How to adjust the brakes of Sany Heavy Industry mixer

How to adjust the brakes of mixer truck of Sany Heavy Industry?

1. Spray some clean water on the brake adjusting knob of mountain bike first, and rinse the sludge on the screw to facilitate adjustment.

2. After that, pull back the brake lever and test the tightness of the brake. I feel that the brake is a little too tight because of the large resistance, and I need to let it go. The brake is a little loose because of the low resistance, so I need to tighten it.

3. After that, turn the brake screw with a wrench. If you turn outward, the brakes will loosen, and if you turn inward, the brakes will tighten.
