Squealing Brakes? Common Brake Pad Problems and How to Fix Them
As a garage owner, I’ve heard my fair share of brake squeals. And let me tell you, that noise is more than just annoying. It’s often a cry for help from your car, signaling that something’s not quite right with the brake system. Don’t ignore it! Understanding the common problems behind those squeals and knowing how to address them can save you money and, more importantly, keep you safe on the road.
Identifying the Culprit: What’s Causing That Noise?
So, your brakes are screaming louder than a teenager at a boy band concert. The first step is to figure out what’s actually making the racket. Brake squeal isn’t always a sign of imminent disaster, but it’s certainly worth investigating.
- Worn Brake Pads: This is the most common reason for brake squeal. As brake pads wear down, a small metal indicator, often called a wear indicator or squealer, starts to rub against the rotor, creating that ear piercing sound. Ignoring this warning can lead to damage to the rotors, which is way more expensive to fix than just replacing the pads.
- Glazed Brake Pads or Rotors: Think of glazed donuts, only less delicious and more problematic. This happens when the brake pad material overheats and becomes hard and shiny, reducing friction and causing noise. It’s like trying to stop on ice.
- Debris and Rust: Road grime, dirt, and rust can accumulate on the brake components, especially if the car sits for extended periods. This debris can cause squealing and grinding noises
