Following is the details structure and technical data of DBM hydraulic disc brake for your reference:

According to this above torque table, we can know that the braking torque may vary dependenting on air pressure and braking disc diameter. Air pressure higher, braking torque is higher, when braking disc diameter bigger, DBM10 DBM20 braking torque are larger, too.

DBM hydraulic brake can be used in wet and oil environment. Before usage, it should empty the air in the connect pipe after installation. Proper installation is also very important, following is the instruction of it, hope it is helpful for you.
