There aren’t many sounds that come from your vehicle as uncomfortable as a squealing noise coming from your brakes. It’s as bad as nails on a chalkboard, but it’s also likely warning you of an issue in your brake system. In this article, we’ll go over the common causes of brake squeaking, how these issues occur, and how to prevent this in the future!
How Do Brakes Work?
Modern brake disc systems rely on a surprisingly simple process to slow your vehicle down. Using hydraulic fluid, the brake pedal transfers and amplifies its force through the brake lines to the calipers sitting on the rotors . Then, the hydraulic force causes the caliper to push abrasive brake pads down on the rotors surface to generate friction and slow the vehicle to a stop.
Why Are My Brakes Squeaking?
Worn Out Pads
Constant friction between the pads and rotors will cause both to degrade, wearing down the pads and ruining the smooth surface of the rotors. While wear is expected, pads can wear down to dangerous levels if left unreplaced.
Improper Installation
But what if your vehicle’s brake pads are brand new? It’s unlikely they’ve worn out already. In this situation, the problem is usually due to improper installation of the brake components. This often occurs when a part is incorrectly positioned and comes into contact with the brake rotor or another rotating component, resulting in that unpleasant squealing noise.
Weather Conditions
Not all brake squealing indicates a serious problem; in fact, you’ve probably heard a similar sound before when driving in the rain or snow. In most cases, this is due to the buildup of condensation on the brake rotors, causing the pads to rub against the wet rotors and producing an audible squeaking sound when braking .
The good news is, this condition is temporary as the condensation will burn off from the rotors fairly quickly. IF the noise continues, your issue may go beyond condensation and should be inspected by a professional.
Rust/Debris on Rotors
A buildup of rust or debris on your rotors can cause temporary brake squealing when sitting for long periods of time, especially outside. It’s possible for a light layer of rust and/or debris to develop on the surface of the brake rotors from humidity and moisture in the air. When initially braking, this rust can cause improper contact between the pads and rotors, leading to a squealing sound as the rust is rubbed away.
How to Prevent Brake Squeaking
There are a few steps owners can take to protect their vehicles’ braking systems from the issues mentioned above, including:
- Change brake pads and rotors as needed
- Use coasting and progressive braking to extend the life of friction components
- Use the parking brake when the car is off, especially on hills
- Clean your rotors using disc brake cleaner
- Keep the vehicle indoors to prevent condensation and rust build-up.
