brakes. Car brakes are made up of several parts, so you’ll have to pay attention to what your car is telling you in order to diagnose which parts are causing the shaking.
Your Rotors Are Out of Balance
Next time you’re driving your car, pay attention to where the vibration is coming from. If you notice it primarily in the steering wheel or the brake pedal, your rotors may be out of balance. (The rotors are the disc-like iron parts of your wheel that connect to the hub. When you hit the brakes, the brake pads and rotor are pressed together, creativing friction and slowing your speed.)
Your Brake Calipers Are Sticking
A shaking car can also be caused by brake calipers sticking. The calipers are what slow down your wheels when you brake. Think of them as a clamp opening and closing around the disc of your rotor. Insufficient fluid can cause a lapse in hydraulic pressure, which means the calipers can’t do their job of pressing on the brake pads.
Your Brake Pads are Worn Out
The last common explanation for a car shaking when it brakes is worn-out brake pads. Brake pads are designed to wear out over time, so you can expect to replace them every 40,000 or 50,000 miles. They will eventually wear down until only a quarter of the pad is left, and at that point many of them are designed to squeal or shriek to alert you to the fact that it’s time to replace them.
