The use of inert filler in the brake pad is considered only to reduce the manufacturing cost. However, it can contribute to the improvement of friction characteristics in a certain composition. The experimental study investigates the friction characteristic of non-asbestos brake pad composite by combining BaSO4 and friction dust as filler. Five samples with the volume fraction of BaSO4 to friction dust (30:0; 25:5; 20:10; 15:15; and 10:20 respectively) have been prepared. The samples have been compacted under pressure 47MPa and heated at a temperature of 150 °C simultaneously for 15 min. Then, they have been post-cured at a temperature of 150 °C for 6 hours. The friction characteristic has been tested using a Chase friction machine based on SAE J661. Friction characteristics are evaluated in the condition of friction-baseline, friction-fade, friction-recovery, and wear. The result reveals that the sample with a combination of BaSO4 and friction dust improves the second fade performance, the second recovery performance, the friction stability, and the wear resistance. Comprehensively, the optimal ratio BaSO4 friction dust (20:10 vol.%) has showed the lowest second fade performance (4.88%), a good second recovery performance (113.69%), and the highest friction stability (91.25%). This combination has potential as a functionally feasible brake pad filler for brake reliability and safety
