How to Solve Air Leakage in Quick Release Valve?
2 Answers
The solution for air leakage in a quick release valve is: 1. Disassemble the upper and lower shells of the quick release valve; 2. Remove the damaged diaphragm and replace it with a new one. The quick release valve is used to adjust the ratio of input and output pressure, reducing the braking air pressure on the front axle during lower deceleration to prevent the front wheels from locking up during braking, thereby improving the overall braking performance of the vehicle. The quick release valve consists of an upper shell, diaphragm, sealing ring, and lower shell. The upper and lower shells are connected together with screws, with a sealing ring installed between them, and the diaphragm is placed in the inner cavity of the upper and lower shells. The lower arc surface of the upper shell serves as the deformation support surface for the diaphragm. There is a certain gap between the peripheral part of the diaphragm and the upper and lower shells, allowing it to move up and down.
I've personally experienced quick-release valve air leaks several times. The main reasons are usually aging seals or debris stuck inside the valve body, causing gradual air pressure leakage. The solution is simple: first check the pressure gauge - if the needle drops quickly, it confirms a leak. For DIY repair, remove the valve to clean it and use compressed air to blow out contaminants; if the seal is worn, simply replace it with a new one. I remember buying the replacement part at the store for just a few dozen dollars, then testing the pressure stability after installation. Never delay repairs as air leaks affect braking safety - it could be dangerous if brakes fail on the highway. Regular maintenance checks on component lifespan can prevent many such issues.
