When you’re driving, you don’t want to hear an unusual noise, such as a grinding or a high-pitched squeal, coming from your vehicle. A squeaking or squealing sound is particularly worrying when it happens as you apply your brakes. While fairly common, screeching halts can be traced to several reasons that often require brake repair or inspection from a skilled technician.

Reasons for Brake Repair With Squeaking Brakes

1. Loose Parts

Because the braking system is made up of numerous components, it’s likely that some of the pieces lack lubrication or have become loose. Unsecured parts, like an anti-rattle clip, can cause vibration on the pads, which lead to squealing sounds as you engage your brakes.

2. Worn Pads

Probably the most common reason why brakes squeak is worn out pads. Brake pads have metal wear indicators that, once exposed, produce a high-pitched noise whenever you hit the brakes. It serves as a warning to replace your brake pads or have them checked by an auto repair expert for underlying issues.  

3. Lack of Insulation Shims

Insulation shims come with brake pads and are placed against the steel backing plates to insulate against the caliper. They are effective in preventing brake squeals, but they tend to wear out over time. If you’ve had your brakes replaced, install shims or apply silicone insulation gel to reduce high-pitched noises.   

4. Glazed Pad & Rotors

There are instances when brake calipers get stuck, causing the pads to remain in contact with the rotors. The excessive friction causes the pads and rotors to overheat, harden, and crystallize. Glazed pads and rotors lead to diminished braking capability and squeaking noises. A brake repair expert can resurface the rotors to remove any glazing or uneven surfaces.  

5. Weather or Road Conditions

Sometimes, driving in unfavorable weather conditions, including heavy rain or snow, can cause squealing. When condensation gathers on the rotors, your pads will squeak if they haven’t fully warmed up before you apply the brakes. But if the noise persists, have it checked by a brake repair specialist.
