What does a band brake mean?
3 Answers
It utilizes friction to reduce rotational speed, achieving the purpose of deceleration and stopping. More extended information is as follows:1. Band Brake: The principle of a band brake is basically the same as that of an expanding brake, but structurally, the brake lining is on the outside while the hub is on the inside. When the brake pedal is pressed, the brake lining clamps inward to embrace the hub.2. Expanding Brake: Mainly composed of brake linings and a brake hub, the brake hub is a circular, hollow metal disc, resembling the shape of a cooking pot lid, with its center point connected to the wheel or axle; inside the hub, there are two semi-circular brake linings that meet. Since the brake linings are semi-circular, the two pointed ends of each lining correspond to each other. One end of the meeting point is a cylindrical shaft, and the other end is an oval shaft. When the brake is pressed, the oval shaft rotates, causing the semi-circular brake linings to separate outward, and the outer side of the linings rubs against the hub, creating resistance to reduce speed.
I've been driving for over a decade and experienced brake drag a few times – it's really unpleasant. Simply put, brake drag is when the brakes don't fully release after you take your foot off the pedal, causing the tires to lock up. Common causes include rusted brake pads or fluid blockages, especially after heavy rain or prolonged parking. The consequences are serious: accelerated tire wear, skyrocketing fuel consumption, and the dangerous risk of losing control during turns – particularly scary on highways. Last time it happened to me, the steering wheel started shaking, so I rushed to the repair shop for a brake system flush. Prevention is straightforward: regular brake maintenance, avoiding extended parking, and testing brake response with gentle presses before driving. Safety first – if you notice any dragging sensation, get it checked immediately.
I often hear people mention 'dragging brakes,' which means the brakes don't fully release after being applied, preventing the tires from rotating freely. This usually happens to the rear wheels due to rusted brake drums or calipers, or air bubbles in the brake lines. If you feel the wheels dragging while driving or smell burnt rubber, stop immediately to check, to avoid tire damage or accidents. The issue might also stem from ABS system failures or deteriorated brake fluid, so I change my brake fluid every six months to prevent this. Maintenance-wise, cleaning the brake components can often solve the problem. Safe driving is crucial, so address any issues promptly without delay.
