Composite Brake Shoe
There are two types as following:
1. High Friction Composition Brake Shoe
(The brake is fitting for the locomotive which speed is less than 120km / h)
2. Low-Friction Composition Brake Shoe
(The brake is fitting for the locomotive which speed is less than 95km / h)

2. Low-Friction Composition Brake Shoe
(The brake is fitting for the locomotive which speed is less than 95km / h)
A. The Mechanical Properties:
Brinell Hardness: ≤180Mpa
Impact Strength: ≤1.8KJ/M2
Compressive Strength: ≥25Mpa
B. Average Friction Coefficient:
| Speed Km/h | 55 | 60 | 75 | 80 | 95 | 100 | 1 20 |
| High Friction (COF) | - | 0.3 | - | 0.29 | - | 0.285 | 0.28 |
| Low-Friction (COF) | 0.16 | - | 0.15 | - | 0.14 | - | - |
