Product Description
Product Overview
Railway freight rolling stock composite brake shoes are high-friction brake blocks designed for heavy-duty freight car braking applications. These components directly contact wheel treads during train operation and braking, utilizing friction to safely stop train movement.

- Environmentally friendly - contains no lead, zinc, or toxic materials
- No unpleasant odor generation during friction operations
Product Variants
High Friction Composite Brake Shoe (H)
Designed for applications requiring maximum braking force with friction coefficients ranging from 2.8 to 3.2.
Low Friction Composite Brake Shoe (L)
Suitable for operations where controlled, lower friction braking is preferred.
Note: H-type and L-type brake shoes are not interchangeable with each other or with cast iron brake shoes.
