Moreover, a noisy brake can also be a safety hazard, as it can affect the performance of your car’s braking system. In this post, we will explore the possible causes of a car making noise when you brake, and provide you with some tips on how to diagnose and fix the issue.
Common Causes of a Car Making Noise When You Brake
There are several reasons why your car may be making noise when you brake. Some of the most common causes include:
Worn-Out Brake Pads
Worn-out brake pads are one of the most common causes of a car making noise when you brake. When brake pads wear down, they can cause the brake caliper to rub against the rotor, resulting in a squealing or grinding noise. This noise can be loud and persistent, and it can be a sign that your brake pads need to be replaced.
Here are some signs that your brake pads may be worn out:
- Squealing or grinding noise when you brake
- Soft or spongy brake pedal
- Vehicle pulling to one side when you brake
- Brake warning light on your dashboard
Warped Brake Rotors
Warped brake rotors can also cause a car to make noise when you brake. When brake rotors become warped, they can cause the brake pads to vibrate, resulting in a grinding or screeching noise. This noise can be loud and persistent, and it can be a sign that your brake rotors need to be resurfaced or replaced.
Here are some signs that your brake rotors may be warped:
- Grinding or screeching noise when you brake
- Vehicle pulling to one side when you brake
- Brake warning light on your dashboard
- Brake pedal feels spongy or soft
Loose or Worn-Out Brake Hardware
Loose or worn-out brake hardware can also cause a car to make noise when you brake. When brake hardware such as the brake caliper bolts or brake rotor screws become loose or worn out, they can cause the brake pads to vibrate, resulting in a grinding or screeching noise.
Here are some signs that your brake hardware may be loose or worn out:
- Grinding or screeching noise when you brake
- Vehicle pulling to one side when you brake
- Brake warning light on your dashboard
- Brake pedal feels spongy or soft
Brake Fluid Leaks
Brake fluid leaks can also cause a car to make noise when you brake. When brake fluid leaks out of the brake system, it can cause the brake pads to vibrate, resulting in a grinding or screeching noise.
Here are some signs that your brake fluid may be leaking: (See Also: Why Does My Steering Wheel Turn When I Brake? It’s Not Just You)

Diagnosing a car making noise when you brake can be a bit of a challenge, but it can be done with the right tools and knowledge. Here are some steps you can follow to diagnose the issue:
Check the Brake Pads
The first step in diagnosing a car making noise when you brake is to check the brake pads. You can do this by looking at the brake pads through the wheel well or by removing the wheel and inspecting the brake pads directly. If the brake pads are worn out, you may need to replace them.
Here are some tips for checking the brake pads:
- Look for signs of wear on the brake pads, such as thinning or scoring
- Check the brake pad thickness using a brake pad gauge
- Inspect the brake pads for any signs of damage or wear
Check the Brake Rotors
The next step in diagnosing a car making noise when you brake is to check the brake rotors. You can do this by looking at the brake rotors through the wheel well or by removing the wheel and inspecting the brake rotors directly. If the brake rotors are warped, you may need to resurface or replace them.
Here are some tips for checking the brake rotors:
- Look for signs of wear on the brake rotors, such as warping or scoring
- Check the brake rotor thickness using a brake rotor gauge
- Inspect the brake rotors for any signs of damage or wear
Check the Brake Hardware
The next step in diagnosing a car making noise when you brake is to check the brake hardware. You can do this by looking at the brake caliper bolts or brake rotor screws and checking if they are loose or worn out. If the brake hardware is loose or worn out, you may need to tighten or replace it.
Here are some tips for checking the brake hardware:
- Check the brake caliper bolts or brake rotor screws for any signs of wear or damage
- Check if the brake caliper bolts or brake rotor screws are loose
- Inspect the brake hardware for any signs of wear or damage
Check the Brake Fluid
The final step in diagnosing a car making noise when you brake is to check the brake fluid. You can do this by checking the brake fluid level and looking for any signs of leaks. If the brake fluid is low or leaking, you may need to top it off or replace it.
Here are some tips for checking the brake fluid:
- Check the brake fluid level using a brake fluid gauge
