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.

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. 528032

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. 201637

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! 176202

Do you have a question about this Accessories and Part?


  • Can Disc Brake Actuator be Used with Trailer Drum Brakes
  • For 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...

  • Replacement Parts for Demco Drum Brake Surge Actuator Coupler 8605001
  • For 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.

  • 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.

  • 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...

  • 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.
