Driving a vehicle is a common experience for many people, and it’s essential to ensure that the vehicle is in good condition to avoid any accidents or injuries. One of the critical components of a vehicle is the braking system, which is responsible for slowing down or stopping the vehicle. However, when the brake pedal starts shaking when braking, it can be a cause for concern. This phenomenon is known as brake pedal vibration or brake pedal shake, and it can be a sign of a more serious issue with the vehicle’s braking system.
The brake pedal shake can be caused by various factors, including worn-out brake pads, warped brake rotors, loose brake calipers, or uneven brake wear. If left unaddressed, the brake pedal shake can lead to a loss of control of the vehicle, which can result in accidents or injuries. Therefore, it’s essential to identify the cause of the brake pedal shake and address it promptly.
In this article, we will discuss the causes of brake pedal shake when braking, the symptoms, and the steps to diagnose and repair the issue. We will also provide some tips on how to prevent brake pedal shake and maintain the braking system of your vehicle.

Causes of Brake Pedal Shake When Braking
The brake pedal shake can be caused by various factors, including:
- Worn-out brake pads: Over time, the brake pads can wear out, causing the brake pedal to shake when braking.
- Warped brake rotors: If the brake rotors are warped or damaged, it can cause the brake pedal to shake when braking.
- Loose brake calipers: If the brake calipers are loose, it can cause the brake pedal to shake when braking.
- Uneven brake wear: If the brake pads are worn out unevenly, it can cause the brake pedal to shake when braking.
- Brake fluid leaks: If there is a leak in the brake fluid system, it can cause the brake pedal to shake when braking.
- Master cylinder problems: If the master cylinder is faulty, it can cause the brake pedal to shake when braking.
Worn-out Brake Pads
The brake pads are a critical component of the braking system, and they can wear out over time. When the brake pads are worn out, it can cause the brake pedal to shake when braking. The symptoms of worn-out brake pads include:
- Squealing or grinding noise when braking
- Shaking or vibrating of the brake pedal
- Increased stopping distance
- Soft or spongy brake pedal
To diagnose worn-out brake pads, you can perform a visual inspection of the brake pads. If the brake pads are worn out, they will be thin and may have a shiny surface. You can also use a brake pad wear gauge to measure the thickness of the brake pads.
Warped Brake Rotors
The brake rotors are another critical component of the braking system, and they can become warped or damaged over time. When the brake rotors are warped or damaged, it can cause the brake pedal to shake when braking. The symptoms of warped brake rotors include:
- Squealing or grinding noise when braking
- Shaking or vibrating of the brake pedal
- Increased stopping distance
- Brake pedal pulsation
To diagnose warped brake rotors, you can perform a visual inspection of the brake rotors. If the brake rotors are warped or damaged, they will have a rough or uneven surface. You can also use a brake rotor thickness gauge to measure the thickness of the brake rotors. (See Also: Which Side Is the Front Brake on a Scooter? Safety Essentials)
Diagnosing the Cause of Brake Pedal Shake
To diagnose the cause of brake pedal shake, you can perform a series of tests and inspections. Here are some steps to follow:
-
Check the brake fluid level and condition. If the brake fluid level is low or the brake fluid is contaminated, it can cause the brake pedal to shake when braking.
-
Inspect the brake pads and rotors for wear or damage. If the brake pads or rotors are worn out or damaged, it can cause the brake pedal to shake when braking.
-
Check the brake calipers for loose or damaged components. If the brake calipers are loose or damaged, it can cause the brake pedal to shake when braking.
-
Check the brake master cylinder for leaks or damage. If the brake master cylinder is faulty, it can cause the brake pedal to shake when braking.
-
Perform a brake test to check the braking performance of the vehicle. If the vehicle is not stopping properly, it can cause the brake pedal to shake when braking.
Repairing the Brake Pedal Shake
Once you have diagnosed the cause of the brake pedal shake, you can start repairing it. Here are some steps to follow:
-
Replace the worn-out brake pads or rotors. If the brake pads or rotors are worn out, replace them with new ones. (See Also: Noise When Pressing Brake Pedal? Don’t Ignore It!)
-
Adjust or replace the brake calipers. If the brake calipers are loose or damaged, adjust or replace them.
-
Replace the brake master cylinder. If the brake master cylinder is faulty, replace it with a new one.
-
Perform a brake bleed to remove any air from the brake system. If there is air in the brake system, it can cause the brake pedal to shake when braking.
Preventing Brake Pedal Shake
To prevent brake pedal shake, you can follow these tips:
- Regularly check the brake pads and rotors: Regularly check the brake pads and rotors for wear or damage.
- Replace the brake pads and rotors on time: Replace the brake pads and rotors on time to prevent wear and tear.
- Check the brake fluid level and condition: Regularly check the brake fluid level and condition to prevent brake fluid leaks.
- Perform regular brake tests: Perform regular brake tests to check the braking performance of the vehicle.
