No matter how carefully you drive, scheduled maintenance needs to be done at some point. In addition to aspects like oil changes and tire rotations, brake repairs are unavoidable, which is obvious when they make a noise like squealing. However, not all noisy brakes need to be taken in as part of the scheduled maintenance, so it’s important to understand the various causes of this sound.

Why Your Car’s Brakes Squeal

1. Moisture Accumulation

When a vehicle is left out overnight, the moisture from rain, dew, or condensation collects on the surface of the vehicle’s rotors. This forms a thin layer of rust on the surface, and when you start driving, the pads scrape the rust off of the rotors. As these fine rust particles get caught on the edge of the brake pad, it causes the squeaking noise. You don’t need maintenance for moisture-related squealing.

2. Too Much Metal in Brake Pads

While most brake pads contain some bits of metal, less expensive options have a higher concentration. These larger pieces of metal drag on the rotor, causing the high-pitched squeak heard from the brakes. These types of brakes may also cause discoloration in chrome and aluminum wheels. If the noise bothers you, scheduling service for different pads will do the trick, but it’s not necessary.

3. Worn Down Brake Pads

This is the most common cause for the unpleasant sound and a surefire indication you should schedule maintenance. Through normal wear and tear from driving, the brake pads become thinner, which makes them less effective. Manufacturers install wear indicators that cause the noise to remind drivers they need to take their cars to an auto mechanic.
