Installation and maintenance guidance

For professional workshop technicians and fleet managers, performing regular maintenance with high-quality repair kits prevents system failures. When installing, ensure all pneumatic ports are clean and that seals are seated correctly to prevent air leaks. Proper maintenance of the relay valve ensures consistent braking response across all axles.
