The experience of Steering Wheel Shakes When Braking can be alarming and potentially dangerous for drivers. This phenomenon can be indicative of underlying issues with the braking system and requires immediate attention.
According to the National Highway Traffic Safety Administration (NHTSA), braking-related problems were the leading factor in approximately 22% of all vehicle crashes in the United States in 2021.
A study conducted by the American Automobile Association (AAA) found that steering-related issues, including vibrations during braking, accounted for 12% of all vehicle-related breakdowns in 2020.
In a survey by a leading automotive magazine, 65% of respondents reported experiencing steering wheel shake while braking in their vehicles at some point.
Here, we will delve into the various causes of steering wheel shake during braking, provide statistical data to support our findings, and offer real-life examples. Also, we will present actionable solutions to address the problem effectively.
Understanding Steering Wheel Shakes When Braking:
Steering wheel shake, commonly known as brake pulsation, occurs when the driver applies the brakes and feels vibrations transmitted through the steering wheel. This issue can range from mild to severe, with more severe shaking often accompanied by brake pedal pulsation and extended stopping distances.
Possible Causes of Steering Wheel Shakes When Braking:
Brake Rotor Warping:
As mentioned earlier, warped brake rotors can result from uneven expansion and contraction due to the heat generated during braking. This issue can occur gradually over time and is often noticed when braking at higher speeds.
According to a study conducted by the National Highway Traffic Safety Administration (NHTSA), brake-related problems, including rotor warping, accounted for approximately 22% of all vehicle-related accidents.
Uneven Brake Pad Deposition:
Uneven brake pad deposition refers to the uneven distribution of brake pad material on the rotor surface. This can lead to brake pulsation, causing the steering wheel to shake during braking.
The problem can be exacerbated by issues with the caliper or brake hardware. According to the Automotive Aftermarket Suppliers Association (AASA), brake-related issues are one of the top reasons for vehicle visits to repair shops, making up approximately 18% of all visits.
Suspension and Steering Components:
Worn or damaged suspension and steering components play a significant role in causing vibrations felt through the steering wheel. For example, worn ball joints, tie rod ends, or wheel bearings can lead to wheel wobbling during braking.
According to a study conducted by the American Automobile Association (AAA), faulty suspension components accounted for nearly 12% of all roadside breakdowns.
Brake Pad Wear:
Brake pads undergo significant wear over time due to repeated friction against the rotors. As the brake pads wear down, the amount of material available to create friction decreases, leading to reduced braking efficiency.
Additionally, worn brake pads can create uneven pressure on the rotors, causing vibrations in the steering wheel during braking. It’s important to regularly check and replace brake pads as recommended by the vehicle manufacturer to maintain optimal braking performance.
Rotor Runout:
Rotor runout refers to the lateral movement or “wobbling” of the brake rotor as it rotates. Excessive rotor runout can be caused by improper installation, wheel hub issues, or uneven brake pad deposition.
When the rotor wobbles during braking, it can lead to irregular contact with the brake pads, resulting in vibrations that are felt through the steering wheel. Proper rotor installation and regular maintenance can help prevent rotor runout and ensure smooth braking.
Tires and Wheel Alignment:
Tire-related issues can contribute to steering wheel shake, especially during braking. Imbalanced or improperly aligned tires can cause vibrations that are transferred to the steering wheel. Furthermore, uneven tire wear can exacerbate the problem. It is one of the main causes of Steering Wheel Shakes When Braking.
The Rubber Manufacturers Association (RMA) reported that around 66% of vehicles have at least one tire that is either over- or under-inflated, affecting overall vehicle performance.
Brake Pad Glazing:
Brake pad glazing occurs when the brake pads become overheated, causing the friction material to harden and create a glossy surface. This reduces the pad’s ability to grip the rotor effectively, leading to vibrations and reduced braking performance.
According to the Society of Automotive Engineers (SAE), brake pad glazing is a common issue in heavy-duty vehicles and is responsible for nearly 15% of braking-related problems in commercial trucks.
Brake Fluid Contamination:
Contaminated brake fluid can compromise the performance of the braking system and lead to vibrations during braking. Moisture and air can find their way into the brake fluid over time, reducing its effectiveness and causing the brake pedal to feel spongy.

The Motorist Assurance Program (MAP) reported that nearly 7% of vehicles have contaminated brake fluid, affecting overall braking performance.
Rotor Thickness Variation (RTV):
Rotor Thickness Variation refers to uneven rotor thickness, which can result from wear, improper machining, or uneven heating during braking. RTV can lead to vibrations and pulsations in the steering wheel during braking.
According to a study by the Automotive Parts Manufacturers’ Association (APMA), approximately 10% of vehicles on the road have rotor thickness variation issues.
Brake Caliper Sticking:
A sticking brake caliper fails to retract properly, causing constant friction between the brake pad and the rotor. This can lead to excessive heat buildup, warping the rotor and causing vibrations during braking.
The International Carwash Association (ICA) reported that nearly 9% of vehicles experience brake caliper sticking at some point in their lifetime.
