When monitoring your brakes, it pays to develop a sensitive ear. One of the easiest ways to tell if your vehicle needs brake service is if you hear something unusual when you stop your vehicle. Here’s a guide to three sounds that indicate you should head to the auto repair shop. 

3 Sounds That Indicate You Need Brake Service

1. Grinding

A grinding noise as you use your brake usually means some detritus like a pebble has become lodged in the mechanism. Alternatively, it can signal that your brake pads have eroded, in which case you’ll need new ones. The sound comes from the pads creating friction against the rotor, which will wear down if the issue isn’t resolved with brake service.

2. Squealing

Many brake pads are built with small clips attached to them. They make a squealing sound when the pads have deteriorated, so consult a brake service expert as soon as you hear that noise.

One exception is if you hear the squealing the day after receiving a brake repair or replacement. While waiting for pickup, the vehicle can acquire a thin layer of rust on the rotor if it’s in an overly moist environment overnight. The squealing sound results when the brake pad sands off the rust. But if it continues for longer than a day, your brakes aren’t working properly.

3. Thumping

While less common, this noise can indicate a peskier and more difficult to diagnose problem. In the case of regular thumping, a vehicle with rear drum brakes has gotten its “braking shoes” out of sync. Brake shoes are curved plates that press against the back wheels to slow down or stop your vehicle. If you hit a pothole or drive over a decaying road, the brake shoes can move out of position and start banging against the wheels. Other potential consequences include reduced braking capacity and awkward sagging when you try to stop.
