Why Are My Brakes Squealing or Grinding? Causes and Fixes for Redding Drivers

Why are my brakes squealing or grinding? A squeal usually comes from the built-in wear indicator telling you the brake pads are nearly worn out. Grinding means the pads are gone and metal is scraping the rotors. Sticking calipers, warped rotors, and rust after rain can also cause brake noise.

Brake noise is your car asking for attention. A high-pitched squeal when you brake usually comes from a small metal tab built into the pad that touches the rotor when the pad is nearly worn out. A deep grinding sound means the pad material is gone and metal is scraping metal.

Common causes of brake noise

• Worn brake pads. The most common cause of squealing. Caught early, it's a simple pad replacement. Brake repair and service
• Worn or warped rotors. Grinding wears grooves into the rotors. Warped rotors also make the pedal or steering wheel pulse; see steering wheel shakes or vibrates.
• A sticking caliper. It keeps a pad dragging, which causes noise, heat, and often a burning smell.
• Rust or debris after rain or a wash. A light scrape that goes away after a few stops is usually harmless.
• Low or old brake fluid. It makes the pedal feel soft and can lead to corrosion. Fluid inspection

How we find the cause and fix it

1. We measure pad thickness and check rotors, calipers, hoses, and brake fluid.
2. You get photos of your brakes on your phone, with a clear inspection report.
3. We recommend only what's worn, and give you an estimate before any work.
4. We test drive the car after the repair to make sure it stops straight and quiet.

Is it safe to keep driving?

A squeal means book soon. Grinding means book now, because every stop is cutting into the rotors. If the pedal sinks toward the floor, the car pulls hard when braking, or the brake warning light is on, stop driving and call us.
