• 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...

• Comparing Free Backing and Duo Servo Hydraulic Brake Assemblies
  
• Good questions. The difference between free backing brakes like the # AKFBBRK-35-D and regular hydraulic drum brakes like # DMSB18794M-93M (referred to as duo or duel servo) is that the wheel brake cylinder has pistons on both sides of the regular/duo servo brakes instead of just the one side on the single servo free backing assemblies. The amount of braking doesn't change much between them, they just function differently yet under the same amount of hydraulic pressure. The duo servo...

• How to Find Replacement Drum Brake Assembly for Boat Trailer
  
• I can tell you exactly how to find compatible drum brake assemblies, though I took a look and could not find any type of reference to Dico 40511. To determine the brake assemblies that will fit your 2002 Escort boat trailer, you need to know your axle's weight capacity, your mounting flange bolt pattern and the inside diameter and depth of your drum. For example, Hydraulic Brake Kit # AKFBBRK-35-D are rated for 3,500 lb axles, have a 4-bolt mounting flange pattern and measure 10"...

• Difference Between Demco 10 inch Drum Hydraulic Brakes and etrailer.com Brand Brakes
  
• The big differences is basically pricing and brands. The part # AKFBBRK-35-D is a pair of Dacromet coated drum, hydraulic brakes that are free-backing. The part # 40716-15 is essentially the same thing buy made by Demco. The etrailer brand is going to cost less since it's our brand and there's not as much markup so it's the better deal. Now the part # 40716-15 is basically just the part # 40716 and # 40715. What doesn't make much sense though is the pricing difference. It would seem...

• Drum Brake Replacement Assemblies for Use with Titan Actuator
  
• Thanks for the photo and tape measure. That makes it fairly easy to help you get what you need. You need 3500 lb single servo brake assemblies. My recommendation is the Hydraulic Brake Kit - Dacromet - 10" - Left/Right Hand # AKFBBRK-35-D. The Dacromet is for increased corrosion resistance. You could alternatively use the Hydraulic Trailer Brake Kit # AKFBBRK-35 for a standard protection against corrosion or even upgrade to the Demco Galvanized set # 18788-87 for superior rust...

• Replacement Brakes and Bearings for 1993 Mastercraft Boat Trailer
  
• Before you choose brakes or bearings you should verify what's currently on your trailer. If it is a 3,500 pound axle part # AKEBRK-35-SA will likely fit if the trailer has electric drum brakes. Both sides are included and labeled. They're also self-adjusting so you only need to set the adjustment when you first install them and then leave them alone. You can measure the inner diameter of your drums to find if this fit or not. One of two bearing kits is likely what you need. You should...

• How To Determine If Boat Trailer has 10 Inch or 12 Inch Brake Assemblies
  
• When determining if you need 10 inch or 12 inch brake assemblies there are a couple of easy things to check to confirm the fit for your trailer. The first thing is you can measure the diameter of your hub. The second thing is you can look at the brake flange, if it has 4 bolts then it is 10 inch if it has 5 then it is 12 inch. Because you know you have a #84 spindle we can be confident that you have a 3,500 lb axle and you will need the 10 inch assemblies. I recommend the Hydraulic...

• Recommended Electric Lockout or Free Backing Brake Assemblies for Surge Brake Actuator
  
• The Titan Zinc-Plated Brake Actuator - Drum - 2-5/16" Ball - Bolt On - 8,000 lbs # T4079200 does not have a manual lock-out. Because of this, it is recommended to use an electric lockout like # T4748800 or free backing brakes so that you can back your trailer without activating the trailer brakes. You can use the Hydraulic Brake Kit - Uni-Servo - Free Backing # AKFBBRK-35-D for 10 inch assemblies or # AKFBBRK-7 for 12 inch assemblies.

• Replacement Wheel Cylinder for Uni-Servo Free Backing Brake Assemblies
  
• Your old Hydraulic Trailer Brake assembly # AKFBBRK-35L can use the Uni-Servo Wheel Cylinder # AKBRKR-H7-L-CR. These are corrosion resistant coated but not aluminum. Another option is to upgrade your entire assembly to the Hydraulic Brake Kit - Dacromet # AKFBBRK-35-D. This rust resistant coating will be on the backing plates, the springs are stainless steel, the cylinders are aluminum and they are designed for marine use.

• Free-Backing Trailer Brakes and Actuator Recommendation
  
• The pros and cons of electric lockout vs free backing brakes mostly comes down to the ease of installation in not having to wire up your actuator to brakes; I also prefer a system where it is easier to troubleshoot issues and has less "moving parts". For those reasons I recommend going with the free-backing brake system as opposed to going with an electric lockout actuator. For a new actuator I recommend the Demco Hydraulic # 8605001 . This is a great replacement for the Atwood 61101 and...

• Should Hydraulic Brakes be Replaced by Electric Brakes on Boat Trailer
  
• Since you have a boat trailer I recommend sticking with hydraulic brakes. This will not only be the easiest for you in order to make replacements but hydraulic brakes are the best for boat trailers because electricity and water don't mix particularly well. I'm not sure if you have hydraulic disc brakes or hydraulic drum brakes but I have added a link to our entire selection of disc brake assemblies such as the Kodiak # K2R35D along with our disc brake actuators such as the Titan # T47154107K.

• Recommendation For Brakes And Drums For WT20GAB Boat Trailer
  
• Based on the information you sent, it looks like your inner bearings are Item # L68149 and outer bearings are Item # L44649 which are common for 3,500 lb trailer axles. I did not see in part descriptions the bolt pattern of your wheels but the most common patterns are 5 on 4-1/2, 5 on 5-1/2, and 6 on 5-1/2. I will make recommendations for all based on these bearings sizes. I have attached an article on "how to measure bolt patterns" in case you need it. For a 5 on 4-1/2 bolt pattern,...

• Replacement Hub and Drums and Brakes for EZ Loader Boat Trailer
  
• If you are going to replace the axles and hubs then our hubs will come with the proper bearings. But in order to determine the correct bearings you would either need to replace the axles first and then tell me which axles you have so I can find hubs to match or if the axles are exactly the same as the old axles you could tell me the inner and outer bearing numbers stamped into the sides of the bearings. I checked the EZ loader site and did not see replacement axles as an option so I...

• Replacement Timbren Axle-Less System and Hydraulic Brake Assembly for 3,500 lb Axles on Boat Trailer
  
• I would love to help you upgrade your suspension components! I am guessing that you have 3,500 lb axles on your trailer but if you could verify that it would help me to make sure that I recommend the correct parts for you. Also, are you looking to add brakes to both axles or just keep them on one pair? You would get more braking power and less wear with brakes on all of the axles but if you only want them on one then that will also play into the parts.

• How to Determine Which Hydraulic Brakes to Use on a Trailer
  
• There are two different types of hydraulic brakes used on a trailer which are disc brakes and drum brakes. A drum brake has a small round drum in which the shoes inside the backing plate push up and out to slow the trailer whereas a disc brake assembly is composed of a circular round rotor and half moon shaped caliper which clamps down on the rotor to slow the trailer. I have attached a photo of both to give you a better understanding. The part number you provided "KH8444" was manufactured...

• Replacement Brake Assemblies and Brake Line for 3,500 Hydraulic Trailer Brakes
  
• Do you by chance have a 3,500 ALKO axle 8500? Or an 8,500 lb axle? I believe you'd have the 3,500 lb axle but wanted to be sure. For 3,500 assemblies you'd want the part # AKFBBRK-35-D as replacing all of the individual parts you mentioned would end up costing more and be more labor intensive. For a brake line kit then we have the part # 9504 which would fit and work well.

• How to Determine Which Drum Brakes to Get
  
• There are a few pieces of information that you will need to know when looking for replacement drum brakes. First of all you will need to know the weight capacity of your axle so you can choose drum brakes that will be able to safely stop your trailer. The brake mounting flange is another important thing to look at when looking for trailer brakes. The most common is a 4 bolt pattern, but there are 5 bolt patterns for trailers with a bigger weight capacity. You will also need to...

• Does Demco Hydraulic Drum Brake Actuator 8605001 Have a Reverse Lockout Feature
  
• Titan brake actuator # T4500600 does have a manual reverse lockout feature to let you back up the trailer without the brakes engaging. The lockout device can be seen in the linked review video at the 40-second mark. The other actuator coupler you mentioned, Demco coupler # 8605001 does NOT have any type of reverse lockout feature, neither a manual one like the Titan nor an electric type. Backing up a trailer that has a hydraulic surge coupler with no lockout will require free-backing...

• 3,500 lb Free-Back Hydraulic Brake Assembly Recommendation for Trailer
  
• For free backing, hydraulic drum brake assemblies that are 3,500 lb capacity we have assemblies that are 10 inch by 2-1/4 inch like the part # AKFBBRK-35-D which comes with assemblies for both sides of the trailer. We don't have anything that's 1-3/4 inch wide for a 3,500 lb axle.

• Difference Between Single, Dual and Free Backing Servo Brake Assemblies
  
• The biggest difference between the servo styles that you'll notice is between free backing plates and the others. The free-backing plates will allow your trailer to back up without having the brakes lock up. With surge brakes typically when you go to reverse the trailer it pressurizes the brake system which locks the wheels up. Free backing setups are designed to allow the pressure to build but not activate the shoes of the assembly so the trailer can back up. Some surge brake trailers...

• Proper Way to Adjust Brake Assemblies of Hydraulic Brake Kit # AKFBBRK-35-D
  
• The adjustment procedure you mentioned of tigthening the adjustement till you can't turn the wheel by hand and then backing off 10 clicks is the standard way to adjust brakes and would be the correct way to adjust the Hydraulic Brake Kit # AKFBBRK-35-D that you referenced. If you follow that procedure with these assemblies you'll be good. I also attached a video that shows how to adjust brakes as well. At about the 4:39 mark our installer begins adjusting the brakes.

• Can Mounting Studs be Removed from Hydraulic Brake Assemblies AKFBBRK-35-D
  
• The four mounting studs on Hydraulic Brake assemblies # AKFBBRK-35-D are not removable. These are press-fit for a permanent installation. For a similar brake without studs you can use Demco kit # 40716-15. These brakes are also free-backing galvanized finish left- and right-hand brakes for 3500-lbs axles.

• The 8-247 Dexter hub that you have is our part number # 84546UC3 which has drum dimensions of 10 inch diameter by 2-1/4 inches wide. That means that the Hydraulic Brake Assembly Set part # AKFBBRK-35-D that you mentioned will fit and work well. 45 to 50 lbs is the recommended torque rating for the 4 bolts that hold 10 inch brake assemblies like these.

First, you want to confirm the axles' rated capacity; this should be noted on a sticker or plate on the axles themselves. Based on the info you provided it may be that you have two 3500-lb axles. Your brakes and hubs must match the axle rating. Next you'll want to take note of the size of the current brakes. You need to confirm the diameter and depth. You also want to note their mounting...

• Recommendation For Replacement Brakes For 1997 MacGregor 26X Sailboat Trailer
  
• We will be glad to help but unfortunately there are all kinds of options and possibilities. The best way to find the right replacement brakes is to find the weight capacity of your axle (see attached picture), the size of your brake mounting flange (4-bolt pattern most common), and your drum diameter for drum brakes and rotor diameter for disc brakes. If your trailer has a 3,500-lb axle with drum brakes and a 4-bolt brake flange, I recommend something like the Hydraulic Brake Kit,...
