This is a serious issue that requires immediate attention, as it can damage the rotors and compromise braking performance. The brake caliper houses the brake pads and uses hydraulic pressure to squeeze them against the rotor. Wheel Trueness And Spokes: A wheel out of true can cause inconsistent rotor alignment to the pad, resulting in intermittent rubbing sounds. You have a bent brake rotor and the noisy spot is where the rotor is rubbing the pads if the brake rub is more rhythmic and intermittent. These imperfections can cause the brake pads to vibrate or rub unevenly, resulting in squealing, grinding, or pulsating sensations during braking. 5 When the brake caliper mounting bracket bolts are tightened to the hub (on the passenger side only!), the new rotor binds against the bottom of the bracket on the outside (away from the center of the vehicle) and the wheel cannot rotate freely. This rubbing creates a high-pitched squealing sound, alerting the driver that it’s time for a brake pad replacement. Faulty Calipers: The brake calipers house the brake pads and press them against the rotors when you apply the brakes. Besides, if your rotors are bent, you may face the same problem. The brake caliper houses the brake pads and uses hydraulic pressure to press them against the rotors. Bicycle caliper brakes have spring tension adjustment built into the calipers, and you can turn a screw to change the tension on your brake caliper, which will move the brake pad away from the wheel. Foreign objects like small stones, mud, or debris lodged between the brake rotor and caliper or inside the tire tread can also produce tactile and audible rubbing. Apply a small amount of brake-specific lubricant to moving parts to reduce friction and improve braking efficiency. Most brake pads have a built-in wear indicator, often a small metal tab, that begins to rub against the rotor when the pads reach a certain level of wear. If the rubbing noise continues, check the alignment of the brake calipers.
