The Ultimate Guide to Choosing brake drum 0310677560

Types of BPW drum brakes

A drum brake system is a foundational technology in automotive braking systems, especially prevalent in commercial and heavy-duty vehicles. The design relies on friction generated between the brake linings and the internal surface of the rotating drum to decelerate or completely stop wheel rotation. Attached directly to the wheel hub, the brake drum rotates along with the wheel. When the driver applies the brakes, mechanical or pneumatic force pushes the brake shoes outward, pressing them against the inner surface of the drum, creating the necessary friction to reduce speed or halt movement.
