The Importance of a Properly Functioning Brake Magnet
Your trailerβs electric brake magnet is a critical component in the braking system. When you engage the brakes, an electrical current energizes the magnet, causing it to attract to the brake drumβs interior surface. This action forces the shoes outward against the drum, slowing the wheel rotation and ultimately bringing your trailer to a controlled stop. A worn or damaged magnet compromises this process, resulting in weaker braking performance, uneven wear on the brake shoes, and potential safety hazards on the road.
Why Replace Just the Magnet Instead of the Whole Assembly?
When braking performance declines, some owners consider replacing the entire brake assembly. While this can be effective, itβs often unnecessary if the issue is confined to a single component like the magnet. Replacing the magnet alone is typically more cost-effective, quicker, and simpler, allowing you to restore braking power without overhauling the entire system.
Reasons to Replace Just the Magnet
- Cost Savings: A magnet kit is more affordable than a complete assembly, minimizing repair expenses.
- Targeted Repair: If the rest of your brake components (shoes, springs, backing plate) are still in good shape, swapping out only the magnet preserves their lifespan.
- Less Downtime: Replacing the magnet is a more streamlined process, allowing you to get back on the road sooner.
- Maintain Original Parts: If you prefer to keep as many original parts intact as possible, replacing just the magnet is a more conservative approach.
How to Replace a Brake Magnet
Before you start: Always ensure your trailer is parked on level ground, wheels are chocked, and you have the necessary safety gear, such as gloves and eye protection. Consult your trailerβs manual for any specific guidance.
- Remove the Wheel and Hub/Drum: Begin by loosening the lug nuts, then use a jack and jack stands to lift and secure the trailer. Remove the wheel to expose the hub/drum assembly, then carefully slide the drum off the spindle to access the brake assembly.
- Locate the Magnet: Inside the brake assembly, youβll find the magnet seated at the bottom, typically held in place by a spring and retaining clip.
- Disconnect the Wiring: Gently unplug or disconnect the electrical connections leading to the magnet. Note which wires connect where, so you can reattach them correctly later.
- Remove the Old Magnet: Use pliers or a flat-head screwdriver to carefully remove the retaining clip and spring. Once free, slide the old magnet out and set it aside. Inspect the area for debris or damage.
- Clean the Assembly: Wipe away any dirt, brake dust, or rust inside the brake assembly. A clean environment ensures the new magnet functions at its best.
- Install the New Magnet: Position the new magnet in the same spot as the old one, making sure it sits properly. Insert the spring and retaining clip included in the kit to secure the magnet in place.
- Reconnect the Wiring: Attach the electrical leads as they were before, ensuring a solid, secure connection. Double-check that wires are not pinched or rubbing against moving parts.
- Reassemble the Hub/Drum and Wheel: Slide the drum back onto the spindle, followed by the wheel. Tighten the lug nuts to the manufacturerβs recommended torque specifications.
- Test the Brakes: Lower the trailer back to the ground and perform a low-speed test to ensure the brakes engage smoothly and evenly. Listen for unusual noises or vibrations, and confirm that the trailer stops as expected.
Installation Tips for Best Results
- Follow Manufacturerβs Guidelines: Each brake assembly may have slight variations. Always consult your trailerβs manual for specific instructions and torque settings.
- Inspect Other Components: While you have the assembly open, take the opportunity to inspect brake shoes, return springs, and the backing plate. Addressing issues early can prevent future headaches.
- Ensure Proper Wiring: Use proper connectors and insulation to keep your wiring intact, preventing shorts or intermittent braking issues.
- Lubricate Bearings if Needed: If youβve removed the hub/drum, consider inspecting and repacking the wheel bearings. This proactive step can enhance overall reliability and reduce rolling resistance.
Long-Term Maintenance and Care
Maintaining your trailerβs brakes goes beyond a single repair. Regular inspections and timely replacements keep your brakes responsive, safe, and ready for the load youβre hauling. Consider checking your brakes at least once a year or every 12,000 miles, whichever comes first. Inspect for unusual noise, uneven wear, or decreased stopping power. Address problems promptly to prolong the life of your braking system and prevent costly repairs down the line.
Conclusion
Investing in a 5200 lb – 7000 lb 12″ Replacement Magnet Kit is a smart, cost-effective way to maintain top-notch braking performance. By targeting the exact component that needs attention, you restore safe, predictable braking without overpaying for a full assembly replacement. With proper installation, routine inspections, and proactive maintenance, youβll enjoy a smoother towing experience and increased peace of mind on every journey.
