Brake system is reducing a speed of a thing by converting the kinetic energy into
another form. There are two types of brakes, such as disc brakes and drum brakes.
Maintenance of the brake system is routinely conducted at the time of service. Special
service tools (SST) is a tool used for an individual in working on or repairing
automotive components which cannot be carried out in the normal way. The research
aimed to design special tools of drum brakes cleaner. The result of the research
showed that the use of Service Special Tools saved more time in cleaning the brake
and drum pads compared to using sandpaper media. 80% from 10 respondents said
that they were satisfied with the result of brake pads and drum cleanser. Therefore, it
can be concluded that the use of special tools in cleaning drum brake is more efficient
than using sandpaper.
