Oil tanker, water tank air brake and oil brake maintenance method

Various types of vehicles, such as oil tankers and water tankers, should be regularly maintained during long-term use. The brake system is particularly important, and it is hoped that the majority of car users will pay attention.

First, regularly check the thickness of brake pads or brake shoes

No matter what the brake system is, brakes (disk type) or brake shoes (drum type) will eventually complete the braking action. Therefore, check the thickness of the brake pads or brake shoes regularly. When it is found that its thickness is close to or less than the minimum thickness specified by the manufacturer, it should be replaced immediately. While inspecting the brake pads, check the wear of the brake discs or brake drums. If there is a dent on the contact surface, use a CD or drum to ensure that the contact area with the brake pads increases the braking force.

For cars braking on the oil line, check the fluid level of the brake fluid before leaving the car. If it is found that the oil level has dropped, check immediately whether there is a leak in the brake oil circuit. Brake fluids will fail due to the absorption of moisture from the air for a long time. The brake oil should be replaced regularly according to the manufacturer's regulations. It is best to change it once a year.

For the air brake system, pay attention to constantly drain water from the system and replace the dryer regularly. Water in the air system can corrode the pipe and affect the braking effect. In severe cases, it can even cause the brake system to malfunction. In addition, check the pump's working condition and the wear of the air pump belt. If problems are found, they must be promptly replaced.

Second, the brake replacement cycle

Normally, we will use the brake warning light on the instrument panel as the judgment basis for changing the brake shoe. However, this is the final bottom line. If it is only then, it is very dangerous. It should be reminded that although all vehicles have this type of warning system, some of them directly sense the thickness of the brake shoe, while others are completely worn out after the brake shoe has been completely wiped out. The brake fluid will therefore drop extremely and cause the warning light to illuminate. From. If the latter is the case, wait until the warning light is on, the brake pad metal base and the brake disc have been in the state of iron grinding, at this time, the bright iron will be seen near the edge of the tire in the tire. Therefore, every time you enter the factory, you must check whether the brake pads can be used, and replace the brake pads near the end of life, instead of just believing the warning lights.

Third, the brake system daily maintenance

Clean, high-quality brake fluid is basic for safety and braking system. You should always buy the best quality brake fluid on the market. If the brake fluid is dirty, let go and flush the entire system, then fill the main cylinder with new fluid. Brake fluid should not be reused. All brake fluid released from the system should be discarded. In the maintenance of braking systems, it is of utmost importance to regularly check the brake fluid level. At least once a month check, more often than not.

Inhalation of asbestos dust is very harmful to your health. Removing dirt from the brake system with a dry brush or compressed air can cause dust, which can easily damage health because it contains asbestos fibers. Dust and dirt should be treated with an asbestos-free vacuum cleaner, and dust protection should be used. If there is no vacuum cleaner, it should be in a well-ventilated place and equipped with a certified anti-virus respirator when servicing the brake assembly.

Before checking the brakes, carefully clean the dirt on the main tank to prevent any dirt from falling into the tank. Remove the fasteners (usually the pins) and the lid. For uncalibrated cylinders, keep the liquid level 6 mm from the top of the cylinder. If there is a scale, just keep the liquid level higher than the scale. If the master cylinder needs to be refueled, add a heavy duty brake fluid that meets the dot3 or 4 specifications. Be careful not to put the brake fluid on the paint, because it is very corrosive and can damage the finish.
