Your trailer is fitted with hydraulic disc brakes, this is a very efficient braking system and if maintained correctly, will be trouble free and give long service.
Trailer brakes are also subject to much greater wear and tear than the tow vehicle brakes. Brake pads for example may require replacing on a regular basis depending on the trailer usage and loads carried.
The hand brake facility on this coupling is designed for use while manoeuvring the trailer. For permanent or long term parking the trailer wheels should be chocked.
Check the brake pads for wear on a regular basis. The pads should be replaced when the friction material has worn to less than 3mm thickness.
While there are no greasing points on the callipers, periodic lubrication of the two slide pins is required. This is best done when replacing the brake pads.
Where the brakes are fitted to a boat trailer, they must be hosed down with fresh water after immersion in salt water and it is recommended that they be given a full service each year.
Wheel bearings need to be checked for excessive play or noise on a regular basis, again especially on boat trailers. If the bearings are re-packed with fresh grease and adjusted from time to time they will give a long life. The grease seals also need to be checked and if necessary replaced.
Apart from greasing the main shaft, the override coupling needs little maintenance. Check for wear or damage regularly. On boat trailers, it is advisable to renew the brake fluid when servicing the callipers as it can become contaminated from moisture and cause internal rusting and seizure of the brake components.
