Brake lines what is the availability of preformed brake lines?

Question edited for clarity. Wrong type of Brake - Break. Easy way to remember 'brAke' = Automobile.

They leak because they exposed to water and salt and they rust.

I have a GMC Yukon XL 2003 and I need to know what this part is. Can you help me

If the lines are that bad, there is no simple cure but to replace them!
Check with a dealer (I know, I cringe at this thought,too! LOL) if a kit of preformed lines is available for a reasonable price; otherwise, you or somebody else, will have to remove each line separately to replace it. You would need a bender and the proper flaring tool and wrenches to do the job right... some of the fitting nuts may be unique to those connections so far as size goes. If you have the time and patience and a helper, you can save the labor costs. You will also need to find out the proper way to bleed the whole system once you have finished!

You have several choices for brake lines. Probably your best is to buy a coil of brake line and run yourself another set. The better material and easier to bend is a nickel-copper blend. Volvo perfected the mix and it is suppose to survive a salt water bath for 18 years. You can reuse the line ends and then bend and flare the ends to match. A double crimp is needed for line ends so a flare kit with the double flare fixture is more desirable than resetting a single flare to make a second imprint.

Harbor Freight has some workable bending tools which should last long enough to do the job. Regular steel lines are cheaper but harder to bend.

There are preformed kits available, but suggest they may be designed to run in same crushed areas. You want to consider jacking the vehicle in the future. Run lines high on frame next to floor pan. Avoid catalytic converters. Run lines along inside facing surface of frame. Collision damage is usually on outside facing frame surface. This way brakes may survive side collision if you run the way I suggest.

This is a serious problem. Depending on what material you use, and who works on this car, will directly reflect on the price of the repair.

Many of the replacement parts have to be hand fitted. Some preformed lines are available, but they are often sold as a complete set.

There are special tools needed to create a brakeline out of a coil of material. Each end of brakeline would need to be crimped with the correct fitting for the individual inlet hole. Using different sizes of fitting is the Manufactuers method to insure that the brakeline fits in only the correct place.

This made more sense when replacements were bolt on parts and readily available. Today though, it is a complication to buy different size ends for each brakeline.

You are going to want to go either to a Brakeshop or someone who has done this work before. Consider this, all Brakelines were installed the same day on the Assembly line. If 2 leak now, it won't be long before all 4 leak. If you do not know the History of the car, and what was replaced earlier, you need someone to inspect the brakes.

The brake line needs to be replaced or repaired.

Here's a basic rundown on brake lines: Brake lines start at your master cylinder go to a main proportioning/combination valve to adjust brake pressure to front/rear of vehicle from here your brake lines will either go directly into your calipers on a disk brake setup or to a wheel cylinder on a drum brake set up. ABS or Antilock braking system is a computer assisted braking which generates numerous pulses per second to eliminate locking your brakes and loosing control of your vehicle. There are components which are needed by the system but as to hooking brake line to abs no. You can get preformed/exact replacement brake lines from dealer or some parts stores or you can get the correct length and a piping/tubing bender and form your own. Hope this clarifies things a bit. Need anything else let me know

You cant buy them.The best way is to have the lines made at a repair shop, they can bend and flare the ends. make sure they bend them correctly, just like the old ones,and put the lines back into the mounts. most lines are 3/16", some are 1/4". Make sure the bleeders are able to be loosened to bleed the air out of the system.

The tank has to be dropped to gain access to the top of it. You may be able to find preformed lines available from a manufacture like Dorman at a local parts store. Ford may actually still have the lines available, but being 18 years old there's no guarantee.

Depending on which brake line (front or rear) you can get a preformed brakeline from a chevy dealer, or possibly a parts store if an aftermarked fix is available. If not a local service center can usually patch in a new piece of line at the problem spot. The price of the line that is preformed will be quite expensive. If you have a "patch" job done to the line, the parts will be minimal, but the labor can add up as the service people will possibly have to bend and flare the lines to make them work.. which takes time, and they will enerally charge you a flat"hourly" rate for the service, which can add up as well.
