Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this DeeMaxx 18 inch long rubber hydraulic brake line. It has the 3/16 of an inch brass male inverted flares on both ends. Now, this is a rubber flexible brake line. This will act as part of the hydraulic brake system. It does require additional lines and fittings that we do sell separately.
Basically, this line here is used to connect the disc brake caliper to the main brake lines. As you can see, it's rubber. It's a flexible construction, so it's perfect for disc brake assemblies, fold away trailer tongues, and torsion axles. As we've mentioned on each end, they use a brass male 3/16 of an inch inverted flare fittings, makes a better seal than steel fittings because brass is a little more pliable. This will help prevent leaks, splits, and corrosion.
And this rubber hose does meet the DOT Department of Transportation and the SAE standards. Specs again, overall length from end to end is 18 inches. The inner diameter of the hose is 1/8 of an inch. We mentioned the flare fittings on each end is 3/16 of an inch male inverted flare, and the thread size on those fittings is 3/8 of an inch by 24 threads per inch. But that should do it for the review on the DeeMaxx 18 inch long rubber hydraulic brake line with the 3/16 of an inch brass male inverted flares.

Awesome I finally found some flexible brake lines for my truck. I'm definitely going to be ordering more from y'all. I have a 2001 Toyota tundra and your brake lines have helped me tremendously because before my truck was busting the metal break lines over and over.
Do not order this product. The standard fittings for 3/16 flared brake lines have 3/8"-24 threads. This has something else. I'm not sure what the threads are, maybe they're some metric thread that someone through would be close enough, maybe they were made with really poor quality Chinese dies, whatever the story, the end fittings would not thread into 3/8"-24 fittings, they would start and turn a few threads then jam. Yes, I'm sure it was the firings on the hose which were the problem. I tried multiple fittings from multiple sources which all worked together nicely. I even checked with some good quality US made 3/8" 24 taps and dies The fittings on this hose were the one's which were the wrong size. Also, the flares on both ends of the hose were damaged.
The DeeMaxx kit worked well after trying to figure out the brake lines and where they should run. Installing the disks was slow at first as I wanted to make sure I was doing it right the first time. Bleeding the calipers was most effective having my wife in the truck, brakes on, brakes off. The test run was a challenge as we live in the mountains and there is very little level ground, not even the Walmart parking lot. The truck and 5th wheel combo stopped quicker than I have ever experience in the 28K miles we have traveled since 2020.
Top quality product. Worked very well.
Not even sure what to think; there’s only 3 items out of 6 in the box that I have received. I was planning to take my boat out this weekend and paid for fast shipping. This is very frustrating.
Brake hose fits perfectly.
Was hard to find item locally. And fit was great.
