Video Transcript for Review of Dexter Replacement Master Cylinder Assembly Dexter Model 10 20 Disc - T4749501042
Hi everybody, Andy here with etrailer.com, and today we're gonna take a brief look at this replacement master cylinder assembly. This is going to replace the master cylinder assembly for your Dexter Model 10 or Model 20 brake actuators, and this is going to work with disc brake applications only. And for drum brake applications, I am including our item number for the master cylinder assembly that will work for drum brake applications. You can just take that item number and put it in a search field of our website, and it will take you to that master cylinder assembly. And this includes the master cylinder, obviously, and everything needed to install in your actuator. You have your brass connector, and then you have your right hand cylinder mounting brackets and left hand cylinder mounting brackets.
And then you're going to get two of the 3/8 of an inch hex bolts, and then two 3/8 of an inch hex nuts with two 3/8 of an inch lock washers. And then of course the filler cap here. And on our cap it says here use only DOT type 3 brake fluid, just so you're aware of that. And then the mounting holes, center to center, we are sitting right at 4 and 3/4 inches center to center. Let me line that up there for you a little bit better.
There you go. 4 and 3/4 inches on those mounting holes center to center. Well, that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy.
Thank you for joining me.

Always an easy transaction
by: Timothy02/13/2019
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
by: Jim Andersen11/28/2016
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.

Did a complete rebuild of trailer brakes that were just blocks of rust. Couldn’t have done it without the etrailer videos and OEM replacement parts. The Titan actuator fit perfectly, works great.
by: Andy06/18/2017
Exact fit. Works beautifully as it should. Brand new is a wonderful thing on an old crusty trailer. Great price...speedy shipping....can you ask for more?
Highly recommended. Thanks etrailer
by: Richard A. 08/28/2016
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.

It was a replacement brake cylinder. Installed easily. Brakes now work as good as new. There have been no issues.
by: Nathan12/04/2021
Wow, the packaging was the worst I have ever seen... Were they trying to be funny? A master cylinder just bouncing around in a box with the 2 grease seals, nothing protected with packaging, just rattling around in there. Lucky for me the parts in the box, and poking through the side of the box when it arriver were all ok. Glad I was in a good mood, I found it funny this time.

Delivered on time, should pack better, but works perfect
by: Jim G.10/05/2016
The product pictured matched my old unit exactly. Received item in a reasonable time. Was able to install the new unit with no problems. I need to complete reworking the rest of the brake system before I can test but so far everything looks great.
by: Frank08/05/2019
I am very happy with my order Everything was correct and I received it in a very good timely manner. Thank you Lisa for getting the master cylinder and selinoid to me that quick It was ordered late Thursday and got it on Monday and back together and ready to go fishing. Again thanks

- Replacement Master Cylinder for Titan Model 10 ActuatorWhat is the brand and model of actuator?
view full answer... - Disc Master Cylinder and Reverse Lock Out Recommendation for Titan Model 20 ActuatorTo convert your Model 20 actuator to work with disc brakes only requires the master cylinder to be changed to the part # T4749501042. Then for an electric reverse lock out solenoid all you need is the part # T4748800 and your set.
view full answer... - Orifice Connector For Old Style Titan T20What you have in the photo is the older 068-351-00 orifice connector with your Titan T20. Those connectors are obsolete and are not even available through Titan (now Dexter) any longer. The only other option is to replace the master cylinder completely in the older T20 using the part # T4749501042 if you have disc brakes or part # T2374600 for drum brakes which come with the a new connector.

- Can a Titan Model 10 Actuator for Drum Brakes be Converted to Disc BrakesYes, you can swap out the master cylinder of your Titan model 10 actuator to the part # T4749501042 that you referenced so that it would operate a set of disc trailer brakes.
view full answer... - Titan 20k Surg-o-matic Coupler Disc Brake ConversionFor your 20K coupler, the Replacement Master Cylinder Assembly for Titan Model 10 and Model 20 Brake Actuators - Disc # T4749501042 is the fit for your Surg-o-matic coupler.
view full answer... - Does The Master Cylinder Assembly Need Removed Before Welding Actuator # T4830300? I do recommend removing the Master Cylinder Assembly # T4749501042 from the Dexter Brake Actuator # T4830300 before welding it in place. This will ensure you do not melt the inner boot on the front of the master cylinder. This assembly is only held in place by 4 bolts and removes easily.
view full answer... - How to Modify Drum Brake Actuator Coupler for Use with Disc BrakesBrake 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...
view full answer... - Can Master Cylinder be Accessed From Front Of Titan/Dexter Model 10 Disc Brake ActuatorNo, you'll need to access the master cylinder from the rear of your Titan (now Dexter) Model 10 disc brake actuator. To replace it use the Replacement Master Cylinder Assembly # T4749501042, and I have linked a video below which shows how to do so, and accessing/installing it from the rear of the actuator.
view full answer... - Replacement Master Cylinder For Tandem Axle Boat trailer With 10,000 Lb CapacityTo 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...
view full answer... - Correct Replacement Master Cylinder for Dexter/Titan Model 20 Brake Actuator The Replacement Master Cylinder Assembly for Dexter Model 10 and Model 20 Brake Actuators part # T4749501042 is designed for Titan Model 10 and 20 Surge Brake Actuators for disc brakes. If you have drum brakes you'll need to use the part # T2374600 instead. I'm not sure what surge brake actuator you have but if you can let me know I'd be glad to try and confirm this for you. If you are unsure, look for any markings stamped into the coupler and or send some photos my way.
view full answer... - Can a Titan Model 10 Actuator for Drum Brakes be Used with Disc BrakesThe 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.
view full answer... - Replacement Master Cylinder For 1984 Trail-Mate Boat Trailer With Dico 10 Surg-O-Matic ActuatorIf you have drum brakes on your Trail-Rite boat trailer, the correct replacement master cylinder you need is part # DX66FR. You would also need the replacement orifice, part # T1209800. If you have disc brakes on your trailer the master cylinder you need is part # T4747100. For a reverse lock out solenoid, you will need the Solenoid Valve with Fittings for Reverse Lockout part # T4748800. This solenoid comes with the necessary fittings and installs in-line with the system. The 15 ft flexible...
view full answer... - Replacement Master Cylinder, Bearings, and Tires for Tandem Axle Trailer for 23 Cuddy Cabin BoatIt sounds like your new boat trailer hasn't been taken care of and you want an estimate on cost to get up and running. 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. The brand of coupler and model will determine the master cylinder needed. The size of the tires will be a big determining factor, and the bearing sizing is very important as the wrong...

- Can Drum Brake Actuator Be Used Temporarily on Trailer with Disc Brakes The problem with using a drum brake actuator with disc brakes is that it's not going to supply enough pressure to fully engage the assemblies. Drum brake actuators typically put out around 1,000 to 1,200 psi (sufficient for drum brake assemblies) but disc brake systems require around 1,600 psi, thus an actuator specifically designed for them. Because of this your braking power is going to be greatly reduced with your current setup. With a tandem axle trailer this could cause some issues,...
view full answer... - Will Titan Master Cylinder Assembly Fit Dico Hydraulic Brake ActuatorIf 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.
view full answer... - Converting Titan Model 20 Brake Actuator From Drum Brakes To Disc Trailer BrakesTo switch your Titan Model 20 Adjustable-Channel Brake Actuator # T1899100 from drum to disc trailer brakes you will need to change out the Master Cylinder Assembly # T4749501042. This will change your actuator into the # T4749800 that is for disc trailer brakes. You will need to add a Reverse Lockout Solenoid Valve # T4748800 if you do not already have one to prevent the trailer brakes from locking up when you back up the trailer.
view full answer... - Will the Replacement Master Cylinder Assembly # T4749501042 Work on a Cronkhite TrailerIf 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,...
view full answer... - Troubleshooting Disc Brake Performance on a 12,000lb Boat TrailerThere 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 in it,...
view full answer... - Can Titan Model 10 Drum Brake Actuator be Converted to Disk BrakesIf 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. For a lockout solenoid you would then want the part # T4748800. I attached a help article on adding disk brakes to a trailer as well.

- Can Titan Model 10 Actuator be Converted to Disk Brakes from DrumSince 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. I attached a help article that will walk you through that process.
view full answer... - Master Cylinder Needed for the Titan Model 20 Actuator for Drum Brakes with Drop # T4042700We do carry the master cylinders for the Titan Model 20 Brake Actuators. If you have drum brakes, then you will want master cylinder # DX66FR. We also carry the master cylinder with the brackets as part # T2374600. If you have disc brakes, then you will want master cylinder # T4747100, or with the brackets, # T4749501042.
view full answer... - Do Brake Actuator Master Cylinders Have Weight CapacitiesThe 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 # DX66FR. We also offer a replacement master cylinder for a disc brake Model 10 actuator. That part number is # T4749501042....
view full answer... - Replacement Master Cylinder for Titan Model 10 or Model 20 ActuatorThe 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. If you have a drum brake actuator you would need the Replacement Master Cylinder Assembly for Titan Model 10 and Model 20 Brake Actuators # T2374600. If you have a disc brake actuator you would need the Replacement Master Cylinder Assembly...
