DCA-800SSK — MAINTENANCE

Brakes

Trailer brakes should be inspected the first 200 miles of operation. This will allow the brake shoes and drums to seat properly. After the first 200 mile interval, inspect the brakes every 3,000 miles. If driving over rough terrain, inspect the brakes more frequently.

Air Brake System

Air brakes use compressed air to make the brakes function. Air brakes are a good and safe way of stopping large and heavy vehicles. There are many components that make up an air-brake system, such as the air compressor, air compressor governor, air storage tanks and air tank drains. These components need to be maintained by qualified and trained technicians.
