Electric Drum Brakes

Image_145Electric drum brakes are an extremely efficient and reliable braking system that require minimum maintenance.
They provide smooth efficient braking when operated by a vehicle mounted controller, which also provides the ability for the driver to manually apply the trailer brakes independent of the tow vehicle braking system.
They are available both with and without park brake actuation and when used on trailers over 2000 kg gross trailer mass (GTM) can be activated in a break away situation to conform with the Australian Design Rule requirements.
For extreme rough road use we recommend the AL-KO ”Off Road” version of electric brakes which are specifically modified to prolong brake componentry life in extreme rugged conditions.
