Dexter K71-125-00 Magnet Kit for 12 x 2 Inch 7K and 10 x 2-1/4 Inch 4.4K Brakes, Black Wire, One Brake

The Dexter K71-125-00 Magnet Kit supplies the magnet and related hardware needed to service one Dexter 12 inch x 2 inch 7K electric brake or one Dexter 10 inch x 2 1/4 inch 4.4K electric brake. The kit is built for boat trailer axles using Dexter electric brake assemblies, where a worn or burned-out magnet is one of the most common reasons for weak, uneven, or failed brake engagement. Because trailer brake magnets wear down over time from friction against the brake drum, replacing the magnet along with its related components restores consistent electric braking performance without requiring a full brake assembly replacement.

This kit includes the magnet (after 7/16), the return spring, and the small hardware pieces that mount and retain them on the brake backing plate, along with an instruction sheet for installation. The kit is sized for one brake, so a trailer with brakes on both sides of an axle, or on multiple axles, will need one kit per brake being serviced.
