Review of Demco Trailer Brakes - Hydraulic Drum Brakes - 42029-28 Video

Brake Assemblies like the Hydraulic Brake Kit - Uni-Servo - Free Backing - 12" - Left/Right Hand Assemblies - 5.5K to 7K item #AKFBBRK-7 will have the description in the title that the brakes are free backing. We also offer the same size free…

I have attached a chart you can check out that describes the torque needed per wheel size, wheel stud size and material. For an 8-inch wheel with a 1/2-inch wheel stud the torque is 75 to 86 ft-lbs. For a 15 inch steel wheel with 1/2 inch wheel studs…

Though we do have the replacement bearings, races, and seals available for your Hadco 3109 hub (which I have listed below), the combination used will not have an equivalent replacement hub available, unfortunately. Replacement Trailer Hub Bearing…

The Kodiak Dacromet Disc Brake Conversion Kit, item #K2HR35D, would be a good choice for conversion to disc brakes on your boat trailer. We have not had the opportunity to do a video installation for the disc brake conversion yet, but I will go…

The nut on the spindle should be tightened until snug, with no side-to-side play in the hub and then backed off slightly, about maybe a 1/8 of a turn. If the spindle uses a castle nut and cotter pin or tang nut, tighten the nut finger tight until it…

Surge couplers for drum and disk brakes use different master cylinders that operate at different pressures, lower for drums and higher for discs. It is possible to swap out the master cylinder in a surge coupler to convert it from one type of…

I recommend using Grade 5 1/2" x 4" bolts to install the Demco Channel Tongue Trailer Coupler part #DM12717. These would allow for the full weight capacity of the coupler to be achieved. These can be picked up at most local hardware…

Hubs and drums that can be turned (machined) will have a specification on how much they can be turned cast into the metal of the drum somewhere. Otherwise it is at the brake shop's discretion. Drums do not have to be turned unless there is some…
