The brake pads are critical friction components in railway vehicle braking systems, paired with brake discs to convert kinetic energy into thermal energy via friction, enabling safe deceleration or stopping of rolling stock. Typically composed of a friction material layer and a steel backing plate, they feature high wear resistance, stable friction coefficient, and excellent heat dissipation. Brake pads are widely used in high-speed EMUs, freight locomotives, and urban rail transit vehicles, requiring regular inspection and replacement to ensure braking performance and operational safety.
Installation
Composite brake pads usually adopt a dovetail-type installation. Their steel back is designed with dovetail grooves, which precisely engage with the dovetail tenon of the brake caliper for positioning, and are supplemented by bolts or elastic clamping to achieve firm fixation.
