Installation of disc brake

·Firstly, check the brake surface of the brake disc and brake pad for oil sludge or other stains.

·Install the G3/8 "(cast iron rod cylinder) or 1/2" (cast aluminum cylinder) connector on the air inlet of cylinder 1, connect the air pipe with a hose, and the air source should be free of oil, water, and other impurities

·When installing, first introduce pressure air to retract piston rod 5 into the cylinder, then install friction block 12 into the brake disc in the direction perpendicular to the brake disc, and then fix base 9 horizontally on the rigid base, so that its center is in line with the center of the brake disc thickness. The installation position dimensions are shown in the structural diagram

3、 Disc brake commissioning

·Adjust the air pressure value to a range of 5-7 bar.

·For normal work, the first step is to test the brake several times and check if there are any abnormalities in the brake.

·The retraction distance of the friction block can be adjusted by rotating the adjustment rod 6 to change the size of the working stroke. When rotating the adjustment rod, pressure air is first introduced to retract the piston rod, and then adjusted.

4、 Disc brake maintenance

When the friction plate is worn and the working stroke increases to 8mm, it is necessary to immediately adjust lever 6 to readjust the working stroke by about 4mm. Otherwise, the brake will fail. After adjustment, the nut 7 should be tightened. When the friction block 12 is worn to about 6mm, the wear block needs to be replaced. The replacement steps are as follows:

1. Cylinder, 2. Right brake arm, 3. Return spring, 5. Piston rod, 6. Adjusting rod, 7. Nut, 8. Left brake arm, 9. Base, 10. Brake block, 11. Spring steel wire, 12. Friction plate
