What Causes Squeaky Brakes in Sedans?
2 Answers
The reasons for squeaky brakes in sedans are as follows: 1. The brake pads are worn out, leaving only the metal backing to rub against the brake rotor. 2. When the brake pads are nearly worn out, the warning tab rubs against the rotor, alerting the driver to replace the brake pads. 3. Newly replaced brake pads may be too hard, causing noise during friction. 4. Small stones may have fallen into the brake assembly, leading to squeaky brakes. Here are the main solutions for resolving brake noise: 1. Check if the brake pads are nearly worn out. If they are, replace them with a new set. Typically, brake pads have a wear indicator that makes contact with the rotor when the pads are sufficiently worn, producing a metallic squeal. 2. If the pads are new, check for any foreign objects caught between the pads and rotor. 3. If newly replaced brake pads and the rotor are free of debris, the noise is likely due to a break-in period required between new brake pads and the existing rotor.
I've encountered the issue of squeaky brakes quite a few times, mainly caused by prolonged vehicle use or improper driving habits. The most common reason is excessively worn brake pads – when they get too thin, that friction noise starts appearing. Frequent hard braking accelerates this wear process. Another scenario is when brake discs get moisture or rust after rain, producing sharp squealing sounds during the first few brake applications that disappear after driving for a while. Additionally, dust or small stones getting lodged in the braking system can cause trouble, especially when driving on construction sites or muddy roads. I recommend regularly checking brake pad thickness and replacing them promptly when worn – don't wait until the noise becomes a safety hazard. Finally, don't skip lubrication maintenance, as insufficient lubrication of caliper pins can also cause annoying noises. These simple measures can make driving much safer, because safety should always come first.
