WebAir brakes are typically used on heavy trucks and buses. Typical operating pressure is approximately 100–120 psi or 690–830 kPa or 6.9–8.3 bar. A compressed-air-brake … WebTo release the spring brakes, normally about 414 kPa (60 psi) of air pressure must be supplied to the spring brake chamber to compress or “cage” the spring (See Diagram 4-1). If system pressure is below 414 kPa (60 psi ), the spring brakes start applying because there is no longer enough pressure to keep them released (See Diagram 4-2).
