• Comparing Different Hydraulic Trailer Brakes for Boat Trailer
  
• Essentially yes, all of them will work for your trailer assuming you have 3,500 pound axles and a 4 bolt mounting flange. However, there are some differences between the brake assemblies you mentioned. The # AKFBBRK-35 are free-backing brakes, meaning they will not engage when reversing with your trailer. If your trailer has a reverse lockout on it then this feature is not necessary. They're coated with an e-coat used for corrosion resistance. The Demco brakes # 40716-15 are galvanized...

• Spring Seats and Nut Coupling Available Separately for Over-Under Conversion Kit

• Does the Demco Hydraulic Drum Brake Assembly Come With the Drum?
  
• I do have a solution for you but the answer to your question is no, the Demco Hydraulic Drum 3,500 lbs - 10" Brake Assembly # DMSB24429M is just the brake assembly without the drum. Keep in mind that when selecting a brake assembly and hubs that you make sure they will have the same weight capacity that your axle has. You will want to make sure that whichever brake assembly you choose that you get the Right Hand side as well, in this case it would be the Hydraulic Drum Brake part # DMSB24428M. I...

This is a standard size for 10x2-1/4 inch brakes. The outer diameter of the nuts is larger of course so it is not surprising that the wrench you used was larger.

• Adding Electric Drum Brakes to a Scamp Camper Trailer
  
• Setting up a trailer with electric drum brakes is going to be the easier and most cost effective way of adding brakes to your Scamp trailer. Since the trailer already has the mounting flanges that will limit the amount of parts and work that will need to be done. Starting with the hub and drum assemblies since your bearings are both L44649 and you have an EZ Lube style axle you would need # 8-257-5UC3-EZ with the 5 on 4-1/2 bolt pattern. They are designed for 2,000 pound axles but will...

• Replacement Hub/ Drums, Brake Assemblies and Tires for 2003 Trail-Lite Travel Trailer
  
• The Hub and Drum assembly you referenced, part # 84546UC3 has the same casting number on it, so it is most likely the correct replacement for you. I would recommend looking at your existing bearings to confirm a match. If the existing bearings you have are # L68149 inner and # L44649 outer, these are the correct replacements. For electric brake assemblies, use # 23-26 for the left side, and # 23-27 for the right. The mounting nuts, # 6-17 and lock washers, # 5-8 are not included....

• Parts Needed to Install Electric Trailer Brakes on a Pop-Up Camper
  
• You have compatible hub and brake assemblies selected. The brake assemblies, # 23-48 right hand, and # 23-47 left hand, will mount to a 4 bolt flange that has bolt holes 2-7/8 inches apart on center. You will need to make sure your existing bearings and seal match the bearings and seal in the hub and drum you selected, # 8-257-5UC3-EZ, and that the wheel bolt pattern, 5 on 4-1/2 inches, matches also. The trailer hub and drum # 8-257-5UC3-EZ is designed for use on an EZ lube axle with grease...

• Parts Needed to Add Electric Brakes to a Utility Trailer with a 3500 Lbs Axle and Brake Flanges
  
• You will need several items to add electric brakes to your Carry-On Utility trailer. Starting with the trailer you will need a hub and drum that matches the bearings and seal on your trailer spindle and your wheel bolt pattern. The only way to be sure is to check the bearing part numbers and seal part number, but with a 3,500 lbs Dexter axle that has brake mounting flanges you will most likely have the # L44649 Outer and # L68149 inner bearings and # 58846 seal. If these are the correct...

Your existing bearings and grease seals should have reference numbers stamped on them, make sure the numbers on the existing parts match those of the replacements.

• Converting 3500 lb Axle from Idler Hubs to Electric Brakes
  
• The brake mounting flanges, whether they be 4 or 5 bolt, have a standard hole spacing to fit their appropriate brake assembly. No worries about the brake assembly matching with the existing one on your axle. A 3500 lb axle like what you have will use a 4 bolt flange. You will need to get the numbers that are stamped on your existing bearings, in order to confirm the fit of the # 84557UC3. Your current bearings will need to match the bearings of the replacement hub. The # 84557UC3 uses...

• Electric Brake Install 2000 Coleman Sedona

We sell the nuts individually as part # 6-17 and the lock washer as part # 5-8. You'll need four of each per brake assembly.

• Adding Electric Brakes to a Trailer with Inner and Outer Bearing L44649 and 13 Inch Wheels
  
• To start, the trailer is going to need hub and drum assemblies. Based on the bearing numbers there are several options available. If your 13 inch wheels have 4 bolt holes then you would need 2 of assembly # 8-173-16UC3. If the wheels have 5 bolt holes then you would need 2 of assembly # 8-257-5UC3. For electric brakes for either of these assemblies you would need # 23-48 for the right side and # 23-47 for the left side. You will also need 8 of nut # 6-17 and 8 of lock washer # 5-8. And...

• Trailer Brakes Recommendations for a 3,500 lbs Boat Trailer Axle
  
• You have the standard brake mounting flanges on your axle. If you want to get really technical, the bolt holes should actually measure about 1/16 larger than 2-3/4. That is the standard dimension for 3,500 lb axles. If you are looking for hydraulic brake assemblies, I strongly recommend the 10 Inch Free-Backing Dacromet Brake Assemblies, # AKFBBRK-35L-D for the left hand and # AKFBBRK-35R-D for the right hand. Free-backing brakes will not lock up when you are backing up the trailer...

• Parts Needed to Install Brakes on a Tandem Trailer with Hayes 3,500 lb Axles
  
• You are correct, the # 84 spindle parts do interchange to 3,500 lb Hayes axles, as long as it is not a boat trailer axle, so you can use the Dexter parts on these axles. The spindle and hub parts for this application are standard parts that are still used in production, so they should be around for a long time to come. Of course keeping a record of the parts you use will help with replacement in the future. You could always return to Hayes parts in the future, the only thing to keep...

• Parts Needed to Add Electric Trailer Brakes to Pop-Up Camper
  
• The Dexter 8-91 hub would have a 4 lug on 4 inch bolt circle and would use L44649 bearings, so I'd recommend checking to see if your existing bearings have the same reference number. I've linked you to an FAQ article that shows exactly what you'll need to add electric brakes to your pop-up camper. Your existing axle would need to have brake mounting flanges mounted on each end behind where the hub would sit. The flanges provide a spot for the brake assemblies to bolt in place. If you...

• Brake Assembly for Use with Dexter Galvanized Trailer Hub and Drum # 8-247-50UC3
  
• Since your boat and trailer will be used in salt water a galvanized hub/drum is a good idea to give you some corrosion protection.

These are suitable for a 3500-lb axle and a 4-on-4-inch brake flange mounting pattern. I have linked an installation video for your reference.

• Which Hub Drums and Brake Assemblies for 3500lb Axle on Utility Trailer
  
• It sounds like you have a pretty good handle on what you need. If your existing hubs use the 5 lug on 4-1/2 inch bolt circle, and the surface of your spindle where the grease seal rides is around 1.719 inches, the # AKHD-545-35-K is the proper hub/drum. You can go with standard brake assemblies, like # AKEBRK-35L for the left side and # AKEBRK-35R for the right. However, I'd recommend going with self adjusting assemblies like part # AKEBRK-35R-SA or the right sided and # AKEBRK-35L-SA...

• Hardware for Attaching Brake Flanges of Titan Disk Brake Kit # T4843800
  
• The hardware needed for securing the brake flanges of the Titan Disk Brake Kit # T4843800 are not included as typically the axle has them already. If not we have the part # 7-75 which would be the correct bolt size. For a lockwasher you'd want part # 5-8 and if you do need a nut for the backside of the bolt part # 6-17. With the P3 you would not need to use the adapter part # T4846000. It is designed to work with the EOH brakes without the need for an adapter.

• What is Brake mounting Bolt # 7-75 Made Of
  
• The brake mounting bolt # 7-75 is just made of steel. If you can find a galvanized or stainless bolt with the same threads (bolt size is 7/16-20 and length is 1-1/4 inches) you could use it.
