Flexible Rubber Brake Hoses

Kodiak brake hoses are made of rubber, making them a practical choice for a variety of applications. Because you can easily bend them, rubber hoses are simpler to work with than rigid stainless steel brake lines. This flexibility makes rubber hoses great for use with foldaway trailer tongues because they are 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 these hoses 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 these hoses 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.

The whole staff at etrailer bent over backwards to make sure I was satisfied with the installation of brakes on my trailer. Have made several purchases from them always satisfied with parts and service. Special credit to Jamie great to deal with. Answered all my questions and was very knowledgeable.

E trailer offered the best deal on the tires and brakes that I found. Fast shipping and curteous service from friendly staff (Ricky) made dealing with them easy and efficient. I will definitely shop with them in the future.

It is an excellent kit for a hydraulic brake upgrade; it had all the lines you needed to complete the job right!
by:
I put disc brakes on my 2015 Cardinal Trailer, the best decision I have ever made. Bought the pump through etrailer and have been more than satisfied.
by:
Delivered as promised. The short 18” lines that go to the calipers could use a 90 degree bend on one end.

all i can say after installing discs is i would never go back to electric brakes. After towing my Montana 5th wheel for thousands of miles over 12 years, it’s nice to know i can stop my rig

All parts fit and one year later are working well. I am glad I made the change from Electric drum to Electric over Hydraulic disk on my 6 ton RV
by:
The service was great and brakes are working wonderful. Exactly what I needed.

I just received this brake line kit and laid it out on the trailer...have not actually fully installed it yet. It lays out perfectly...looking like it will be a perfect fit for my tandem axel Magic Tilt trailer for my 21' boat. Quality looks solid. I'll post more after full installation.

Hose kit was as expected. etrailer is a great source for all my RV parts needs and I really appreciate their videos and technical support materials.

This is the Best money I have ever spent in regards to safety and peace of mind. I previously had drum brakes which would take a long time to dry out in the rain and we're impossible to adjust because of the drop axle.

  • Recommended Kit to Convert Brinkley Z3100 from Drum to Disc Brakes
    Hey Dwyane yes that is necessary unfortunately. We do have disc brake kits like the DeeMaxx Disc Brake Kit # DE68YR which will work with 7,000 lb axles that uses specific bearings. The last couple of things you'd need is a brake line kit # 18TA-BLKIT as well as an actuator # DE47SR and a breakaway kit # 3802308. If you can let me know what size axles you have as well as what bearings it uses, I'd be happy to find the correct kit.

  • Recommended Drum to Disc Brake Kit for a 3500 lb Tandem Axle Boat Trailer
    Mark, the Kodiak Disc Brake Kit # K2HR35DKG appears to be what you're looking for but you're going to need to verify which bearings your trailer uses right now to make sure it's compatible. The bearings, actuator # DX29FR and brake lines # 18TA-BLKIT would need to be added separately as well.

  • Disc Brakes for 2022 Road King Boat Trailer With Dexter Vortex Hubs
    Hey David! For a disc brake conversion I recommend the DeeMaxx Disc Brake Kit # DE42FR. These are designed to fit a 5 on 4-1/2 bolt pattern and are rated for 3,500 lb axles. Make sure this matches your axle capacity. They are also compatible with your Dexter Vortex hubs. This is a pair of brakes so you will need a quantity of two with tandem axles. For a surge brake actuator I recommend the Demco Hydraulic Brake Actuator w/ Electric Lockout # DM62VR. You will also need the Kodiak Hydraulic...

  • Best Way To Secure Hydraulic Brake Lines To A Trailer Axle
    Hey Chris, thanks for reaching out, and good question. For that, the best practice is usually rubber-coated metal clamps, also known as Adel clamps, secured to the axle with self-tapping screws or weld-on tabs. That keeps the brake lines from vibrating, rubbing through, or getting beat up by road shock. You want the lines snug enough that they can’t flop around but not clamped so tight they pinch the hose. A lot of folks also run the hose slightly behind or on top of the axle tube for...

  • Restoring Brakes On A 1990s Boat Trailer
    Hello Doug, thanks for reaching out. You will need to replace the current coupler with a surge brake actuator. For that I recommend the Demco Hydraulic Brake Actuator like part # DM72VR which is for drum brakes, a 2" ball and bolts to a 3" tongue. It has mounting holes 3" apart on center. Please confirm that these specs match your trailer. You can run the brake lines thru the tongue, you just need to make sure and use a flexible line in the fold-away section. If you need all new brake...

    For your conversion to hydraulic brakes on your 7,000 lb dual axle RV, I recommend the Hydraulic Brake Kit - Uni-Servo - Free Backing - 12" - Left/Right Hand Assemblies - 5.5K to 7K # AKFBBRK-7. These assemblies are side specific and are labeled for you. These will work with your current hub and drum assemblies. For installation and adjustment, you will want the Brake Adjustment Spoon for Drum Brakes # W80630. If you need the mounting bolts for these assemblies, I recommend # BRKH12. If...

  • Replacement 10" Drum Hydraulic Trailer Brakes for Converting 3,500 lbs Axles to Hydraulic Brakes
    You sure can Mike. The etrailer Hydraulic Trailer Brakes item # AKUBRK-35 are going to work with your boat trailer's hubs. The only time you run into problems is going from hydraulic brakes to electric because you need a smooth surface for the magnets to grip. The Demco Hydraulic Brake Actuator item # DM72VR is the correct one for drum brakes. It does not have a manual or electric lockout so you'll need to add one with the Reverse Lockout Solenoid Kit item # DM5836 or use the Free Backing...

  • Recommended Disc Brake Kit for a Venture Salt Water Boat Trailer
    John, to replace the rotors and calipers for your TDE system on your boat trailer, I recommend going with the Kodiak Disc Brake Kit # K2R35D. This kit includes the rotors, calipers, the mounting brackets and mounting bolts, will work with your current actuator, and has a dacromet coating for superior protection against salt water and fresh water. The last thing you'll need is a brake line kit # 18SI-BLKIT for a single axle, or # 18TA-BLKIT for a tandem axle. Also since you mentioned...

    Hey Shaun, there isn't a kit that I'm aware of so you're going to have to piece together the kit with the: - Kodiak Hydraulic Brake Hose # bh-3mfs-7 for the 7' hose, - Kodiak Hydraulic Brake Hose # bh-3mfs-1-5 for the 1 1/2' hose, - Kodiak Hydraulic Brake Hose # BH-3MFS-3-5 for the 3 1/2' hose, & incase you want it, the Kodiak Hydraulic Brake Hose # bh-3mfs-20 for the 20' hose. These are listed as specific fits for certain kits, but as long as your brakes have 3/16" fittings with...

The only thing I would recommend changing is the brake lines, here’s the combination I would suggest: Hydrastar Marine Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi – # HS381-8067 (2) Kodiak Disc Brakes - 13" Hub/Rotor - 8 on 6-1/2 - Dacromet - 7,000 lbs - E-Z Lube – # KOD63FR Hydrastar Hydraulic Brake Line Kit - Tandem Axle...

    Hey Kimber, I had a chance to look at all those parts and I do not see anything wrong with what you've picked. The braking assemblies # K2R526DKG, hubs # 8-213-51UC1-EZ, brake line kit # 18TA-BLKIT, and the actuator all look good.

  • How Do Tandem Axle Hydraulic Brake Lines Typically Attach to Trailer Axles
    I believe what you mentioned is a standard way of running trailer brake lines on a tandem trailer. I attached a diagram for the brake line kit part # 18TA-BLKIT and how it normally connects to a trailer. The main feed line runs to the first axle where a Tee splits it off to run to either assembly on the axle. These lines attach directly to the axle.

    I will be happy to help you set up a new brake system for your Escort Trailer. I'll start from the back and work my way forward. I recommend the etrailer Hydraulic Brake Kit Left/Right Hand item # AKFBBRK-35-D. This is a 3,500 lbs set of brakes that are Marine-grade and designed for surge actuators. If you have a single axle trailer you will want the Kodiak Hydraulic Brake Line Kit item # 18SI-BLKIT. For tandem axle trailers you will need the Kodiak Hydraulic Brake Line Kit item # 18TA-BLKIT....

  • What Size Fittings Does Kodiak 225 Caliper Take
    Sounds like you are trying to install the wrong brake line to the Kodiak Disc Brake Caliper # KDBC225S that you mentioned.

  • Replacement Seals And Brake Lines for 2010 Mastercraft Tandem Axle Trailer
    Hey Preston! What is your axle capacity on the trailer? If those are 3,500 lb axles then you need 10-19 grease seals like # RG06-050 for a replacement. If you have a different capacity, let me know in the comments below or send me a picture of your axle tag for identification. Then for the brake line replacement you can use the Kodiak Hydraulic Brake Line Kit # 18TA-BLKIT (18') or # 20TA-BLKIT (20').

  • Tips for Bleeding Newly Installed Disc Trailer Brakes
    I have actually linked a video that will help you with the process of bleeding disc trailer brakes. Go to about the 9:40 mark of the video. It is basically the same as bleeding drum brakes: make sure the actuator is full of fluid, move the actuator in and out to push fluid and any air back to the calipers, loosen the top-most bleeder screw until fluid comes out. Tighten the bleeder screw and go on to the next brake assembly. Another option is to get a clear jar and some hose to run from...

  • Disc Brake Assemblies, Surge Brake & Brake Lines For 1989 Spartan Boat Trailer Tandem 3,500LB Axles
    First you will need to pull one of your hubs to verify the spindle size you have on your 1989 Spartan boat trailer. It likely has 3,500lb axles based on the weight of your 1993 BayLiner 2609 Rendezvous. To verify you will need a Digital Caliper # PTW80157 to measure the spindle(see image below). You should find a measurement of 1.719 for the grease seal, 1.378" for the inner bearing and 1.063" for the outer bearing. If you have anything else please let me know so I will be able to help...

    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. If you are looking to change all your brake lines on your 22 foot tandem axle trailer with disc brakes, I recommend the Kodiak Hydraulic Brake Line Kit # 18TA-BLKIT. This will give you everything you need (lines, fittings, clamps, etc) to replace your brake...

  • Replacement Surge Brake Actuator, Brake Lines & Calipers For 2005 Mastercraft Pro V 205 Boat Trailer
    I recommend the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX93FR for your 2005 Mastercraft Pro V 205 boat trailer. This weld-on disc brake actuator is for a 3" wide by 5" tall frame, and includes a electric reverse lockout. It latches to a 2" hitch ball and comes primed so you will be able to weld it onto your frame and paint to match the trailers frame. I do see that your boat can be fitted to a single axle trailer or tandem axle depending on your setup will decide what...

  • Correct Length of Kodiak Tandem Axle Brake Line Kit
    The Kodiak # 20TA-BLKIT 20 foot brake line kit will work if the distance from the rear of the coupler to the front trailer axle is roughly 18 to 19 feet, as you'll need some slack for the swing-away coupler to move freely. having a little extra length won't hurt, but you don't want to come up short because you can't easily make a splice like you can with steel brake lines. So in a nutshell, the advertised length of the kit you need will be the length of the longest line in the kit, and...

  • Should I Use Steel Brake Lines Or Rubber Brake Hoses For Adding Hydraulic Brake Lines?
    Using a Brake Line Kit # DM5403 that uses all steel lines with the only exception being the rubber lines down to the axle so the suspension can travel will give you the most consistent braking for your trailer. The steel lines will not expand like the rubber lines in the Kit # 18TA-BLKIT. While the steel lines will be more difficult to install and must be bent with the correct tools to prevent putting a kink in the lines it is the better option. You can often rent the tools needed for bending...

  • Bleeding Trailer Brakes and Air Bubbles Won't Stop
    If the air bubbles aren't ever stopping that indicates that air is getting introduced into the brake lines. Most likely through a bad master cylinder but since we know yours is a new part # T1777401 that would make me think that most likely you are leaving the bleeder open before releasing the master cylinder which is basically allowing the lines to suck air back in. Pressurize the system, open the valve, close the valve, release pressure.

    The Kodiak Disc Brake Kit part # K2R35S is the best all stainless steel disc brake kit we offer; the rotors, calipers, and mounting brackets are all made of stainless steel. In order to use this kit you'll also need a set of idler hubs, the Trailer Idler Hub Assembly part # AKIHUB-545-35-G-EZ-K but you won't be able to get these in stainless steel.

  • What brake line kit will work for a 2006 Shoreland'r Midwest Model SLR467ABBS
    Yes we do Ryan, thanks for choosing etrailer! I was able to match the brake lines based off your axle setup and overall trailer length for your boat trailer. So we just need the tandem axle hydraulic kit of the correct length. Kodiak Hydraulic Brake Line Kit # 18TA-BLKIT is 18' long main brake line for tandem axle trailers. Hydrastar Hydraulic Brake Line Kit # HS496-252 has a 25' long main brake line for tandem axle trailers. What are you typically launching from the Shoreland'r?
