The brake system lacks necessary maintenance. There are too many impurities in the brake master cylinder, the seal is not tight, the vacuum booster pump fails, the brake oil is too dirty or several brake oils are mixed. After heating, there is air resistance, oil leakage from the brake master cylinder or sub cylinder, and air leakage from the air storage tank or pipeline interface. Improper operation will lead to failure of parts, and downhill will cause friction heat of brake pads, carbonization of brake hub and complete failure of braking function.

Change the brake oil regularly for 4WD rough terrain forklift

Brake oil is not actually oil. Its scientific name is synthetic brake fluid, which is referred to as brake oil for short. The main components are diethylene glycol + ether + anti-corrosion agent, detergent and other components. The corrosion requirements for the leather cup of the brake transmission system are particularly strict, because once the leather cup is aged and corroded, it will have a direct impact on the brake. Therefore, it cannot be replaced by other oil products.

It is the fluid used by the braking system to transmit force. Like engine oil, brake oil is also a kind of oil synthesized with various additives and has strong water absorption. Brake oil is also graded. According to the regulations of American Petroleum Association, brake oil is divided into dot3, DOT4 and dot5 1 these three levels.

does the rough terrain forklift need to replace break oil?

The volume of the brake fluid will change with the change of temperature. Therefore, the brake fluid storage tank is equipped with a vent hole. The air sucked in from the hole contains water or impurities, and the water will be absorbed or dissolved by the brake fluid. Therefore, the boiling point of the brake oil containing water will be reduced.

When the forklift is braked for a long time, the temperature of the braking system increases, the braking pipeline is easy to produce air resistance, and the air is compressed, resulting in the possibility of braking force decline or braking failure. Therefore, for your driving safety, the brake oil must be changed regularly.

Improper operation will lead to failure of parts, and downhill will cause friction heat of brake pads, carbonization of brake hub and complete failure of braking function.

Under what circumstances should the brake oil of 4WD off-road forklift be changed? If it is deteriorated, dirty or contains too much water, it should be replaced in case of these three conditions. Generally, it is required to replace 1000 hours, because the first time is the running in period. Later, it will take 500 hours to replace the gearbox every 2000 hours. Later, it will be replaced every 800 hours.

The part of 4WD off-road forklift adding brake oil is called "afterburner pump", which is generally hinged in the middle and sold to the upper part. Remove all the oil drain ports, then add new oil, and then install the oil drain port after the new oil flows out of the oil drain port.

Vegetable brake fluid shall be filled, and the liquid level shall be 15 ~ 20mm away from the filler. When the liquid is insufficient, it should be added. Do not mix the brake fluid with mineral oil, which will quickly damage the rubber components. Air mixed in the brake fluid will affect the braking performance. After cleaning the system, exhaust, remove the scale in the hydraulic pipeline and oil storage chamber, and fill up the brake fluid.

The brake oil of rough terrain forklift cannot enter the air. Once the air enters, it should be drained, otherwise the brake will fail and the braking effect will become worse. Because the pipeline enters the air, the air can be compressed, so the braking effect will become worse. This requires that there should be oil in the oil pot all the time. It can't be short of oil. Add it as you put it. There is a vent nozzle on the brake clamp, and the loose oil will flow out. If you feel slow, you can step on the brake. When all the oil is drained, add new brake oil and exhaust the air.

The oil drain port shall be tightened in time when the oil is not drained, and air shall not enter from the oil drain port. After changing the brake oil, how to check whether there is air? Without ignition, step on the brake hard, and then hold it. If you feel that the brake pedal is particularly hard and does not move down, it indicates that the oil change is very successful and there is no air. If you step on the brake pedal a little after a few steps, or feel that the brake pedal is not too hard and soft, you may have entered the air and need to exhaust again.
