What Causes Car Brake Screeching?
Before we dive into the solutions, it’s essential to understand what causes car brake screeching in the first place. There are several reasons why your car might be making this unpleasant sound, and we’ll explore them below.
Worn-Out Brake Pads
One of the most common reasons for brake screeching is worn-out brake pads. Brake pads are designed to wear down over time, and when they become too thin, they can cause the brake rotor to vibrate and make a screeching sound. This is often accompanied by a grinding or squealing noise.
Signs of Worn-Out Brake Pads
- Screeching or grinding noise when you brake
- Brake pedal feels spongy or soft
- Brake light comes on on your dashboard
- Brake pads are visibly worn down
Warped Brake Rotors
Another common cause of brake screeching is warped brake rotors. When brake rotors become warped, they can cause the brake pads to vibrate and make a screeching sound. This can be caused by excessive heat, improper brake pad installation, or even a minor accident.
Signs of Warped Brake Rotors
- Screeching or grinding noise when you brake
- Brake pedal feels spongy or soft
- Brake light comes on on your dashboard
- Brake rotors are visibly warped or damaged
Brake Caliper Problems
Brake calipers are responsible for applying pressure to the brake pads and rotors. When brake calipers become faulty, they can cause the brake pads to vibrate and make a screeching sound. This can be caused by worn-out seals, corrosion, or improper installation.
Signs of Brake Caliper Problems
- Screeching or grinding noise when you brake
- Brake pedal feels spongy or soft
- Brake light comes on on your dashboard
- Brake calipers are visibly damaged or corroded

Step-by-Step Guide to Resurfacing Brake Rotors
- Jack up the car and remove the wheel
- Remove the caliper and brake pads
- Use a brake rotor resurfacing tool to machine the rotors
- Reinstall the caliper and brake pads
- Lower the car and test the brakes
Inspect and Clean Brake Calipers
If your brake calipers are causing the screeching noise, you may need to inspect and clean them. Look for signs of corrosion, worn-out seals, or other damage. Clean the calipers with a wire brush and apply a rust-inhibiting coating to prevent further corrosion.
Step-by-Step Guide to Inspecting and Cleaning Brake Calipers
