Video Transcript for Titan Replacement Master Cylinder Assembly Installation

Today on our boat trailer, we'll be installing the Titan Master Cylinder Assembly, part number T4749501042. We're also going to be using a reverse lockout solenoid for hydraulic brake actuators. It is part number DM11993. Here's our master cylinder for reverse lockout solenoid already screwed into it. Your master cylinder will have a fitting like this in the back of it. You just unscrew that and you can screw your solenoid in for the reverse lockout. I will show you how to install the master cylinder real quick.

We will just slide it into the tongue of our trailer like so, making sure the push rod slides into the channel of the tongue and then we'll grab our bolts here, there are 2 on either side that it bolts to. We'll have to push in on our master cylinder a little bit in order to line up the bolt holes. Now we have these started on this side, we will do the other side the same way. Once we have all 4 bolts started, we can tighten them down. Now we can take our brake line and secure it into our lockout solenoid here. We'll tuck out the excess brake hose underneath the trailer in the channel.

We will tighten up our fitting going into the lockout solenoid for our long brake hose going back to our T fitting and we will secure our access down. We can fill our master cylinder with some fresh, clean brake fluid from an unopened container. Fill it up and re-secure our cap like so. We can open up the brake bleeder on the passenger side, because it is the furthest from the master cylinder. I want to use the top one, you always use the top brake bleeder.

I will open this up a little bit using a 7/16 wrench. Now we can start bleeding our brakes. You can take your safety chain here and give you a place to rest a 2 by 4 or metal pipe along and you can push the tongue of the trailer back into the master cylinder and we can begin the bleeding process. Pushing back on the tongue like so, and I will keep on doing this process until we have no air bubbles coming out of the bleeder screw on either caliper. Now that we've had a steady stream of fluid coming out of the passenger side, we have a screw here on the top, we'll do the same on the drivers side and once we have a steady stream of fluid coming out of that one as well, we will top off our brake fluid in the master cylinder and we will check the system for any leaks that any of the connection points where our hoses meet. If not leaks are found, our hydraulic portion of the brake system is done, so we can to ahead and put our wheels back on now at this point and time. Now that we have completely bled our brakes and checked or any leaks, we can actually hook up our reverse lockout solenoid. These wires can now block out solenoid.

We will ground one of them to the trailer frame and the one will go to the reverse wire signal from our trailer input on the electrical connector. I will take one of the wires, strip off about 1/4 inch or so and then we will take a ring terminal here and crimp it on and we will use this one as our ground wire and we'll ground it to the frame of the trailer. With that we will use a self tapping screw right here and we'll just find a place in the frame to ground it to. We got our self tapping screw and screw gun. We'll take our other wire here and hook up the reverse input of our trailer. Strip off 1/4 inch, take a weather proof butt connector here insert it and we'll crimp it down as well. The other end will go to our bi-pole or our 7 pole, whichever one we are using. This will be the input for the reverse signal. We're going to convert our trailer to a 5 hole signal here by flat. This is for bigger boat trailers. The 5 pole flat connector that we are using here for either installation of the trailer wiring is 20017. There is a blue wire here which is the signal for reverse for your trailer brake lockout solenoid. We will strip off 1/4 inch of this blue wire here and we will install it into our butt connector here that goes to our solenoid. We will crimp it into place. We can hook up the rest of our wires to where they go based upon our connection here. We will take our old connection here and cut off these zip ties to separate our wires so we can access them a little bit easier. I'm going to start with our green wire, strip it back about 1/4 of an inch. We are measuring off where we need to trim back our green wire, right about there we will cut the excess off of our green wire, strip back another 1/4 of an inch and install our butt connectors. Now we will take the brown wire for our right side and we'll do that one next and then we will do the same for the other wires. With all of our electrical connections made now, we can use our heat source, seal our heat shrink butt connectors up. To help tidy up our wires, I'm going to take some electrical tape here and wrap around our wires, just so we don't have a lot hanging down and this will make a nice clean install. Now that we've done that, we can actually go hook it up to our truck and go down to the lake and enjoy our boat. That completes the installation of the Titan Master Cylinder Assembly, part number T4749501042.

I recently purchased a master cylinder assy for my boat trailer. After receiving the part I noticed there was not a brass adapter fitting in the back of the master cylinder as shown in the picture and clearly stated in the product description that this part was included. I removed the brass brake line fitting from the old part but it was the wrong size. I called etrailer and spoke to Carol. It was a weekend so I was surprised someone answered the phone. Bottom line is Carol took care of me and within a few days the part showed up and the master cylinder is now alive and well where it needs to be....on my trailer. Thanks Carol....GREAT JOB 604730

As always the part came in a reasonably short time "FREE SHIPPING" and again as always just what I needed, I have bought just the master cylinder in the past from my local trailer parts dealer and it didn't come with a new boot or a new cap...etc. and by the time I removed, cleaned and transferred the spring assembly and mounting brackets I had way to much time invested in my project. Today it took not even 5 min to install this part to my hitch and it fit perfect. I truly believe that etrailer.com is the only way to go for any of your trailer needs.

Thank you to all at e-trailer and thank you for the master cylinder I ordered and a nice thank you to Wayne for calling back a message to me. I used a reverse bleeder and pushed the fluid from the calipers and got rid of the dirty fluid just before master then blead the master and soon I had four wheels braking nicely. Thanks to all of you for making our vacation safer towing the boat. Richard 288724

Do you have a question about this Accessories and Part?


  • How to Modify Drum Brake Actuator Coupler for Use with Disc Brakes
  • Brake fluid pressure requirements for disc and drum brakes are too different to allow use of a disc actuator on drum brakes. Disc brakes typically need 1500-psi while drums need about 1000-psi. Brake proportioning valves do exist but we do not sell them. From a safety standpoint we do not like to recommend using a device like that. We always recommend using the appropriate actuator for the type of brakes on the trailer. Some actuators can take either drum-brake-pressure master cylinders...

  • Can a Titan Model 10 Actuator for Drum Brakes be Used with Disc Brakes
  • The part # T2478100 is indeed designed for use on trailers with drum brakes. The master cylinder of the actuator is designed for lower pressure drum brakes. What you can do is swap out the master cylinder of the actuator with the part # T4749501042 and it would be compatible with disc brakes.

  • Replacement Master Cylinder For Tandem Axle Boat trailer With 10,000 Lb Capacity
  • To replace the master cylinder on your tandem boat trailer you will need to know a couple of things. Since there can be no guarantee of a fit you will need to let me know the make of the master cylinder you currently have. Also, are you using disc or drum brakes on you trailer. You would not want to use a disc brake master cylinder with drum brakes because the psi rating is much higher for disc brakes. Using it on drum brakes can lead to damage to the wheel cylinders and very aggressive...

  • Will the Replacement Master Cylinder Assembly # T4749501042 Work on a Cronkhite Trailer
  • If the master cylinder from your brake actuator on your Cronkhite trailer has the numbers 23744 stamped on the side, then it probably uses a Titan model 10 or model 20 brake actuator. To ensure that you select the correct replacement master cylinder assembly, we will need to know if your trailer has disc brakes or drum brakes. If your trailer has disc brakes, then you will need the replacement master cylinder assembly, # T4749501042, that you referenced. If your trailer has drum brakes,...

  • Troubleshooting Titan Surge Disc Brake Actuator
  • It could be that your reverse lockout solenoid needs replacement. Part # T4748800 is the replacement part. But I suspect your master cylinder is the cause for the brakes staying locked up until you release the pressure from the bleed valve on one of the calipers. You can check your master cylinder to see if the piston returns to its normal position after you manually compress it. If not you will want to replace it with part # T4747100 which fits the model 10 disc actuator. For the same...

  • Can Titan Model 10 Actuator be Converted to Disk Brakes from Drum
  • Since you have a Titan Model 10 actuator for drum brakes you can convert them to disc. You can swap out the master cylinder of your Titan model 10 actuator to the part # T4749501042 and you would have a disc brake setup. Now to determine the rest of the parts needed requires a bit more information. We need to find the hubs that will fit the spindles of your trailer.

  • Is Titan 10,000 Pound Brake Actuator Compatible with Kodiak Stainless Steel Disc Brakes
  • For your brake actuator to be compatible with your Kodiak stainless steel brakes, the actuator will need to be a disc brake actuator. Kodiak only makes disc brakes. If your actuator is a drum brake actuator, not a disc brake actuator, it will not be compatible with the Kodiak disc brakes. If your Titan actuator is made for disc brakes, it will work well with your Kodiak brakes.

  • Replacement Master Cylinder for Titan Model 10 or Model 20 Actuator
  • The easiest way would be to know the part number, but if you need a master cylinder replacement you actually don't need to know if your Titan actuator is a Model 10 or Model 20 because the master cylinder replacements we carry can be used for either.

  • Replacing the Master Cylinder on a Model 10 Titan Actuator with Rear Access Blocked
  • Yes, you can replace the master cylinder of the Titan 10 Actuator by removing the inter slide. Removing all the parts in front of the master cylinder will be quite tedious. It may be easier to cut off the jack and replace it with a bolt on frame jack like # F1413140334. This will allow you access to the rear of the actuator to replace the master cylinder for disc brakes with # T4747100 or if you wanted one with the frame assembly # T4749501042.

  • Troubleshooting Master Cylinder T4749501042 Not Releasing Fluid When Installed on My Trailer
  • Sounds like there could be a few things happening. Your coupler could not be depressing the piston of the master cylinder, your coupler has an electric lockout, or the master cylinder is bad. Let's start with checking the coupler to make sure its getting enough pressure to the master cylinder piston, I recommend taking your safety chains from the trailer around the coupler and hook them up closely to the hitch of your vehicle, this way you will be able to use about a 4 foot 2x4 board...

  • Will Titan Master Cylinder Assembly Fit Dico Hydraulic Brake Actuator
  • If your Dico Actuator is a model 10 or 20 and is designed for disc brakes then part # T4749501042 will work well for you. If you have drum brakes, and have model 10 or 20, then the replacement master cylinder you need is part # T2374600.

  • Yes, you do need to change the master cylinder on your actuator if you are converting from drum brakes to disc brakes.

  • We carry several replacement parts for the Model 10 actuators, but no we do not carry kits that have them all together. Some of the more common parts we sell would be the part # T2374600 master cylinder for drum brakes or part # T4749501042 for disc. For a replacement shock part # T1242600. For the replacement chain to go along with the # T1054100 you would want the part # T0776800.

  • Do Brake Actuator Master Cylinders Have Weight Capacities
  • The weight capacity is determined by the actuating coupler itself, and not just the master cylinder. Master cylinders are specific to the actuator models. Most of the Model 10 couplers have a weight capacity of 12500 lbs. If you are looking for a replacement master cylinder for your Model 10 actuator, we do offer the replacement master cylinder for drum brakes, part # T2374400. We also offer a replacement master cylinder for a disc brake Model 10 actuator. That part number is # T4749501042....

Unfortunately, it isn't easy to give you anything tangible without more information. The cost of your tires, bearings, and master cylinder will depend on what is actually on your trailer.

  • Troubleshooting Disc Brake Performance on a 12,000lb Boat Trailer
  • There are a few things that can cause your brakes to not lock up, but you should be able to get them to lock when braking hard. Some of the most common causes are: There is air or grime in the lines The brake pads are dirty or have grease on them The disc brakes are brand new and haven't had a chance to seat properly into the brake pad or If the disc brakes were a recent upgrade and not original to the trailer it is possible that the brake actuator still has a drum master cylinder...
