Do Break Squeaks Mean You Have A Problem?
Your brakes shouldn't squeak when you apply them. If they do, they could indicate you need brake repair. However, not all squeaking incidences mean you need to run to the repair shop right away. The trick to knowing whether you need repair is to know what your brake squeaks mean. Keep reading to learn more about why automobile brakes squeak and when you should take your car in for repairs.
Why Do Disc Brakes Squeak?
Disc brake squeak is rare. Usually, metal pieces rubbing together are the primary cause. The design of the disc brakes ensures that this problem is unlikely when the brakes are in good condition. Occasionally, moisture and dust buildup will cause some squeaking, but that will go away once you have driven around a little.
Other reasons why disc brakes squeak include:
- Rust on rotors and hardware
- Worn pads
- Warped rotors
- Glazed brake pads
- Brake and rotor contamination
If any of the above applies to you, take your vehicle to a mechanic for a brake checkup.
Why Do Drum Brakes Squeak?
Rear drum brakes tend to emit more noise than disc brakes. They have a more complicated design with many hardware pieces. However, drum brakes shouldn't squeak excessively. Like disc brakes, drum brakes will make extra noises when dust and moisture enter the drum. You will likely hear a squeak when you back up your vehicle.
Other reasons why your drum brakes may squeak include:
- Lack of lubricant on the backing pad
- Worn shoes
- Brake contamination
- Poor adjustment
- Drums in need of turning
All of the above indicates that you may need to see your mechanic.
When Is a Brake Squeak Serious?
Any time you have squeaking brakes combined with a lack of stopping power is serious. These symptoms indicate your vehicle's brakes need repair and service. You should also immediately take your car in for brake service if the pad wear indicator makes noise. Often, this noise gets so loud and frequent that you can't ignore it.
If you see grooves or scratches on your rotor, don't drive any further. This damage is an indicator that your pads are completely worn. Likewise, if your drum brakes pull or make a clunking noise in addition to a squeak, stop driving.
An occasional squeak that goes away after you've been driving for a while shouldn't be a problem. However, if your brakes squeak regularly or squeak very loud, then you may have an issue. Regardless of whether your brakes make noise, have your brakes checked as a part of your vehicle's regular service.
