Video Transcript for Demco Trailer Brakes DM60124 Review

Today we're going to be taking a look at the Demco trailer brake mounting flange. This brake flange mounts onto the end of a trailer axle to a provide secure attachment point for a brake assembly. This is designed for heavy duty agricultural applications. It's a sturdy steel construction. It's a weld on installation. A few measurements to go over with you real quick. There going to be four holes on this unit.

Those holes are separated on center by about 3 3/8" apart. I'll do that same measurement going this direction. It's going to measure the same, 3 3/8" apart on center. The plate dimensions measuring edge to edge. That's 4 1/2" by 4 1/2".

The thickness of this plate is 1/4", and then this hole here in the center. That gives us a diameter of 2 3/4". That's going to do it for today's look at the Demco trailer brake mounting flange.

  • Replacement Brake Mounting Flange for 3 Inch Diameter Mobile Home Axle Used on Trailer
    Mobile home axles are meant for a one-time use, so getting replacement parts for them is typically difficult to impossible, but assuming you already have hubs compatible with the existing spindles, we have the parts you'll need. A three inch axle would typically have a 6-7K capacity and use a # 4-44-1 brake mounting flange. The compatible brake assemblies would be part # 23-105-106 which are compatible with a 12 x 2 brake hub/drum. It's recommended that you use a welder who has experience...

  • Electric Drum Brake Assemblies for 3500-lb Axle with 5-on-4-1/2 Hubs

Be sure to select both left- and right-hand brake assemblies, such as # AKEBRK-35L-SA and # AKEBRK-35R-SA. If you also need hub/drums assemblies in the 5-on-4-1/2-inch wheel bolt pattern be sure to check your current hubs' bearings. New hubs must use the same inner and outer bearings in order to fit...

  • Parts Needed to Convert From Surge to Electric Brakes

The dimensions of this are extremely important because it will determine the brake assemblies that fit. The Demco Trailer Brake Mounting Flange # DM60124 has a 2-3/4" pilot hole and has a 4 on 4-13/16" bolt pattern. This is uncommon compared to Brake Mounting Flange # 4-35 which is for 2-3/8" round axles and has 4 bolt holes which are 2-7/8" apart on center, which is what you...
