• Replacement For TDE LP7000 Surge Brake Actuator
• There isn't a rebuild kit, but you can definitely replace your TDE LP7000 brake actuator with one of the following, depending on if you have disc or drum brakes: - Drum Brakes: Dexter DX7.5L A-60 Brake Actuator # DX33FR - Disc Brakes: Dexter DX7.5L A-60 Brake Actuator # DX89FR These are both 7,500 lb actuators that accept a 2" hitch ball and bolt onto a 3" wide trailer tongue.

• Is Braking Affected By Switching From 6,000 lb to 8,000 lb Hydraulic Drum Brake Actuator
• Going from an actuator such as the Demco Hydraulic Trailer Brake Actuator - Drum Brakes - Zinc Plated - 2" Ball - 7,000 lbs # DM72VR to a larger one, the Titan Zinc-Plated Brake Actuator - Drum - 2-5/16" Ball - Bolt On - 8,000 lbs # T4079200 will slightly affect the braking. It will be a smidgen more rigid due to the added strength of the larger capacity actuator, but this is something that will be very minimal and won't affect the way your trailer rides. I have added a link to a video...

• What Kind Of Plug Do I Need In Order To Use The DX29FR Surge Brake Actuator
• The Dexter Surge Brake Actuator # DX29FR features an electric lockout. The surge brake actuator itself does not need to be plugged in to anything for it to work. The electric lockout does need to be wired if you want to be able to back up without locking up the brakes. The blue wire goes to your vehicles reverse light circuit, the white wire is a ground. This allows you to back the trailer up without actuating the brakes. Generally trailers with a surge brake actuator and electric lockout...

• Replacement 7,000 lb Surge Brake Actuator for Drum or Disc Brakes
• We definitely have surge brake actuators that can work, but the ones we carry are mounted on top of your trailer's channel tongue and you will need to drill new holes in order to mount them. Additionally, please note that these actuators are each designed to fit 3" wide channel tongues, so to ensure the proper fit you are going to want to measure your trailer tongue. Dexter actuators are premium quality which is why I highly recommend them, and the correct 7,000 lb actuator that works...

• My Brakes Are Activating When I Reverse Uphill What Can I Do?
• This likely means your hydraulic brake actuator does not have a reverse lockout. Reversing the trailer up an incline compresses the actuator and activates the brakes. Adding a lockout allows you to backup without actuating the brakes. We have the reverse lockout solenoid # DM11993 that can be added to your actuator. This will be wired to your reverse light circuit and will lock out the actuator when you are in reverse. We also offer actuators like the # T63FR which can be locked out manually.

• Replacement For TDE-LP750 Trailer Actuator
• We can get you a good replacement, though there is actually no longer a TDE brand. But that actuator is simply a bolt-on, 7,500 lb actuator that couples to a 2" hitch ball, and per the owner's manual does not have a lockout (so it is for free-backing brakes). The replacement you can use is from Dexter, and the right one will depend on if you have drum brakes or disc brakes: - Drum: Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-00 - Disc: Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-20

• Is There a Dexter DX7.5L A-60 Brake Actuator Primed That is Bolt On
• There is not because the Dexter DX7.5L A-60 Brake Actuator - Primed # DEX94FR is a weld-on actuator, and those are the only ones that are primed to be painted. Bolt-on actuators do come with zinc plating and are not primed for being painted, including the Dexter DX7.5L A-60 Brake Actuator - Bolt On - Drum - 2" Ball - Zinc - 7,500 lbs # DX33FR.

• Replacement For 7,500 lb Drum Brake Actuator For 3 Trailer Tongue
• The swing-away actuator was discontinued, and there is not a direct replacement, or a swing-away replacement, so what you'd need is a standard actuator. The Titan 7500 is a 7,500 lb drum brake actuator that couples to a 2" hitch ball, has a manual lockout, and mounts on a 3" trailer tongue, and there is an option for that: - Titan Brake Actuator with Manual Lockout - Bolt On - Drum - 2" Ball - 7,500 lbs # T63FR The # T63FR is the exact replacement you need, and will work the same way...

• Can Disc Brake Actuator be Connected With Elbow After Solenoid
• I don't see any reason why you can't connect an elbow to in the manner you are speaking of with a disc brake actuator like the Dexter DX7.5 Drop-N-Go Brake Actuator - Disc Brakes - 2" Ball - Zinc Plated - 7,500 lbs # 099-175-20. The shock in the actuator needs to be perfectly horizontal, of course, but there's no reason you can't attach a 90 degree elbow to ensure you can get the fit you need.

• Should There Be A Magnet Wired Near The Dexter EOH Actuator?
• There would not be any kind of magnet wired near an electric over hydraulic actuator like the Dexter # K71-651. Certain setups may require an adapter module # DX35FR to be wired near the actuator. This would only be required if your vehicles factory brake controller is not compatible with EOH systems.

• What Is Needed To Upgrade Brakes On Trailer With Tandem 7000 Lb Axles And Brakes On One Axle
• Disc brakes stop harder than drum brakes and require less maintenance. You will need to make sure the brakes all match if you are adding to the second axle. Also you will need to make sure you have the correct actuator. If you have drum brakes on your trailer, you will need to replace the brakes and actuator to those designed for disc brakes. I have attached a link to our product page for brakes that can be used for 7,000 lb axles. They are all 12 inch x 2 inch brakes. You can use the...

• Replacement For 6k - 8k Atwood Disc Brake Actuator
• Atwood is no longer in business, and the part number you asked about has unfortunately been discontinued, so it is no longer available. While I know it's not the answer you were looking for, the best option is a replacement for your Atwood actuator for disc brakes, and you can choose from the hitch ball size you need to couple to as well as the weight rating. Based on my research it looks like that master cylinder was for 6k to 8k rated actuators, so you can choose from any of the following...

• Determining If Surge Brake Actuator Has Lockout or If Brakes are Free-Backing
• The only way to turn a surge brake actuator "off" is to engage a lockout on the actuator. Some actuators have manual lockouts, others have electric lockouts, and some have no way to lock out the actuator. Typically, free-backing brakes are used with actuators that have no lockout. As long as the trailer brakes engaging when your tow vehicle is stopping, the brakes are working correctly. I have attached photos showing a manual lockout and electric lockout to help you determine if your actuator...

• Is There a Weld-On Demco Coupler for 2 Hitch Ball With Drum Brakes
• We do have an option for a weld-on coupler for drum brakes, but there is not a version of the Demco Hydraulic Trailer Brake Actuator 8605001 that is a weld-on option. The closest that can be welded on is the Demco Hydraulic Brake Actuator - Drum - Primed - 2" Bulldog Coupler - 7,000 lbs # DM8509202. The Demco actuator that can be welded on is very similar but has a higher 7,000 lb towing/700 lb tongue weight capacity.

• Is Actuator Needed with 10" Nev-R-Adjust Electric Brake Assembly # 23-468 and # 23-469
• When using the 10" Nev-R-Adjust Electric Brake Assembly for 3.5 K Axles, Left Hand # 23-468 and Right Hand # 23-469, you will not need an actuator for the brakes to function on the trailer. An actuator is used to pressurize the hydraulic brake system so it is not needed for electric brakes. In order to function, the Nev-R-Adjust brakes will need to be wired to your trailer connector. The brakes will then receive it's signal from a brake controller like the Tekonsha Prodigy P3, # 90195,...

• Weight of Demco Hydraulic Brake Actuating Coupler
• Minus the packaging, the Demco # DM62VR Hydraulic Brake Actuating Coupler weighs about 18 lbs. The coupler is compatible with trailers weighing up to 7000 lbs with disc brakes. The coupler fits a 2 inch trailer ball, and is equipped with an electric lockout solenoid that will prevent the brakes from engaging when the tow vehicle is shifted into reverse, assuming that the coupler is installed correctly and the center pin of the 7-way on the tow vehicle is tied into the reverse lamp circuit. If...

• Can I Use A Pressure Bleeder With The Dexter EOH Actuator K71-651
• The Dexter EOH actuator # K71-651 can absolutely be used with a pressure bleeder. The actuator has a standard brake bleeder nipple on the revivor which you can attach the hose of a power bleeder to for faster bleeding. We do not carry the YSTOOL brand, so I cannot say for sure if their kit will be compatible. We do have the hand pump bleeder # PTW87030 that will be compatible with the fitting on the Dexter EOH actuator.

• Will Titan Brake Actuator With Electric Lockout Allow Backing Trailer Up When Unhooked
• If you have a jack attached to the trailer frame you will be able to back the trailer up without actuating the brakes on the trailer when it is not connected. The # T4843300 will only make the brakes apply when the coupler is pushed .
