Causes of Dragging Disc Brakes @MotorcycleCareTips 

Causes of disc brakes dragging: 1 dry and drag caliper axle 2 master pistons are stuck or not moving smoothly 3. The wheel bearings are worn, causing the disc to not rotate in the center 4 The brake fluid is too full in the reservoir During this work, the front disc brake felt dragging due to the caliper piston not moving smoothly. This is caused by the dust seal being stretched. The solution is to disassemble the master piston and then clean all the component parts with water and soap. After that, sand the part of the dust seal that is already stretched so that when it is installed it doesn't cause the master piston to drag.
