1. When the vacuum valve and the diaphragm cannot be closely attached or the diaphragm is broken, the vacuum degree is weakened due to air leakage, so the boosting effect is reduced.

Low, making the brake pedal of the suction truck too heavy. At this time, the diaphragm or vacuum valve should be replaced.

. At this time, replace the piston seal.

3. The gap between the vacuum valve and the air valve of the suction truck is too small, which causes the air valve of the suction truck to close in advance, or because the air valve

Straight in the closed state, so that the assist effect is reduced, and the brake operation is heavy. At this time, replace the control valve (vacuum-air valve).

.

4. When the one-way ball valve of the hydraulic piston of the manure suction truck is not tightly closed, the high pressure oil of the manure suction truck returns to the cylinder due to oil leakage. So the suction truck

The brake pedal has a kick-back force, which makes the suction operation of the suction truck heavy. At this time, the hydraulic piston should be replaced.
