How To: Replace Brake Hose and Line (Cutting, Flaring, and Bending)
Автокөліктер мен көлік құралдары
Brake line and brake hose wear out over time. Steel brake line corrodes, and rubber brake hose becomes less flexible over time and eventually cracks. Brake hose can also collapse and not allow brake fluid through, which can make the brake caliper stick, causing the vehicle to pull to one side during braking. Replacing brake hose is more common than replacing brake line, unless you live in a northern climate, where more frequent use of road salt can cause rust. Both brake hose and line can leak eventually. In this video we will show you how to properly replace brake hose, remove your old brake line, cut and flare new brake line, and then how to install it.

Park on a level surface.
Jack up your vehicle and put it on stands.
Brake hoses run from the wheel to the frame of the vehicle… and metal brake lines run from the frame to the master cylinder.
If brake fluid is leaking near a wheel, you’ll need to remove the wheel where you’ll be replacing hose or line.
Whether you’re replacing hose or line or both… when you detach an in-line fitting, you’ll want to use a plug or cap to keep excessive brake fluid from leaking.
There’s no specific way to plug the line… In many cases a short piece of hose with a bolt in the end of it works well.
Leaving the lid on the master cylinder keeps dirt and moisture out of the brake fluid, and slows the draining fluid while you plug the line.
Also, line wrenches are important for this type of job or any job where in-line fittings need to be loosened… the open end of the wrench has six sides rather than four.
They work pretty well with frozen fittings, and it sometimes helps to try tightening slightly before loosening… but if you run into excessive rust, you can use penetrating oil to help loosen things up.
[brake hose]
So let’s start by replacing the brake hose.
Have a drain pan in place under the wheel well.
Use your line wrench to loosen the nut holding the hose to the junction box.
Plug the hole at the junction box to keep it from leaking brake fluid.
Use pliers to remove the retaining clip… then remove the other end from the brake caliper.
Let the fluid from the hose run into the drain pan.
Once the old hose is removed, attach the new hose at the caliper first.
Now, remove the plug at the junction box… attach the hose there… and clip it into place.
Be sure to tighten fittings to manufacturer’s specifications to avoid leaks.
Repeat these steps for each brake hose that needs to be replaced.
After you’re done replacing all brake hose that needs replaced… if you’re not replacing brake line, you’ll need to top off your master cylinder and bleed your brake system to remove air from the lines [video link].
[brake line]
Now to replace brake line.
Depending on your vehicle, you may be able to replace an entire line as one piece… or you may need to replace shorter sections.

Seriously great video for someone trying to learn how to replace a line. He spoke clearly, slow but steady and explained with good detail. The video was also well done with great positioning , good lighting, good explanation while filming, showing and using the proper tools and why certain steps are necessary for a completely correct job on said vehicle. I will now look for videos with the O’Reillys stamp. Thanks again. 👍🏼
Wow, what a wonderfully detailed, perfectly executed how-to video. Thanks!
Tip about it being corrosive was very helpful. Amazing video overall!
Chris is a legend
Great video. I find it helpfull to put a drop of oil on the adapter stem on the flaring tool. Prevents binding that can snap the stem. Then clean oil off line.
After the line company I ordered from refused to replace the lines they sent with the wrong fittings this video really helped me out of a jam.
Sandwich bag and a zip tie works fine for capping hoses
great job on detailed instruction information and presentation for Brake line repair. thank you.
This video turned my $500 truck off of Facebook marketplace to a $3000 sell! There's hundreds of trucks on marketplace for $400-$600, and alls that's wrong with them are the break lines, and it's an easy fix!! This is how to make bank, I can do at least one vehicle a day while I'm young.
Complete video! Well done.
Really informative video, nice!
Great job guys
Wonderful mr thanks 👍👍👍👍👍👍👍👍💪
Thank you for the helpful video
Great help
great video man. I always laugh at how much more cautious some techs are. "If you get brake fluid on your skin wash it off immediately!" hahaha
Great video. I still don’t know if I’m up for it though.
Thank you so much.. we'll done ...🙏👍♥️✝️
Wish you had done a closeup of the double flaring of the brake line while you were doing it. Would have been great to see what it looked like after the adapter. Was it a bubble flare??
Good man
Thanks!!
I replaced the brake lines on my 96 Chrysler and hated every second of it 😂

@@zanderx7 Yeah, my question was geared more towards the removal of the entire line, and to get it back in there. I have an 08’ Honda civic and if you ever tried working in the engine bay, I was looking for a way around it, as the alt was to drop the motor and transmission lol. I upgraded to a bbk and wanted to redo all my lines, but instead I found a method that would allow me to run the BBK without any modifications having to be made to the abs module or brake lines themselves. Been going strong for a while now 😎. Appreciate it though
How about compression fittings on steel or nicopp fuel lines? Anyone know
This would be way better without the music.
I'm trying to put a pre-bent line in place and when I tighten the nut, the tube turns. I don't want to damage a $68 tube. How do I stop it turning when I turn the nut?

Oh if the brake hose is attached by a bracket or bolted loosen those first and you can connect it much easier,turn the new line bolt in by hand first the do the other side going to the cylinder/or caliper, then kinda wiggle the bracket back to the bolt holes and try to slowly put the brake hose brackets bolts back in,

What do you need to do if you don't plug the line & the brake fluid leaked out? Asking for my husband 🙄
Some up close and personal video of process would be useful as well even though this video is good
@2:31 the brake line plug linked as 16. Is not the right part. That is for the hose. Where can I find the brake line plug? It is not a threaded bolt it is the opposite. Female connector.
I used a steel fitting and it leaks..what should i do now?
Need brake line for 01 grand marquis?
How do you replace the break line
Nice video that person needed brakes pads
Reattached the end of the break hose just to un clip and un screw the break line seconds later.... seems like something I would do.
Sure about copper?
Such an amazing video you turned my $500 buy into a $3000 (Sale)-edit-(Sail) I love you O'Reilly
When you flare an existing steel line that can't be removed from the vehicle how do you hold the big vice while you're flaring the line? Just kidding but the professional who did the rear brakes on my 1980 Chevy K20 in 1979 used a pair of vice grips to tighten the rubber hose nut and rounded all the corners off. I will have to cut the steel line off and either try make a short piece of line to connect the new rubber line. The other option is to run a new copper line to an existing joint (about 8' away). The problem is that this joint is inside the frame with an exhaust pipe in the way. I can remove the exhaust pipe but I'm not sure I'll be able to loosen the joint. I'm converting the rear drum brakes to disc brakes with ruffstuff kit and not an easy job like all the KZread videos show,'
You do not have the fittings listed in the description, thanks otherwise though
Man my Dodge Durango has permanent brake hoses there no way to remove the hose alone you have to remove the whole brake line connected to it.
Great video, but the background music is incredibly annoying.

Should have done that last bend before you cut it.
You can also put a little bit of pressure on the brake pedal instead of capping the line, atleast some cars

Copper brake line is a great alternative to steel, with it being much easier to bend, cut and flare when replacing your own brake line. On top of that copper lines will not rust like their steel counterparts. Copper brake line is also DOT approved for hydraulic use, meaning it is strong enough for braking applications. Let us know if you have any other questions!

NEVER USE COPPER LINES FOR BRAKES!!! What he probably means is nickel-copper (ni-copp). Copper lines would be way too weak to use for brakes.
Brake lines should never be copper

They are not actually 100 percent pure copper. They are nickel-copper.
