Semi trailers made before 1975 that are equipped with air brakes were designed during a time when air brake technology was becoming more prevalent in the trucking industry. These trailers often featured simpler designs and fewer safety regulations compared to modern standards. While they can still be functional, their age may require more frequent maintenance and inspections to ensure safety and compliance with current regulations. Additionally, retrofitting or upgrading components may be necessary to meet modern performance standards.
