At the heart of wheel bearing drum brakes is the drum brake mechanism, which consists of a drum mounted on the wheel and brake shoes that press against the inner surface of the drum to create friction. The wheel bearings support the axle and allow the wheel to spin freely while maintaining stability. When the brake pedal is pressed, hydraulic fluid travels through the brake lines and actuates the brake shoes, pressing them against the drum. This friction causes the vehicle to slow down or come to a halt.

Si vous constatez que certaines pièces sont usées ou endommagées, il est impératif de les remplacer. Les garnitures de frein, par exemple, doivent être en bon état pour assurer une performance optimale. Dans le cas contraire, elles peuvent se déformer et causer un collage.

まず、ブレーキドラムの基本的な役割について説明します。ブレーキドラムは、ブレーキシューが押し付けられたときに摩擦を生じ、その摩擦力によって車両を減速させる部品です。特に大型トラックの場合、荷物の重さや走行条件により高いブレーキ性能が求められます。このため、ブレーキドラムは耐摩耗性に優れた素材で作られ、効率的に熱を放散できる設計が求められます。

The rear brake system is often overlooked compared to the front brakes; however, it is equally important. While front brakes handle a significant portion of the stopping power, the rear brakes help to stabilize the vehicle during braking. Properly functioning rear brake drums and shoes help to ensure that the vehicle remains stable, particularly during emergency stops or when towing loads.

Disc Brakes In contrast, disc brakes utilize a flat disc (the rotor) that is attached to the wheel. Calipers, which house the brake pads, squeeze the pads against the disc when the brakes are engaged. The resulting friction between the pads and the disc slows the vehicle. Disc brakes often feature cooling vents or slots between the rotor's surfaces to dissipate heat, making them more efficient at maintaining performance during prolonged use.
