Features: 1. The pads are made of brass particles, iron particles, synthetic resin, and then matched with metal to make the bottom plate for stamping. 2. The surface is smooth, and the brass particles are fused in the resin fiber to conduct heat, accelerate heat dissipation, and maintain braking performance. 3. Long-term applicability, in case of oil and dirt, it can still be used after being polished with abrasive paper. 4. High temperature resistant resin, metal baking, heat dissipation performance, improve the shear strength and pressure resistance of the friction block.
