Dust is sticking to the ground.
The braking force and the amount of stepping to lock are better than OEM and easy to handle, but Dust is a little too much. Because it is not easy to fall, even if Drum rotates, it seems that Dust does not escape because it feels like Dust sticks to it, and Dust was attached to the Bear Ring seal. even more so since the meter gear is also available.
The picture I took of the panel that was all burnt brown and cleaned with Brush and Parts cleaner, but it really doesn't flow.
