The lifespan of brakes could last a long time, depending on how drivers treat the brake pads. Understanding how you drive is essential, as it can help you understand when to replace the brake pads. Brake pads typically last around 25,000 to 65,000 miles, but aggressive driving can cause that number to shrink. Braking hard and riding the brakes (when a foot is always on the brake pedal) places heat and pressure on your brakes and can lead to shrinking their lifespan. If screeching begins to happen, you should get them changed and think about adjusting how you drive to extend the pad's lifespan.
This may shock you, but one of the reasons for brake screeching is that your brakes are simply too new. Your vehicle's brake pads may require a few more trips to work to get accustomed to the car. In this case, weather conditions can lead to a build-up of moisture on your brake pads, and it can take a bit of time to get rid of that moisture. Additionally, your driving could create some brake screeching. Late braking or "riding" your brakes could cause brake squeaking, especially if they are new. If that's the case, then think about giving your brakes a rest to help reduce more heat.
Old brakes could be the reason you may experience that squeaking as well. Over the years, parts on every vehicle will likely begin to break down due to moisture, driving habits, if it is garaged or not, and rust. The simple solution is to just get them changed with new parts. However, a change in how you drive on the road could lower the screeching before taking them to the shop.
On any vehicle, problems may occasionally come from nowhere. Of course, frequent maintenance checks could give you the foresight to prevent future problems, but everyday issues could still occur. One of those issues might be screeching brakes, and there are some ways to avoid this, depending on if your brakes are brand-new or older. Brake squeaking is likely the result of your driving conditions and even driving habits.
