  • Recommended Replacement for Model 70LP Surge Brake Actuator
  • While we don't have replacement parts for a Model 70LP actuator, we do have a great replacement for it. Like the 70LP, these actuators are a fit for a 2" hitch ball, but they just have a slightly larger capacity at 7,500 lbs. You didn't mention whether you had drum or disc brakes so I'll give the options for both: - Drum Brakes: Dexter DX7.5 Drop-N-Go Brake Actuator - Drum Brakes # 099-175-00 - Disc Brakes: Dexter DX7.5 Drop-N-Go Brake Actuator - Disc Brakes # 099-175-20 I've added...

  • Brake Controller Solution for 2017 Chevy Silverado that Doesn't Like Electric Over Hydraulic Brakes
  • Factory integrated brake controllers in newer trucks are not always reliable with electric over hydraulic actuators. The newer trucks mostly all say their integrated controllers work with the EOH setups but we've found that it isn't always the case. What you described happening is an example of an integrated controller not working right with the actuator so an aftermarket controller will be your best option. The Prodigy P3 part # 90195 will be your best option. This is our most reliable...

  • Replacement for Atwood 82543 Surge Brake Actuator
  • The closest option we have to replace your Atwood 82543 actuator is part # 8605001, which is the item you referenced. However, this actuator doesn't have the lockout like your Atwood does. For a lockout use # T4748800 as an electric lockout. It wires into the reverse lights on your vehicle via the circuit on your trailer connector.

  • Recommended Replacement for Atwood Surge Brake Actuator 85778
  • The manual lockout on your Atwood 85778 surge brake coupler is there so that you can back up the trailer without the brakes locking up on you. Yes you can safely tow your trailer with the broken manual lockout, you just have to make sure you don't put yourself in the situation where you have to back your trailer up. Since Atwood went out of business there aren't any exact replacements for your coupler but you can use a different brand. The only thing I was able to find online about the...

  • Replacement for Atwood 61101 Brake Actuator
  • The Demco Hydraulic Trailer Brake Actuator part # 8605001 should be a direct replacement for the Atwood 61101 Brake Actuator that you have now. This is a bolt on option that mounts on 3" centers. The review you are referring to, the customer did indeed weld the brake actuator to his tongue but this is not required for installation because it is a bolt-on actuator. Unfortunately, we do no offer a bolt-on brake actuator for drum brakes with a manual lockout that will work for you therefore...

In regards to differences, Demco makes a wide range of different trailer and towing products whereas Titan specializes more in trailer brakes.

  • Availability of Replacement Master Cylinder for Atwood 85778 Actuator
  • The Atwood master cylinder 85841 is no longer available. Atwood doesn't product any actuator components anymore so it's getting harder and harder to track down replacement parts.

This will also ensure that replacement parts will be readily available if needed down the line. To replace the Atwood 85778 model...

  • Master Cylinder to Convert Titan Surge-o-Matic Model 6 Actuator to Disc Brake Operation
  • You are correct that disc brakes require an actuator with higher psi pressure than what is required by drum brakes. Drum brakes need pressure of 1000-psi but discs need 1500 to 1600-psi. You can convert your Titan Surge-O-Matic Model 6 actuator to disc brake operation by replacing the master cylinder with part # T1777405. This kit includes the master cylinder, mounting plate, hex bolt, push rod assembly and installation hardware. If your brakes locked up this should not be due to the...

If this is the case then what you need is an adapter that allows your OEM controller to communicate properly with the actuator. If you have the BrakeRite EHB # T4822500 for drum brakes or # T4813100 for disc brakes then you need the adapter # T4846000.

  • Does the Factory Brake Controller in a Ram 3500 Need An Adapter to Work with EOH Brakes

Therefore, you will need to use an adapter. Please also make sure that you are in the electric over hydraulic mode if that is an option. In order to recommend the correct adapter I will need to know what electric over hydraulic...

If this is the case then you can use the Replacement Shock # T1242600 to resolve the issues you're having.

For new brake lines you'll want to use the Kodiak Hydraulic Brake Line Kit # 18SI-BLKIT which will allow you to replace the brake lines on a trailer up to 18 feet long. There is also a 15 foot kit available with part # 15SI-BLKIT. I don't recommend running them outside of the frame since they could be pinched off quite easily, so we do...

We have found this to be the most reliable EOH actuator and it is designed to work with trailers with drum brakes that are 8,000 lbs or larger. The difference between this and the Hydrastar XL Electric-Hydraulic Brake Actuator # HBAC10-CLR is the fact that this unit comes with a...

  • Dexter EOH Disc Brake Actuator Response Time with GM Factory Brake Controller
  • EOH actuators do differ in their response time. From the moment you press the brake pedal the time needed for the pump in the EOH actuator to build hydraulic pressure and push that through your brake lines, through the T fittings, and to your disc brakes can easily be as much as 2 seconds. Longer trailer brake lines and more axles with brakes both can mean the time can be slightly longer for pressure to reach all of the calipers and for you to feel the trailer slowing down.

  • Trailer Surge Brake Actuator to Replace Atwood 85778
  • Atwood doen't manufacture trailer surge brake actuators anymore, but we do have a good replacement for you. I'd recommend the Demco # 8605001 for drum brakes or # DM8605101 for disc brakes. The actuating couplers are rated for up to 6000 GTW, are compatible with a 2 inch trailer ball and will fit your 3 inch wide channel tongue. Neither actuator has an electric lockout, it's not really necessary on the drum brake model since drum brakes don't work well in reverse, but if you use the...

  • Replacement for Titan Model 6 Trailer Brake Actuator
  • That is a great photo, thank you; and while there are certain repair parts available for a Titan Model 6, I recommend replacing it altogether. The reason for this is the corrosion looks to have taken its toll on the actuator, and is at the point where a replacement makes the most sense in terms of safety and value. The Titan Model 60 is still a good option, and the right one will depend on if you have disc or drum brakes: - Disc Brakes: Titan Zinc-Plated Brake Actuator - Disc - 2-5/16"...

  • Disc Brake Actuator with Electric Lockout for Magic Tilt Trailer
  • For your Magic-Tilt tandem axle boat trailer with disc brakes and a straight tongue I recommend Titan Disc Brake Actuator Coupler # T4745720.

Since you have a Dico Aero 6000 actuator the correct replacement shock would then be the part # T4502000. If you do determine it's the master cylinder or you just want to replace it now while you have it apart you'd want the part # T4395100 for if you have drum brakes or part # T4714200042 for if you have disc.
