What Causes Rear Brake Noise?

[AnthonyMarie]

The reasons for rear brake noise are: 1. Releasing the brake too slowly; 2. Newly replaced brake pads not properly worn in; 3. Sand particles entering between the brake pads and brake disc; 4. Missing or damaged brake disc fixing screws; 5. Brake system malfunction. Methods for brake maintenance include: 1. High-temperature protection to prevent brake system corrosion, avoid brake pads seizing due to high temperatures, and eliminate brake squeal; 2. Regular replacement of brake fluid; 3. Cleaning oil stains, dirt, and friction dust from brake discs, brake drums, and any components to maintain good heat dissipation of the brake disc; 4. Regularly checking the thickness of brake pads or brake shoes.

When I first started driving, I also encountered this issue. Squeaking rear brakes are mostly caused by brake pads being too thin or brake discs rusting, especially after rainy days. I've tried cleaning the brake discs and pads myself - sometimes dust buildup can get stuck and cause squeaking, but don't mess with it too much or you might make it worse. You need to check the entire braking system, like whether the brake fluid level is normal and if there's abnormal tire wear. If the noise is loud or persistent, go to a professional shop immediately to avoid increased braking distance leading to accidents. Normally, have a technician inspect your brakes every six months to extend component lifespan - it's safe and worry-free. With over 20 years of driving experience, I can honestly say this advice works.

My rear brakes used to make annoying noises, and after checking online forums, many friends mentioned several common causes. Poor quality or aged brake pads can cause noise, and improper installation or looseness can also easily lead to issues—you can try cleaning the dust yourself. However, this is only a temporary fix. It’s important to quickly check whether the brake discs are even, as the bearings might be damaged. On a related note, if you’ve modified the rear brake components, abnormal noises are more likely to occur, so it’s best to choose OEM parts during maintenance. In short, don’t ignore the issue—noises are often a sign of wear. Address it early to avoid additional costs and safety hazards.

For ordinary drivers, rear brake noise can be very dangerous. I experienced it once and found it was due to excessively worn brake pads. After replacing them, the issue was resolved. It's essential to check the brake discs for scratches or rust, and clean them if there's excessive dust. If not addressed promptly, braking performance will decline, posing greater risks during rainy weather or emergency stops. I recommend having the brake thickness checked during every maintenance service—don't delay or skimp to save money and invite bigger trouble. Safety comes first; if you hear noise, pull over safely before troubleshooting.
