I now this sounds weird, but the 3/16 lines to the front wheels are bubble flare and if it has a single 1/4 line to the rear it is standard double flare. If it has 2 3/16 lines to the rear, they will be bubble. They don't bubble flare 1/4 inch line, I don't know why, But they don't. I'm not sure on how many couplings for inspection but as long as you use unions and not compression fittings you should be fine.

2003 santa fe-awd-how to install steel brake line

First, you have to make a new line. The steel brake lines are not available for ANY vehicle. The parts store will have sections of brake line that they can sell you. You should remove the old line and take it with yu so you can be sure and get the correct lenght and diameter.

You will then need either a "Bubble" flaring tool or a "Double" flaring tool depending on which type of flare your vehicle uses. You must look at the end of the original line to determine which it is. The steel brake line that you buy from the parts store will have double flares on both ends. To get the correct length howerver, you will most likely have to purchace a tube that is too long or your vehicle then cut one end off. You will then have to flare the end you cut.

NOTE: if your vehicle is equipped with metric bubble flares, there are also adapters that can be purchased that will screw into the bubble flare on your vehicle and adapt the fitting so that a standard double flare can be used on the tubing.

I recommend replacing the entire brake line from fitting to fitting. This can be very difficult to do, but it can be done. You may have to purchase a "roll" of bulk tubing to get a piece long enough to do this.
Some people do not want to go through all of this trouble, so they find a spot in the line that is in fairly good condition and cut the line. If you opt for this method, then you must now make a flare in the end of the line that you just cut off so the pieces can be "spliced" together.

When joining two pieces of line together, it is imperative that you use a flare union, NOT a compression fitting union. Brake lines must hold an extreme pressure (1100 - 1500 Psi.) using compression fittings is NOT SAFE.

Other than that, all I can tell you about HOW to change the line, is that you may have to disassemble several brackets and holders to get the old line out and the new line in depending on which line you are replacing and where it is routed.

Small hole in brake line near left rear tire

unfortunately the only thing you can do is replace it. no one makes pre formed lines so you can either remove the damaged one, and take it to a parts house, match the length, and fittings then take it home, bend it by hand which is very easy to do you don't need a bender so don't waste your money on one, and bleed the brakes. or you can track one down at a wrecking yard that came off the same rig. their are no way to patch these lines, I have temporarily fixed them before by completely cutting it in half where the hole is located, and then buying a brass union fitting at a local parts house and splicing it. I would not recommend this for a permanent fix

Are all the flare nuts "double flare" onthe brake lines-must replace them all because of rust---- any bubble flares

sorry only double flared and fittings are allowed on brake lines, not only for security but also by law, a flaring tool is not that expensive and neither are brake lines, what costs the most is the labor time to make and install lines

I have a 1990 Chevy short wheels base truck, actualy it's a SS 454 edition, and the brake line to the rear is rusted and has a hole in it right above the gas tank. How is the best way to fix it?

Take a pair of cutters and cut the rusted line on both sides of the gas tank and at the fitting for the rubber hose going to the axle. Pull the line out from behind the tank (it is in plastic retainers so it may be hard but just pull, it will come). There should be a union near the front somewhere, cut the line there also. Use a roll of new bulk steel line and a DOUBLE flaring tool and the necessary fittings. Put the fitting for the rear on the line and flare it, tape the fitting to the line so it doesn't move while installing. Now roll some line out straight and fish it through between the tank and frame making any bends you need as you go. Bend line as needed and attach rear fitting to axle hose. Then cut, install fitting and flare front of line where needed. Attach front of line and bleed the system.

Rusted Brake Lines

Yes pi is avery serious problem. If you are unfamiliar with shaping steel lines and double-flaring steel lines, leave it to a pro. After repairs are completed, brake system will need to be bled of air . Hope this helps

2 issues...Brake tube rusted and random cylinder misfire

1. What is the OEM diameter of the tubing? I plan to use plain steel, not stainless. If they use salt on the roads stainless is better, TUBING IS 3/16"
2. Once I get the tube bent, would it hurt anything to paint them with rust bullet? No for mild steel, stainless won't rust though, no paint req'ed
3. So I know what flaring tool to get, what kind of flares are on the ends of the tube? U will need a tool that does double flares, around $60 US, if u have ever used a double flare tool read the instructions carefully.
As far as OD of line, take the old to the parts store and match it, but I think it is 3/16"

The engine issue, best u have a trouble code test run and go from there, any Kragen or Autozone will do it for free, if nothing shows clean the inside of the MAF sensor with CRC brand MAF cleaner, water could not get in the line because there is over 40 pounds of pressure, u would see allot of gas on the ground under the truck.

My rear wheel brakeline on durango 1998 blew

Depends on your mechanic ablilites. Steel brake line is basically 0.188 inch diameter line, and the metric 6mm line dia is very closely same.
Dodge uses ISO bubble flare , and not the American standard double flare at the end of the steel tube line. This ISO bubble flare on the steel line then fits into its mate female end which is the rubber hose connector end.
So, easiest way to get rid of the ISO bubble flare and change to American double flare end is:
Some automotive stores such as Parts Plus Auto Stores carry the brass brakeline adapter which has one end being the male end that fits nicely into the rubber hose with its ISO bubble female fitting, while the other end of the brass line adapter is the female end which has the double flare so you can then insert the steel line replacement with standard double flare into this end of the adapter.
Steel line , bungy brake line or equivalent is fine, and has the brake line nuts already on it, and is flared for you too. If you want to stay with ISO bubble line fittings you can get that in bungy brake line lengths too but it is less common for some stores to carry, and that is why the conversion brake line fitting adapter mentioned is so easy a way to change from ISO bubble flare to a double flare for easier use of all steel line being standard American double flared brake line. The brake lines come in straight lengths, 2ft 4ft, and 6ft, so you can use them to fit your necessary total length by connecting them with tubing couplers which the steel tube lines brake line nut gets threaded into.
My same year Durango had its rear line blow thru last year, due to the rusting of the steel brake line. I just got done last week, doing a entire steel line replacement myself. It was a medium sized effort for sure. You should check the other lines for the entire brake system to see if you need to replace more than just that section which failed for you, as my lines showed heavy corrosion at many other locations in the brake line system.
It is easy to double flare brake line tubing , and Sears sells its craftsman brand of brake line double flare tool kit for that purpose at about 60 bucks if I recall it right.
One thing you should do when doing your own double flaring, is to use a dial caliper to measure the diameter of the flare at its widest flared end, to insure you are within the required diameter of flare to insure proper sealing when you tighten down the tube flare nuts. I recall the flare diameter is supposed to be 0.272 inches , plus or minus 0.006 inches ( so range of dial caliper measuring of that formed flare should be between 0.266 inch and 0.278 inch) to insure the right diameter of flare for good sealing.
You can also get steel galvanized tubing line in coils of 20ft and more, with a bunch of brake line nuts ( all this is standard american brake line nuts, for double flared line fitting) from Inline Tube company;
Check out the great tech info from FEDHILL website,
Good luck, I did it so you can do it and feel satisfied and safe for the family with solid and sound steel line that is much better than chancing an accident via leaving the rusted line in place.
