What Causes My Car to Shake When I Brake and Accelerate?
There are several reasons why your car might be shaking when you brake or accelerate. Here are some of the most common causes:
Worn-Out or Loose Belts
Belts are an essential part of a car’s engine, responsible for powering various components such as the alternator, water pump, and power steering pump. When belts become worn out or loose, they can cause vibrations that are transmitted to the rest of the vehicle, leading to shaking when braking or accelerating.
Signs of Worn-Out or Loose Belts:
- Visible signs of wear and tear on the belts
- Unusual noises such as squealing or grinding
- Vibrations or shaking when the engine is running
Bad Wheel Bearings
Wheel bearings are responsible for supporting the weight of the vehicle and allowing the wheels to rotate smoothly. When they become damaged or worn out, they can cause vibrations that are felt throughout the vehicle, leading to shaking when braking or accelerating.
Signs of Bad Wheel Bearings:
- Grinding or screeching noises when the wheels are rotating
- Vibrations or shaking when the vehicle is in motion
- Play or looseness in the wheel bearings
Unbalanced or Out-of-Round Tires
Tires that are unbalanced or out-of-round can cause vibrations that are transmitted to the rest of the vehicle, leading to shaking when braking or accelerating. This is especially common when driving at high speeds or when the vehicle is loaded with heavy cargo.
Signs of Unbalanced or Out-of-Round Tires:
- Vibrations or shaking when the vehicle is in motion
- Uneven tire wear
- Difficulty steering or handling
Bad Brake Pads or Rotors
Brake pads and rotors are essential components of a car’s braking system. When they become damaged or worn out, they can cause vibrations that are felt throughout the vehicle, leading to shaking when braking or accelerating.
Signs of Bad Brake Pads or Rotors:
- Squealing or grinding noises when the brakes are applied
- Vibrations or shaking when the brakes are applied
- Unusual brake pedal feel or travel
