12-Inch Dexter Aftermarket Electric Brake Magnet
Upgrade your towing safety with our premium 12-inch Dexter aftermarket electric brake magnets, now on special! Engineered for seamless compatibility with all-electric brake systems, these heavy-duty magnets fit late-model Dexter and AL-KO setups, delivering reliable stopping power when you need it most.
Product Description
Designed for versatility, these late-model aftermarket magnets are fully interchangeable with standard AL-KO components. While primarily engineered for 12-inch systems, they can also be adapted to 10-inch brake assemblies that require enhanced stopping power. Don’t compromise on safety—upgrade your trailer’s braking efficiency today while our limited-time special pricing lasts.
Technical Specifications
- Current Draw: 3.4 Amps per magnet (Higher capacity than 10-inch 3.2A variants)
- Lead Wire Colour: Black leads (Genuine Dexter style)
- Compatibility: Fits all-electric brake systems; interchangeable with late-model Dexter and AL-KO backing plates
- System Cross-Over: 12-inch magnets can also be utilised on 10-inch brakes for specific setups
- Wiring Flexibility: Non-polarised leads (can be connected positively or negatively; internal polarity locks automatically once powered)
Key Features
- Genuine Capacity Guarantee: Unlike substandard 12-inch magnets sold with green leads (which are under-wound 10-inch magnets), our units feature full-spec copper winding for maximum braking force.
- Built-In Wear Indicators: Features four distinct wear-inspection holes at the 12, 3, 6, and 9 o’clock positions for foolproof maintenance tracking.
- Safe Failure Prevention: Engineered to clearly signal replacement needs before internal copper wiring becomes exposed to prevent open circuits.
Important Installation & Braking Tips
- Bedding-In Required: Brand new magnets feature a shiny factory finish. This surface must be scuffed up through initial light braking cycles to achieve 100% braking efficiency.
- Prevent Voltage Drop: Avoid running electric cables across your axle. Always route wiring directly down each chassis rail using correctly sized cables (e.g., 5.62mm for a 6m run down individual rails, or 7.5mm if routing inside the main trailer chassis) to prevent catastrophic voltage loss.
Frequently Asked Questions (FAQ)
How do I check my electric brake magnets for wear?
Inspect the face of the magnet for the four small warning holes located at the 12, 3, 6, and 9 o’clock positions. If these holes are worn flat, uneven, or are no longer visible, your magnet face has reached its wear limit. Replace the magnet immediately before the internal copper winding is exposed, creating an open circuit that renders your brakes inoperable.
What is the difference between Highway and Off-Road magnets?
Standard highway magnets use a steel-on-steel retaining clip that can rattle, causing premature wear on corrugated roads. Off-road magnets feature a durable plastic insert that absorbs vibrations and prevents the magnet arm from damaging the unit, ensuring they survive tens of thousands of miles on tough terrain. Note: Off-road variants use an installation rubber band that breaks on first use and relies on the return spring thereafter.
Are left-hand and right-hand side magnets interchangeable?
No, left-hand (passenger side) and right-hand (driver side) brake assemblies use specific orientations and are not interchangeable. Ensure you purchase the correct side for your backing plate, or consider upgrading the entire backing plate assembly if your current hardware is heavily worn.
Can I power my chassis-mounted brake controller from my trailer’s brake lights?
No. Standard vehicle brake light circuits provide only 21 watts of power and are meant strictly as control signals. Wiring a brake controller directly into the brake lights causes a significant voltage drop, reducing your brakes’ efficiency to less than 25%. All high-quality brake controllers (such as the Redarc, Tekonsha Primus or Prodigy) must be wired directly to a dedicated battery source.
How should I check my safety chains and breakaway system?
For tandem-wheel caravans, attach your safety chains to the tow vehicle and push the trailer back to the chains’ extreme limit. Check that the pin on your breakaway kit disengages before the chains reach full tension, ensuring emergency braking activates if a decoupling occurs.
