Will Disconnecting Brake Line Via Quick Disconnect Allow Backing up Trailer

Question

Question:

Im switching out my non working Atwood Surge brake actuator. My trailer has a quick disconnect line near the tongue. Going to install a new surge brake that does not have a manual lockout for backing up a hill. Just wondering if disconnecting the line via quick disconnect would also give me the same solution? just got the used trailer and not sure if the brake shoes are non lockout brakes.

That could potentially work but I'd be worried about putting too much pressure on the check valve on the actuator side and having that blow or forgetting to reconnect the line and traveling without active brakes (which could also blow the check valve). What I recommend doing is replacing your actuator with one like the Titan # T4339720 with an electric lockout and then using the kit # HM47890 to get the reverse signal sent to the actuator. When the actuator receives the reverse signal the solenoid then allows you to back up without your trailer brakes activating.

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

To find the load capacity for your axle you should look on the trailer VIN plate or sticker that lists the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that…

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…
