The light vehicle repair industry plays a crucial role in supporting public mobility, including in Padang City, where the number of repair shops continues to grow in line with the rise in private vehicles. However, most repair shops still operate conventionally, with limited human resources and technology. One common problem is low work efficiency in brake system maintenance, particularly in manual brake fluid bleeding, which is still performed manually and requires two technicians. This community service activity aims to improve the competence of workshop mechanics through training in the use of vacuum brake bleeders. The training was held at the Ken Autotech Workshop in Padang City, with 10 mechanics participating. The training included material delivery, demonstrations, hands-on practice, and ongoing mentoring. Results showed that before the training, most participants were unfamiliar with this tool, while after the training, 95% understood how it worked and 85% expressed interest in using it. Furthermore, 95% of participants stated that they felt direct benefits from the training. Thus, this training effectively improved mechanical understanding and skills and is relevant for wider application with the support of tool provision and further collaboration
