Brakes and Brake Controllers
The braking system on your Dunbier trailer is generally a disc brake over-ride system, either in mechanical (cable operated) or hydraulic (fluid
operated). Hydraulic calipers must be sprayed with an anti-corrosion spray after use and fully serviced every 6 months. Trailers fitted with
Hydrastar braking system should cover the Hydrastar unit when standing for long periods to guard against the elements as they are not water
proof, never use spray directly with a hose or high pressure spray. Also it is good practice to change the hydraulic oil in the system every 18
months as condensation mixes with the hydraulic oil. For more information refer to your owners manual.
Your mechanical calipers and components are fully galvanized using stainless steel bushes and bolts. The system is reasonably easy to maintain
and providing you wash your calipers, discs and cable down straight after a days boating it will provide a long life. Mechanical brake cable generally
last some time, however at any sign of deterioration, the cable needs to be replaced. To adjust the tension on me-chanical brakes, boat, motor and
all equipment needs to be on the trailer. The cable can then be adjusted at the front pully Fig 1. or the adjustment bolt on the calliper Fig 2.
Remember to leave enough slack in the cable to allow for the flex in the trailer frame.
Trailers with a gross mass over two tonne are fitted with a Hydrastar Hydraulic Electric braking system and disc braked on all four wheels as shown
in Fig 3. This system needs an in car electronic electric brake controller to operate it correctly, owner supplied and fitted by an auto electrician. The
Hydrastar braking unit is mounted high over the coupling and must be kept clear of submersing and high pressure cleaners at all times. A
separate Hydrastar manual and wiring diagram comes with the trailer at time of delivery.
Brake controlles- Set brake controller application level approximately half way. Applying too much gain will overheat braking system and bearings.
This will affect your warranty.
Hydraulic brake systems require a higher level of maintenance than override mechanical systems, although brake lines are coated , the joiners and
hose fittings require regular spraying of protectant. Calipers and pads require yearly service and is suggested that they form part of the boat's
schedule yearly service , where callipers are stripped down, lubricated and new pads fitted if required.
