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.

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!

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.

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.

All 3 parts that I ordered for my old trailer fit 100% perfectly. Paula was such a great help getting the right parts needed for my trailer.

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!

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.

  • Can Disc Brake Actuator be Used with Trailer Drum Brakes

  • How to Make Fulton A60 Swinging Coupler Compatible with Disc Brakes
    Thank 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...

  • Can Demco Replacement Master Cylinder for Hydraulic Disc Brakes be Used with Drum Brakes
    Hydraulic 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.

  • 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.

  • 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...

  • How To Know Which Master Cylinder Will Be The Correct Replacement For A Surge Actuator
    Replacement 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...
