Caution: Some model motors may have a different number of springs (26). If there are not enough springs for the 12 spring mounting holes, have the empty holes facing each other diagonally as in the cross-section diagram. If empty holes are clustered on one side, the parking brake effectiveness may deteriorate.
Caution: • Place the spherical side of the valve plate (5) upwards to attach it. • Thoroughly apply grease (*2) to the matching surface between the base plate (2-1) and valve plate (25) to prevent the valve plate (5) from falling. • Be careful not to scratch the valve plate (5) spherical surface.
