Kalmar DCD: when do the handbooks change the parking brake linings after emergency braking?
After two emergency brakings in the DCD 180-250 technical handbook (1997 edition), as recorded at HIT SRL. The 2001 handbook of the DCD 280-500 gives one braking on its brake-system pages but two on its Meritor axle pages, as logged by the HIT SRL technical desk.
