Car Shakes When Braking: Possible Causes

A shaking car when braking is a common issue that can stem from several different problems, most of which are related to the vehicle's braking system. It's important to address this issue promptly as it can affect your car's stopping power and overall safety. Here's a breakdown of the most frequent culprits:

• Warped or Damaged Brake Rotors: This is the most common cause. Over time and with repeated use, brake rotors can warp due to heat and friction. This warping creates uneven surfaces on the rotor, causing the brake pads to vibrate when they come into contact. The vibration is felt as a shaking or pulsating sensation in the steering wheel (especially during light to medium braking) or even throughout the entire vehicle.

• Uneven Brake Pad Wear: If your brake pads are wearing unevenly, one side of the rotor will have more contact than the other. This imbalance can cause vibrations during braking.

• Sticking Brake Caliper: A sticking brake caliper can cause constant pressure on one or more brake pads against the rotor, even when the brake pedal isn't engaged. This can lead to overheating of the rotor and brake pad, resulting in warping or uneven wear.

• Suspension Problems: While less common, issues with your car's suspension components (like worn ball joints, tie rod ends, or control arm bushings) can contribute to shaking or vibration during braking. These worn parts can allow excessive movement in the wheels, which becomes more noticeable when the brakes are applied.

• Wheel Imbalance: Although wheel imbalance typically manifests as vibrations at certain speeds, it can sometimes be exacerbated during braking, especially if there are underlying brake system issues.
