When the brake pads and rotor come into contact, they vibrate and create a high-pitched noise. This can be caused by a number of factors, including worn or contaminated brake pads, improperly aligned calipers, or a warped rotor. Another common cause of disc brake squealing is glazing. This occurs when the brake pads become overheated and the friction material is hardened. This can be caused by prolonged braking, riding down steep hills, or using the brakes too hard. Other potential causes of disc brake squealing include moisture, dirt or debris on the rotor, or a loose rotor. If you’re experiencing disc brake squealing, it’s important to diagnose the issue quickly and make any necessary repairs or adjustments.

Proper break-in procedure for new disc brake pads

Proper break-in procedure for new disc brake pads can help increase their lifespan and improve their performance. When you initially install new brake pads, they need to be broken in to ensure proper contact with the rotor and prevent glazing. To break in new brake pads, start by gradually increasing speed and lightly applying the brakes until you come to a complete stop. Repeat this process 10-15 times, allowing the pads to cool for a few seconds between applications. It’s important to avoid hard braking during the break-in period, as this can cause uneven wear and damage to the pads. After the break-in period, test the brakes to ensure they are working properly and adjust as necessary. Remember that proper break-in procedure is key to maximizing the performance and longevity of your disc brake pads.
