What are the symptoms of a faulty brake drum?
2 Answers
After the brake drum is damaged, symptoms such as brake failure, abnormal noises during braking, and brakes sticking without returning to position may occur. Here is more information: 1. Application of drum brakes: Due to their reliability and strong braking force, drum brakes are still installed on many vehicle models today. They are fixed to the tires and rotate at the same speed. During braking, hydraulic pressure is used to push the brake shoes against the inner edge of the brake drum, generating friction to inhibit the rotation of the tires and achieve the braking purpose. 2. Principle of drum brakes: Drum brakes utilize stationary brake shoes inside the brake drum to rub against the rotating brake drum attached to the wheel, creating friction to reduce the wheel's rotation speed as a braking mechanism.
I previously encountered a broken brake drum, and the symptoms were quite noticeable while driving. The brake pedal felt spongy when pressed, like stepping on a sponge, making it nearly impossible to stop without applying extra force. Additionally, the vehicle emitted a harsh metallic scraping noise, especially during turns or sudden braking, which was incredibly annoying. The wheel hub also tended to overheat—after stopping, touching the wheel would burn your hand. This could lead to brake failure or even pose a fire hazard. Regular maintenance is crucial: check the wear on the drum brakes periodically, ideally every 10,000 kilometers or so. Identifying issues early can prevent costly repairs, as replacing the entire drum brake system can cost upwards of a thousand dollars. Safety comes first—don’t ignore these warning signs. Get them addressed promptly by a professional auto repair shop.
