What are the causes of brake air pressure failure?
3 Answers
The causes of brake air pressure failure are as follows: 1. The air compressor belt is broken or severely slipping; 2. The air compressor is damaged; 3. Air leakage in the pipeline or joint between the air compressor and the air reservoir or between the air reservoir and the brake regulating valve; 4. The pull arm between the brake pedal and the brake regulating valve is disconnected; 5. The free travel of the brake pedal is too large, preventing the brake regulating valve from opening; 6. The push rod of the brake regulating valve is stuck; 7. Water enters the brake. Relevant information about braking is as follows: 1. Introduction: Refers to the action of stopping or reducing the speed of running locomotives, vehicles, other transportation tools, or machinery. 2. Principle: The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, install corresponding brake shoes, belts, or discs on the machine base, and generate braking torque under external force.
I remember once when I was on a long-distance drive, I encountered a brake air pressure failure, which almost scared me to death. Upon inspection, I found that the air compressor was severely worn out. After all, the compressor works too frequently, such as during frequent braking or when overloaded, it's prone to overheating or damage. It could also be a leak in the air storage tank, where the air slowly leaks out, causing insufficient system pressure. Another common issue is a clogged dryer; if water accumulates in the tank and isn't drained in time, water molecules can block the passage, preventing compressed air from entering. Valve problems can also be the culprit, like a faulty brake valve or safety valve that won't open or close properly. Aging pipes can also leak air, especially when joints loosen on bumpy roads. My advice is that once the pressure gauge shows an alarm, immediately slow down and pull over to check. Don't force it to keep driving, as brake failure is too dangerous. Regular maintenance like draining water and checking pipe seals can save a lot of trouble.
In my daily driving, I'm most concerned about air brake issues, usually caused by leaks or blockages in the air system. For example, if the sealing ring of the air reservoir ages and breaks, causing air leakage, the pressure won't build up; the compressor can also wear out and fail if it runs for too long or isn't maintained properly; if the dryer isn't cleaned well, accumulated water can obstruct airflow, affecting brake response. Don't forget sensor failures—if they inaccurately detect air pressure, the system may misjudge it as a malfunction. From my experience, these problems often occur in older vehicles or those that haven't been maintained regularly. For instance, neglecting to drain water monthly can lead to moisture buildup and potential hazards. Now, I've developed a habit: before starting the car, I always check if the dashboard's air pressure reading is normal. If it's abnormal, I stop in a safe place and wait for repairs. Safety comes first to avoid accidents due to brake failure in emergencies. Regular professional inspections of compressor components can also prevent many potential issues.
