What Causes the Brakes to Squeak When Pressed?
2 Answers
The reasons for squeaky brakes when pressed are: 1. Rust on the brake disc or brake pads; 2. Newly installed brake pads; 3. Excessive wear of the brake disc or brake pads; 4. Incorrect installation or mismatched model of brake pads; 5. Use of low-quality or overly hard brake pads; 6. Abnormal brake caliper or lack of brake fluid; 7. Presence of foreign objects between the brake drum or disc and the pads. Solutions for squeaky brakes include: 1. Applying grease or specialized lubricant at the connection between the brake pads and caliper; 2. Regularly inspecting and replacing brake pads; 3. Periodic brake adjustment; 4. Avoiding frequent use of brakes.
In my past driving experiences, I often encountered squeaking noises when braking, which were quite annoying. There are usually several common reasons for this. First, the brake pads may be worn too thin; when the thickness is insufficient, the metal parts rubbing against the brake disc can produce a sharp sound. Second, the surface of the brake disc may be rusty or have accumulated dust and debris, causing uneven friction when braking. Third, components may have aged or become loose, such as improperly fastened bolts on the brake calipers. Additionally, rust caused by rain or moisture can make the noise more noticeable after rainfall. I recommend first checking if the brake pads are nearly worn out. You can use a flashlight to inspect the gap—if you see the warning line, it's time to replace them. Don’t wait until the noise worsens to address the issue, as this can lead to reduced braking performance, making the car more prone to skidding or delayed response while driving. During every maintenance check, I’m reminded to pay attention to unusual noises and address minor issues promptly to avoid costly repairs and safety hazards. Now, I’m sharing this so others don’t overlook it like I did back then.
