Is There a 12 Inch Brake Drum for a Dexter #84 Spindle Available?
Question:
Is their a 5 or 6 lug drum that will work on a #84 spindle, inner bearing L68149 with 12 inch electric brakes? This appears to be a Dexter moble home axle. This is on a triple axle boat trailer. Electric brake baker plate is welded to axle.

The #84 spindle from Dexter will limit the diameter of the brake drum to 10 inches, so this will not work with a 12 inch diameter brake, unfortunately. 12 inch brakes are generally fitted to 5,200 to 7,000 pound axles, which will typically have a much larger inner bearing. These will also use the 8 on 6 1/2 bolt pattern for the wheels.
The only way to keep a 5 or 6 lug drum on your current axles will be to cut off your current brakes and either weld or bolt on a 10 inch brake, like the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-468-469. If the mounting bracket for the brakes are not salvageable, you may need to weld on the Brake Mounting Flange # 4-35 to complete the install. It should be noted that this is designed to fit a 2 3/8 inch diameter round axle. You will then need either the Dexter # 84546UC3-EZ for a 5 on 4 1/2 bolt pattern, or the Dexter # 84546UC3-EZ for a 6 on 5 1/2 bolt pattern.
If you prefer to stay with the higher capacity 12 inch brakes, I suggest replacing the axles. The Dexter # 8327834-EB will include electric brakes, drums, and all bearings, seals, and caps needed. However, this will measure 95 inches from hub face to hub face and 80 inches from the center of one spring seat to the center of the other one. The included drums will also use an 8 on 6 1/2 bolt pattern, so you would need to replace your current wheels with something like the Kenda Karrier ST235/85R16 Radial Trailer Tire with 16" White Wheel - 8 on 6-1/2 - Load Range E # AM32739.
