1. Improper installation: If the brake shoes are not installed correctly, they can rub against the brake drums and cause a squeaking noise. This is especially common if the shoes are not properly seated in the backing plate or if the brake springs are not properly attached.
2. Uneven wear: If the brake shoes are not wearing evenly, they can also cause a squeaking noise. This can be caused by a number of factors, such as a warped brake drum, a faulty brake caliper, or a problem with the brake fluid.
3. Glazed brake pads: If the brake pads are glazed, they can also cause a squeaking noise. This can happen if the pads have been overheated or if they have been contaminated with oil or grease.
4. Dirty brake drums: If the brake drums are dirty or rusty, they can also cause a squeaking noise. This can be caused by a number of factors, such as brake dust, road salt, or water contamination.
5. Defective brake shoes: In some cases, a squeaking noise can be caused by a defective brake shoe. This can happen if the shoe is cracked, chipped, or warped.
If you are experiencing a squeaking noise from your rear brakes, it is important to have it checked out by a qualified mechanic. They will be able to diagnose the problem and recommend the best course of action.
