Brake chambers of the right standard are a critical part of an effective brake system. Developed by the ATA Industry Technical Council, this Technical Advisory Procedure provides information on acceptable air brake chamber build standards, a brake chamber compliance table, and warnings against seeking to disassemble a spring brake chamber.
Brake chambers are also critical to vehicle compliance and the use of substandard parts may void compliance with the Australian Design Rules.
The use of substandard brake chambers could create an unstable vehicle combination by mixing different brake chamber sizes and brands, negatively affecting the brake balance.
