What Causes Squeaking Brake Discs?

[DelSerenity]

The reasons for squeaking brake discs include using inferior brake pads, severe wear of the brake discs, and foreign objects between the brake pads and discs. Below is an introduction to the causes of squeaking brake discs: 1. Causes: (1) Use of inferior or overly hard brake pads. (2) Presence of sand or foreign objects between the brake pads and discs. (3) Severe wear of the brake discs, especially if inferior brake pads are used or hard foreign objects get between the pads and discs. (4) Brake pad wear indicator. Many people are unaware of how many kilometers brake pads should be replaced. 2. Solutions: If the issue is due to hard spots, the simplest method is to drive in reverse at about 5 km/h and apply the brakes several times, which usually removes the hard spots.

I've been driving for decades and have encountered squeaky brake discs quite often. The most common reason is that the brake pads are nearly worn out, and the metal backing plate rubbing against the disc creates noise, like an alarm reminding you it's time for replacement. Rust on the brake disc surface is also an issue, especially after parking overnight following rainy weather, causing squeaking when starting in the morning—though it usually stops after a few minutes of driving to wear off the rust. Other possibilities include dust or small stones stuck between the pads, or lack of lubrication in the pins, leading to abnormal friction. Don't underestimate such sounds; they indicate that the brakes might not be as responsive, and delaying repairs could affect driving safety, increasing emergency braking distances. I make it a habit to briefly inspect the brakes after each car wash and head to a professional repair shop immediately if anything seems off—spending a little money to save lives. Regular maintenance is crucial; keeping the system clean can prevent many troubles.

I often tinker with my car and modify small parts. The squeaky brakes are quite annoying, so my first suspicion is that the brake pads are too thin—if a visual check shows insufficient thickness, I replace them with new discs and pads. If the disc surface is uneven or rusty, I lightly sand it with sandpaper to remove the stains; if debris is stuck, I clean the shims. Don’t overlook lubrication—dry pins can easily cause noise, so adding some specialized grease quiets them down. Low-quality parts also cause trouble, so I prefer branded products to avoid counterfeits. Safety comes first when working on the car; if you don’t understand the electrical system, don’t tamper with it—leave it to a repair shop for peace of mind. Get into the habit of monthly visual inspections to extend the brake system’s lifespan, saving money and staying practical.

As a new driver, I was a bit panicked when I heard the brake discs squeaking for the first time. Others told me that common causes include brake pads being nearly worn out, or rust on the discs that acts up in wet weather. There might also be dust stuck in the gaps causing friction noises. It's important to get it checked promptly to prevent brake issues that could lead to accidents. I'll contact the repair shop right away to describe the symptoms and have them investigate thoroughly. Safe driving is the top priority, so don't take risks by delaying repairs.
