Video Transcript for Review of Demco Brake Actuator - 5650
Today, we're going to take a look at the replacement master cylinder on the Demco brake actuators for drum brakes. Now, this replacement master cylinder assembly will fit the Demco trailer brake actuators for drum brakes. Trailer drum and disc brakes do require different PSI ratings, so that's why this part number can be used on drum brakes only. Drum brakes will usually need about a thousand psi pressure, whereas the disc brakes require 1600 PSI, so this master cylinder has the orifice size that'll produce 1,000 PSI pressure in your brake lines.The rubber boot end here on the master cylinder, this is what will connect to the actuator rod into brake actuator. The other end right here, it has the threads in it. This is where the orifice or the reverse solenoid will install for connection to the brake lines on your trailer.
What's nice about this master cylinder is a polymer construction, so there's no rust or corrosion. Does include everything shown here on the table. The master cylinder itself, the master cylinder cover, the gasket. Just install your gasket on the cover before you put it on there. Then you just line it up with the holes.
Does come with all the bolts and lock washers for them to install the cover down.And then the last piece it includes, the diaphragm style filler cap that you would just screw on there. Tighten it down, and then remove it to install your brake fluid. But that should do it for the review on the replacement master cylinder on the Demco brake actuator for drum brakes.

Replace the master cylinder on your Demco drum brake actuator. Fits all Demco drum brake actuators.by: Mike04/26/2024
Exact parts came as ordered and fit per fectly
by: Matthew G.04/23/2022
Master cylinder worked excellent. Sticker on lid said if your actuator case is threaded for fill cap don’t use the new lid that comes with the master cylinder. My threads were too rusted out to reuse so I used plasma cutter to enlarge opening to accommodate lid. This way no rusty threads and no rusty steel ceiling to contaminate fluid. 10 minutes well spent and looks better than new. This one won’t rust out either!

Exact part, works great

I just wanted to write back and tell y'all how great y'all are. I am enlisted in the Air Force here at Shaw AFB, so I don't have tons of money or lots of time. Your products came super-fast and was exactly what I needed. A little back ground on my situation, I have a 2004 boat trailer that has an A60 model Fulton folding Tongue that was discontinued in 2010. This made it impossible to find parts for it. I was able to use your website and the measurements listed to find replacements, the pictures also helped out a ton. By rebuilding my broken tongue i saved myself an easy $400-$600 to replace it. I received my order on Friday afternoon had the parts installed and was on my way to the lake in just over an hour. Perhaps my experience and success can help other people out with similar trailer tongues. i will definetly be using y'all for all my trailer needs.

All I know is that dealing with etrailer was a wonderful experience. I don't usually leave reviews but I'm making an exception here.
1. I thought it was simple to determine what parts I needed through their website.
2. After said parts were ordered they arrived quickly and adequately packaged.
3. New parts fit perfectly and I promptly received an email making sure things were all good in the hood.
Very refreshing transaction. I needed a new master cylinder and little shock absorber for my surge brake trailer, and etrailer did not disappoint. Parts were correct and replaced some jank az stuff that was previously installed. All good now!

Exactly what I was looking for to replace the dried up master cylinder for my boat trailer. Working great one year in.

When I disassembled the surge brake assembly I found it was too corroded to be rebuilt and I needed to buy the full surge brake coupler. The staff at etrailer were great to work with and helped me return the parts I bought and got the full assembly to me quickly.

Received the master cylinder in 4 days using standard shipping. The unit came with new bolts, lock washers, gasket, cover and cap. Bolted master cylinder in place and had the brakes (4) bled out in about a hour. I would recommend this master cylinder kit.

This product works as it should, no iss ues.
by: Korey04/07/2018
The price was the best I found and shipment was very timely. George even followed up on the day it was delivered to make sure all was fine.
I had just bought this trailer used and the etrailer site helped identify the proper replacement for a siezed master cylinder.
by: Tim L.02/26/2015
Have not yet installed this master cylinder. This is a very strong looking, plastic product. The original was cast iron. The plus to this? No rusting!
Also, this master cylinder also comes with a lid, if needed for your application, and the proper cap, whether the lid is used or not. And also, nuts, bolts, and washers, to complete the installation. These things are not pictured.
Blazing fast shipping!
by: James 10/28/2020
When I ordered was not sure of fitting . But did fit perfect and getting trailer back on the road. Have been very happy with quality and very fast service.

- Can Disc Brake Actuator be Used with Trailer Drum BrakesFor a disc brake actuator like the Demco # 8608611 to work with drum brakes you need to replace the master cylinder otherwise the pressure will blowout the wheel cylinders on your drum brake assemblies. If you were to have this specific actuator then you can use the Demco Actuator Replacement Master Cylinder for Drum Brakes # 5650 to make it compatible with drum brakes. If you have a different actuator let me know what it is. If we carry that brand then we likely have the master cylinder...
view full answer... - Replacement for Demco Master Cylinder 05680-C for Drum BrakesThe correct replacement for a Demco Master Cylinder 05680-C is the Replacement Master Cylinder part # 5650. I spoke with Demco to confirm this for you.

- Replacement Master Cylinder for Demco Drum Brake Actuator DM8101541The Titan Replacement Master Cylinder # T2336100042 is an exact replacement for their model Aero 7500 drum brake actuator. The correct Master Cylinder kit for your Demco drum brake actuator model # DM8101541 is part # 5650. This kit includes cylinder, lid, cap, and mounting hardware and it fits ALL drum brake actuators from Demco. The mounting hole pattern on this Demco part is 2 x 3-inches.
view full answer... - Replacement Master Cylinder 5650 for Demco Drum Brake ActuatorThe Demco replacement master cylinder # 5650 is designed to replace the master cylinder of the Demco Drum actuators like the part # DM72VR. It would install exactly like the one you removed would install. It comes with new cover, gasket, and cap. The cap will thread on just like the old one of your setup did.
view full answer... - Thread Size For The Demco Actuator Replacement Master Cylinder for Drum Brakes # 5650Hi Tim, I reached out to Demco and they stated that the thread size of the Demco Actuator Replacement Master Cylinder for Drum Brakes # 5650 is 3/8" -24 UNF. Demco lists that the brake line kit typically paired up with actuator would come with a .125” MPT X .188” inverted flare fitting (part 05679 in the product manual item list)
view full answer... - Replacement Inner Parts for Demco 12.5K Weld-On ActuatorThank you for all of the photos you sent in! I have some parts I believe will fit, but if you're able to find any exact part numbers on the actuator itself I will be able to provide more of a concrete selection of parts. It looks like your actuator is similar, if not the same, as the Demco Hydraulic Brake Actuator - Drum # DM8101222 which means the following replacement parts will fit: - Demco Actuator Replacement Master Cylinder for Drum Brakes # 5650 - Demco Actuator Replacement Break...

- Correct Replacement Actuator for 12.5K DA10 Demco Hydraulic Brake ActuatorTo replace the actuator on your Demco Hydraulic Brake Actuator # DM8101222 you need the part # 5650. Brake actuators naturally wear out over time so having a spare on hand is a great idea, especially if you use the trailer all the time and get a lot of reps in with the actuator.
view full answer... - Are Brake Actuating Coupler Master Cylinders Universal Fit?For a surge brake actuator, the master cylinders are not universal fit. There are different styles and there are different psi levels for disc brakes versus drum brakes. For instance the Master Cylinder for Titan Actuators - Disc Brakes # T4747100 cannot work in place of the Demco Actuator Replacement Master Cylinder for Drum Brakes # 5650 simply because it won't fit the mounting correctly or hold the same brake pressure. If the mounting locations and the pressure were ideal, then you...
view full answer... - Can Demco Replacement Master Cylinder for Hydraulic Disc Brakes be Used with Drum BrakesHydraulic drum brakes operate at around 1,000 psi where disc brakes are higher at about 1,500 psi. So the maser cylinder for disc brakes, part # 5672, is not the same as what you need. Instead you need the master cylinder for drum brakes, part # 5650.
view full answer... - Solution for Trailer Actuator that Needs Replacement Master CylinderI wish we could help but we don't have a solution for a replacement Atwood master cylinder. They got out of the coupler business a while back and none of the current master cylinder replacements would work. Best option will be a new coupler like the part # DX83FR.
view full answer... - How to Make Fulton A60 Swinging Coupler Compatible with Disc BrakesThank you for all of the info! I did some digging and found out that your older Fulton A60 swing away actuator was actually a UFP A60 actuator on a Fulton coupler hinge like part # FHDPW330300. I was able to speak with my contact at Dexter who said you can make your drum brake actuator compatible with disc brakes by changing out the master cylinder with kit # DX44FR. If you don't already have disc brakes I am linking our selection for you to filter through. If you'd like a recommendation...
view full answer... - Replacement Parts for Demco Drum Brake Surge Actuator Coupler 8605001For your Demco drum brake surge actuator # 8605001 you can use Master Cylinder kit # 5650. For replacement 10-inch drum brakes you can refer to the linked page which displays all 10-inch hydraulic drum brake assemblies. These are offered in capacities for 3500-lb and 3750-lb-rated axles. Individual replacement parts for Demco brakes are shown on the other linked page. If you also need new hubs you will want to note the bearings used in your existing hubs since new hubs must use the very...
view full answer... - Is the Titan Reverse Lockout Solenoid Compatible with Non-Metallic Master Cylinders?The Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 is compatible with a variety of master cylinders just like the Demco Reverse Lockout # DM11993. Either will work with a plastic master cylinder like the Demco # 5650. I recommend going with the Demco Solenoid because it is made to be a non-bypass solenoid so it seems to function a little better.
view full answer... - Replacement Brake Assemblies and Master Cylinder for 2002 Demco Kar Kaddy KK360SB Tow DollyThe replacement brake assemblies are # DMSB24429M for the left side and # DMSB24428M for the right. The replacement master cylinder is part # 5650.
view full answer... - Potential Replacement Master Cylinder For an Unknown Cylinder Marked 05680-0 or 05680-CI am wondering if the number you found on the old one is actually 05680-C and not 05680-0. The reason I say this is because there is a Demco master cylinder marked 05680-C. Which would make the Demco Actuator Replacement Master Cylinder # 5650 the correct replacement part. The Demco Actuator Replacement Master Cylinder # 5650 fits all Demco drum brake actuators and is likely what you have. If you feel that you have something else, you can submit some photos and I would be happy to take...
view full answer... - Does The Orifice for Demco Composite Master Cylinder Require Sealant Or Specific Torque Specs? The Orifice will tighten until it bottoms out inside the Master Cylinder # 5650 on the Actuator # DM72VR. The technician at Demco said there is not an exact torque figure they can give, just to tighten it until you feel the threads stop. The threads do not require any sealant to seal off the brake fluid from leaking.
view full answer... - How To Know Which Master Cylinder Will Be The Correct Replacement For A Surge ActuatorReplacement master cylinders will be brand specific, so they cannot be mixed and matched. As an example, the Titan master cylinder # T2374600 will only fit their Model 10 and Model 20, and the Demco master cylinder # 5650 will only fit their drum actuators. With that said, I was unable to find out which brand surge coupler is used on the Butler trailers, unfortunately. What you will need to do is contact Butler with your VIN, or trailer model number, and find out which was used. You will...
