worn brake pads: As brake pads wear down, they can become thinner and start to vibrate against the brake rotor. This vibration can cause a squeaking or squealing noise.
rusty brake rotors: If the brake rotors are rusty, they can cause the brake pads to stick and squeak when you apply the brakes.
loose brake caliper bolts: If the brake caliper bolts are loose, they can allow the caliper to move around and cause the brake pads to rub against the rotor, resulting in a squeaking noise.
contaminated brake fluid: If the brake fluid is contaminated with dirt or water, it can cause the brake pads to stick and squeak.
To fix the problem, you should inspect the brake pads and rotors to see if they are worn or rusty. If they are, you will need to replace them. You should also check the brake caliper bolts to make sure they are tight. If they are loose, you will need to tighten them. Finally, you should have the brake fluid flushed and replaced if it is contaminated.
