When you apply the brakes in your tow vehicle, deceleration occurs and momentum pushes your trailer toward the rear of your vehicle. With surge brake systems, the actuator is triggered as your trailer moves forward while the tow vehicle slows. The actuator telescopes, applying force to its master cylinder, which in turn supplies the necessary hydraulic pressure to engage the trailer's brakes.

Because this model does not include a reverse lockout, it is recommended that you equip your trailer with free-backing brakes so that you can drive in reverse without triggering your trailer's brakes.

Amazing service, best price on the internet, best shipping rate and fast shipping.
I live in British Columbia Canada and was told by local suppliers it would take 6 weeks to get one in. I received this in just over a week from the other side of the USA. AMAZING

  • Master Cylinder Needed for the Titan Model 20 Actuator for Drum Brakes with Drop # T4042700
    We 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.

  • Disc Master Cylinder and Reverse Lock Out Recommendation for Titan Model 20 Actuator
    To 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.

  • How to Identify Brake Assembly for Triple Axle Boat Trailer
    Hi Scott; I don't have a way of knowing the exact brakes you need, but I can help you figure it out. Based on the 6 on 5-1/2 bolt pattern you have 3,500 lb - 6,000 lb axles. I would look on the trailer axles to see if you can find an axle tag to identify them. The capacity is probably listed. but if you don't see it the manufacturer can identify it using the serial number. Assuming you're looking for hydraulic drum brakes you can use the etrailer Hydraulic Trailer Brakes - Uni-Servo -...

  • Parts to Replace Hydraulic Brake System on a 2004 Magic Tilt Trailer
    We can definitely get you started with parts for your Magic Tilt Trailer, but we will need some additional information to complete your parts list. We can start with a coupler. Since your boat trailer will not exceed 10,260 lbs, I recommend looking at a coupler like the Titan Zinc-Plated Brake Actuator for Disc Brakes, # T4750620. This coupler has a 3 inch drop like the coupler you referenced, but it has a 12,500 lb weight capacity which is closer to the weight of your trailer. Using...

  • How to Determine if a Trailer Brake Actuator is for Drum or Disc Brakes
    If the psi rating is listed on top of the actuator you can tell by that, or it may say drum or disc brakes on it. If the psi rating is there drum brake actuators put out up to 1000 psi. Disc brakes will put out up to 1600 psi. Otherwise they will look identical. The only other way to tell without a part number would be the fitting at the back of the master cylinder. On the inside of the fitting there will be a check valve, a narrower opening, indicating a drum brake actuator. But without...
