Flexible Rubber Brake Hose

This Kodiak brake hose is made of rubber, making it a practical choice for a variety of applications. Because you can easily bend it, a rubber hose is simpler to work with than a rigid stainless steel brake line. This flexibility makes a rubber hose great for use with foldaway trailer tongues because it is less likely to kink or break when bent. In addition, rubber hoses allow for a wide range of motion so articulating parts can effectively function. These qualities make rubber hoses better suited than steel lines for trailers with torsion axle suspension systems and trailers that have disc brakes.

Stainless steel brake lines have braided exteriors, which can not only wear against exterior surfaces, but also against the interior lining of the hose if dirt gets underneath the steel braid. And if the braid on a stainless steel line tears, it can cut into the hose lining. The exterior surface of this hose is solid rubber, so there are no crevices for debris to enter.

Durable Fittings with Deep Threads

Kodiak Hose Flare

Kodiak brake hoses have corrosion-resistant brass fittings with stainless steel flares. These fittings have a gap built into them that allows room for a line wrench - also called a flare nut wrench - to slide over the line and down to the nut. This type of wrench grips the nut better than a standard open-ended wrench so there is less chance of stripping the threads as you tighten down the nut.

The stainless steel that is used to create the flares on this hose is stronger than brass. As a result, these fittings are more durable than ones made entirely of brass. The stainless flares are primarily designed to keep the fittings from splitting when you tighten them down, but they offer absolute rust protection as well.

Kodiak's fittings have deeper threads than many other fittings on the market to provide a higher thread engagement. Deeper threads offer an advantage when used with fittings that have the same thread depth. These Kodiak fittings will work with most fittings on the market, but when they're used with other Kodiak fittings, the result is a stronger connection with fewer leaks.

Item is as described and fit perfectly with mu MFI trailer application.


The performance of these disc brakes are excellent. The installation was a breeze.


Hi George, you're welcome. I have made several purchases from E Trailer, things have always worked out great.


Garbage it exploded first trip out!!!

To be honest we have had a similar review before with this hose. It does have a three year warranty if you still have the hose and are interested. I would be happy to send the details to you.


Exactly what I was wanting.


Great replacement for my steel line, customer support was great at answering my questions if it would work on my trailer.


Product came apart on second trip poor manufacturing same end pulled off the hose went less than 100 miles

I would say this experience with the hose is not typical with the Kodiak brand. It does have a three year warranty if you still have the hose and are interested. I would be happy to send the details to you.


Great products at fair prices. Mike D’s customers service was excellent & and far exceeded my expectations. He is a true asset to the company.


This break line set, and the disk break set I ordered about a year ago are holding up great on by boat trailer. It is used only in salt water. they are a big improvement over the first set that came with the trailer. These are the only ones I will be buying from now on.

John P.


Holding up great. I have had no problems with them and the boat gets used a lot. I do flush them out with fresh water as soon as I get home. It seems thats all they need. GREAT product.


My drum brakes locked up on me because it is a boat trailer and gets submerged in water. I hate drum brakes, due how many part are inside and can rust up. I am the 3rd owner of my 1998 boat trailer and it was hard to figure out what I needed to fix it. I contacted etrailer and they were super helpful, super informative and super easy to work with. I told them what I had, and what I wanted to do., and they put a package together for me and that was them. Everything was super east to install because it is all bolt on. I did have to do some cutting and grinding on my old tongue because the master was welded on. That was the only difficult part. My new setup is amazing and the disk brakes and new master make it feel like my boat is not even there. All in all, I am 110% satisfied and will definitely be a returning customer for any trailer needs. Thank you etrailer for making everything super easy.


Easy to install and works fantastic. I would recommend this to anyone needing to add a breakaway on boat trailer for space.


I have made 3 orders and each has been on-time, accurate, and complete. Which says a lot about their website as well as service.


Arrived on time and was the product that I needed.


I needed a brake line hose for my boat trailer. This was perfect and didn't require bending or flaring.

Quick service and delivery!



Sold the boat and trailer. Havent heard a negative from new owner.


The hose was manufactured six months ago How sweat is that, The hose was even shipped with plugged ins. This will help and bleeding the lines thanks again


Perfect replacement brake line for trailer brakes on a 2014 Marine Master boat trailer with UFP calipers. Replaced the line that runs from one caliper to the other along the axel. Easy install.


Just as I expected


This has been a great product. I used it on a boat trailer after installing a swing tongue, it was easy to install and has worked well. Product is very durable and has stood up well after one year of use. In fact it still looks like new. i am very pleased with my purchase and would recommend this product.


Good products


Being a somewhat difficult to find length with the correct fittings, we were happy to find that etrailer had this available for prompt shipment. Our EOH system is back online!


Replaced the metal tubing that originally came on my 2004 four winns trailer this is way more practical and almost bullet proof!!!


Joanne was extremely helpful and the order arrived only
about a week early! All parts for 10 inch disc brakes worked.


Web site worked very well. Received the brake lines within a reasonable time frame since they had to go all the way to the west coast. Product was easy to find on their site and they were exactly as shown. Prices were within budget and much easier that fighting traffic locally.

I will order again from them when needed.


The brake hoses were of the highest quality. Thanks.


Very well made and plenty of flex in the line to accommodate the movement required in the caliper when mounted on the trailer. SS hose ends are well made. Nice quality

  • 20' Long Kodiak Hydraulic Brake Hose Availability
    I believe you're looking for the Kodiak Hydraulic Brake Hose - 3/16" Male Fittings w/ Stainless Flares - 1/8" ID - 20' # bh-3mfs-20. At this length I assume that you're wanting to run this hose the length of the trailer so I do want to note that if you have an electric over hydraulic actuator then the hose will typically wear faster than a stainless steel brake line. The lifespan is typically 5+ years, which exceeds the 3-year manufacturer warranty and with the hose being as low cost as...

  • Recommended 18' and 7' Long Brake Lines With 3/16" Fittings That Use 3/8" x 24 Thread
    I recommend replacing your current 17' brake line with the Kodiak Hydraulic Brake Hose - 3/16" Male Fittings w/ Stainless Flares - 1/8" ID - 18' # bh-3mfs-18, and your two 7' lines with two of the Kodiak Hydraulic Brake Hose - 3/16" Male Fittings w/ Stainless Flares - 1/8" ID - 7' # bh-3mfs-7. Each of these brake lines have the same 3/16" fittings with 3/8" x 24 thread so they will be an exact replacement, and the rubber hose with stainless steel fittings will hold up great in salt water...

  • How To Determine Which Part Is Needed To Replace a Brake Line To the Wheel On a Trailer
    I don't have a way to look up the exact replacement brake line for any one given trailer but I since these brake lines all use standard fittings sizes I can still offer some options. The best option we could offer would be a rubber replacement as that is pretty much what we carry but don't worry as you can mix rubber and hard lines no problem. The main thing this comes down to is what length you need. The Kodiak Hydraulic Brake Hose part # bh-3mfs-7 for 7' long or part # bh-3mfs-2 for 2'...

  • Shorter Brake Line Recommendation than Kodiak Hydraulic Brake Hose BH-3MFS-20
    We have the 7 foot section part # BH-3MFS-7 which is the shorter version of the # BH-3MFS-20 that you referenced. Or for just slightly shorter we have the 18 foot long section part # BH-3MFS-18.

  • How To Choose Correct Flexible Brake Hose for Brake Actuator
    The fitting on the back of a brake actuator should be a 3/16". Therefore, all you'll need to know is the distance from the actuator to the tee fitting. This would be different for each application swing away adapter or not so I cannot exactly info of this for you. The Kodiak Hydraulic Brake Hose part # bh-3mfs-7 is 7' long for example. There can also be unions added if you need to extend or you can choose a different length from the list below.

  • Brake Lines for a 1999 Baybreeze/Seabreeze RV
    We do have brake lines you can use with your RV. Brake lines are not vehicle specific though so you can use any lines provided they are long enough and have the proper fittings on them. I have included a link to our selection of brake lines. If you can tell me how long your RV is I can make a more specific recommendation. If your RV has drum brakes then you can use all metal lines. If it has disc brakes you will want a combination of metal lines (from the master cylinder back to the axle)...

    There are several brake lines in varying lengths and sizes between your disc brake assembly and the surge brake coupler on your trailer. I am not sure which one you are looking for but if you can pinpoint this for me I may have some better advice for you. In the meantime, I have attached for you a photo that shows what brake lines go to and from a disc brake assembly and surge brake coupler on a tandem axle trailer.

  • Does the 7' Kodiak Hydraulic Brake Hose bh-3mfs-7 Come with 45 or 90 Degree Fittings
    The Kodiak Hydraulic Brake Hose part # bh-3mfs-7 does not come with 45 or 90 degree fittings but you could add these with the Kodiak Hydraulic Brake Hose part # bh-3mfs90-1-5 and Kodiak Union Fitting part # BH-C-3FIF. In which case you might want to step down to the Kodiak Hydraulic Brake Hose part # BH-3MFS-3-5.

  • Is There a 90 Degree Adapter for the Kodiak Hydraulic Brake Hose
    The Kodiak Elbow Fitting for Hydraulic Brake Hose part # BH-L-3FIF will work with the Kodiak Hydraulic Brake Hose part # bh-3mfs-7. The Kodiak Hydraulic Brake Hose part # bh-3mfs90-1-5 could then be used to attach to the caliper or you could exclude this and the elbow and just use the Kodiak Hydraulic Brake Hose part # bh-3mfs90ff-1-5.

  • Solution for Needing 87 inches of Trailer Brake Line
    The best option would be our 10 foot long section part # T1074500 most likely. It's a steel cable so you would need to coil the excess. Of if you can get away with 84 inches we have the part # bh-3mfs-7. We don't have exactly 87 inches.

  • Trouble Preventing Brass Brake Line Fittings From Leaking On a Trailer
    The majority of our brake line fittings are made from brass which are a bit different than the steel brake line fittings you might be familiar with on a passenger vehicle. Generally speaking, the cause of these brass brake line fittings leaking is usually related to over-tightening as they are just not designed to be torqued to the same specification as the steel brake line fittings. I recommend you start by tightening the fittings by hand tight, then around 2-3 full rotations with a wrench....

    We carry brake lines in various sizes and materials that you can see on the page I linked for you. These include both steel lines and flexible lines and both complete brake line kits like # DM5429 as well as individual lines. For a 7-foot flexible line with 3/16-inch male fittings you can use Kodiak # BH-3MFS-7 or for a shorter 4-1/2-footer part # BH-3MFS-4-5. For a 10-foot steel line you can use # T1074500. It is perfectly okay to replace a steel line with a flexible line. All such...

  • Rubber Versus Steel Brake Lines for Electric Over Hydro Conversion on Single Brake Axle Trailer
    As an installer, I much prefer rubber lines as they are easier to use. The steel lines are more durable but I can't say I've ever had a trailer we worked on come back with a broken rubber hose either. The steel lines are very hard to work with and if you want it to look decent you'll have to cut the lines to your exact length and flare on the fittings again. If you're experienced with brake lines and have the time to do it right and make it look nice then the steel lines work well but even...

    The Kodiak Hydraulic Brake Hose - 3/16" Male Fittings w/ Stainless Flares # BH-3MFS-7 will fit on your trailer if the 7 foot length is what you need. You most likely will need the Kodiak Union Fitting # BH-C-3FIF for that application.
