1. Primary Air Reservoir: The maximum allowable leakage rate for the primary air reservoir is typically specified in terms of cubic feet per minute (CFM) or liters per minute (L/min). Common values range from 2 to 5 CFM (5 to 14 L/min).
2. Secondary Air Reservoir: Similar to the primary air reservoir, the maximum leakage rate for the secondary air reservoir is usually expressed in CFM or L/min. It may have the same leakage limit as the primary reservoir or a slightly higher limit.
3. Brake Piping and Hoses: The maximum allowable leakage rate for the brake piping and hoses can vary depending on the component and its location in the system. Common leakage rates range from 1 to 3 CFM (3 to 8 L/min) per 1,000 feet (305 meters) of tubing or hose.
4. Air Compressor: The maximum leakage rate for the air compressor is typically specified as a percentage of the compressor's rated capacity. Allowable leakage rates may be in the range of 5% to 10%.
5. Air Dryer: The maximum leakage rate for the air dryer is often expressed in CFM or L/min and may be regulated to minimize moisture accumulation in the air system.
6. Service Brake Control Valve and Treadle Valve: Both the service brake control valve and treadle valve may have specific maximum leakage rates defined to ensure proper functioning of the braking system.
It's important to note that these maximum leakage rates are general guidelines and may vary based on regional regulations and vehicle specifications. To ensure compliance with applicable standards, refer to the relevant laws and regulations for the region where the vehicle operates.
