Speaker 1: Today we're going to be taking a look at the Demco Hydraulic Brake Line Kit for Single Torsion Axle Trailers. This is going to work out for drum or disc brakes. Part number is DM5424. Now, when installing your brake line kit, you'll want to of course begin at your actuator. This is a surge style coupler. You may also have an electric over hydraulic type actuator.
Wherever your outlet is from your actuator, of course you'll want to remove any caps. Those are typically capped off to prevent any fluid from coming out if they do have it in it.We want our double flare here to go all the way up and sit flush in. Then we've got our flare that'll come down. Now, on the back side of our coupler, you'll see we've removed that protective shroud. It just has two 12 millimeter bolts.
It just gives us better access to our connection point here. We've threaded in our steel brake line. Now, if you already had hydraulic brakes, this is already going to exist. If not, you'll of course want to run your new lines to get those back to your braking system.This uses a 9/16 and it's a good idea to hold that as you tighten this just to prevent this from rotating. Now, you won't need to over tighten it.
Once we test it, if we have a leak, we can tighten it up just a little bit more. If it's still leaking, we'll tighten it up just a little bit more, but we don't want to over tighten it initially. Now, we're making a pretty long run here, so we're going to use not only the clamps provided with the kit to hold these on, but also some that we have here in the shop. This is part number A0250. I'm going to use #12 self-tapping screw to secure these along our way.Now as we run along here, you want to conform the brake line to your trailer, that way we can keep everything nice and safe.
I'm going to tuck in here. Then as we go back, we'll drop underneath those cross members. You can bend this line by hand. That's how we got it straightened out, but you can also pick up a pretty cheap tubing bender here. This can help out a lot for those little more difficult bends to make. That's available. Basically, it will just fit over, and that'll give you a good curvature here so you don't have to worry about pinching your brake line as you go.As we go along, of course we use plenty of the loom clamps just to keep it secure. You can see here where we have our cross members on our trailer. It's going to drop down and around. I think this is going to be more protected than it sitting on top where it may potentially be stepped on, or maybe as you're loading or unloading a boat, in this case, maybe the boat would make contact. Now we're ready to get our T-block installed. This is going to go on the frame rail of the trailer. It allows us to connect our main line in. Then we can send a line out to each side.Now, this needs to be in a pretty specific location depending on your application. Basically, you'll have your short hard line, and then you've got your rubber flex hose. Now, this rubber flex hose is going to connect to your caliper, so clearly we can't have this T so far away that this won't reach. So, I just mocked up how we're going to do it. You want this end in our T, this end to go up on our frame rail here, and then we need to make sure we've got enough room for our flexible line to come down and meet our caliper without it being stretched and it still having plenty of room to move up and down.As you can see, that looks like a pretty good spot. It looks like we're going to get everything where we need it. There's a tab that sticks off of the back of the T-block there. We're going to use a self-tapping screw here to secure it, but we want to hold here. That's what I've got marked on my frame rail. I'm going to drill my hole. The tab goes in and our self-tapping screw will go in and that'll prevent this from ever turning. Now we can get our block put in place and get it secured with our self-tapping screw. Nice and secure.Now you're going to have a little bit of bare metal there on that hole, so it's a good idea just to hit that with a little bit of spray paint. You can see the brake line that we have coming in from the front, it's just a little bit long. Now, you've got a couple options. You can create a coil. You want your coil to start at the top, though, and work its way down. Then you'd make a bend to go in the block, but what I'm going to do, I'm going to bring this back just a little bit. Just cut it, and we're going to use our double fl
