Frequency of Servicing

This very much depends on type and frequency of usage, but an outline guide could be as follows:

  • Daily or before each journey - certain checks are essential for safety and are the responsibility of the trailer operator.
  • After the first 600 miles (1000 km) - essential for new trailers or if new brake linings and/or bowden cables are fitted.
  • Every 3000 miles (5000 km) - three monthly for commercial / industrial trailers intensive usage, either by mileage towed or type of application and including boat trailers that are immersed in water.
  • Every 6000 miles (10,000kms) - annually for caravans and leisure trailers.  Six monthly for commercial/industrial trailers - based on "average" use.
