12-inch electric brake magnets are suited to all caravan electric brake systems except for older round magnet brake systems.

How to check magnet wear

• Check the four small holes on top of the magnet.
• These holes are warning indicators that display magnet wear.
• Extreme magnets wear if there are no holes or less than four holes.
• When the face of the magnet hole has worn, then it is time to replace the magnet.

Key Features

• Wear holes are at 3 pm, 6 pm, 9 pm and 12.
• Magnets draw approximately 3.2 amps each
• Wires can be connected either positive or negative.

Once worn, copper begins to become exposed. Subsequently, an open electric circuit will render the brakes inoperable.

TIP:

• Bed new magnets into position to achieve 100% braking efficiency.
• The magnet face is a shiny finish.
• This finish needs to be scuffed up during the initial stages of breaking before your magnets become 100% effective.
