Brake Line Types
There are four types of hard line used for braking systems : steel, soft sword, stainless sword, and nickel-copper admixture. Each has it ’ s benefits and drawbacks. Steel – The most common type of hard line is galvanized meek steel. This is what the factory uses for all of the brake lines. Steel is low-cost, durable and easy to come by. The drawbacks are that steel rusts, and it is hard to bend. The rust is the biggest publish here. Brake fluid is highly hygroscopic, meaning it absorb water. even though the system is sealed, there is still moisture available at the top of the reservoir. As the brake fluid ages, it becomes more and more saturated with water. Water and steel equals rust. The absence of oxygen slows down the process, but not wholly. This is what leads to ruined bracken calipers and wheel cylinders. To fight this, the steel is galvanized. The publish of bending the brake lines can be overcome with flex tools, since steel tube is not promptly bent by hand . indulgent steel – The more exotic tube options are dearly-won, whereas steel is cheap. Where regular steel lines are hard to bend and prone to rust, there is another solution – Poly-Armour®. This type of brake occupation is the most normally sold at parts stores, including all NAPA Auto Parts Stores. Poly-Armour® is made of low-carbon sword, making it easier to bend. To protect against corrosion the sword is coated with Polyvinyl Fluoride ( PVF ), which is a credit card coat, that is baked and cured to the sword occupation. Unlike galvanize steel, the PVF coat does not flake or chip, leaving the steel substrate protected against rust, to the tune of 30 % better than galvanizing. many new vehicles are being built with Poly-Armour® lines.

Stainless steel – For the ultimate in hard lines, stainless steel steel is the solution. Stainless steel lines are impervious to rust, so they death everlastingly. Great, trouble solved. Hold on there buddy, stainless lines have a few drawbacks – namely, the monetary value. Stainless steel lines are expensive, three to four times more than regular sword lines. Stainless steel hard lines are not excessively difficult to bend, but flaring them is. You need a in truth good flaring tool to make good quality double flares with stainless steel steel tube. For show cars and street rods, the milled attend of stainless steel is odd. NiCopp® – In practice since the 1970s, nickel-copper hard lines have the intensity of sword, are rust proofread, and comfortable to bend. Because the lines bend then easy, they can be snaked through the chassis easily. Made of 90-10 bull to nickel, NiCopp® lines are reasonably priced as well. The biggest drawback of NiCopp® lines are handiness, as they may be hard to find locally .
Pre-Bent Or Bend It Yourself?
There are several ways to replace a bad hard cable. You could order a pre-bent line from your local anesthetic NAPA store, or you can bend one yourself. For those that need to bend a note yourself, the best solution is Poly-Armour® sticks. These are pre-flared lines that come in different lengths, with varying sizes and types of fittings. Poly-Armour® can be bent by bridge player or with deflection tools .
Tools For Bending Brake Lines
There are respective types of tools available, from bare radius tools to more accurate lever-action benders. The key to using a bend instrument is to get a quality tool that won ’ thymine kink the argumentation. While Poly-Armour® lines resist curl ( unlike plain steel ), it is silent possible to kink the line . simple carouse – These tools are one objet d’art and use a hook-type latch to lock the tube in space. You use one hand to hold the line and cock together, while the other hand bends the line. These tools are reasonably cheap and are very effective for ruining a piece of tubing. The don ’ t secure the line, complicated bends can easily become out of line, where your bends don ’ deoxythymidine monophosphate match the guidance they need to be.

Lever-action – This type of creature uses mechanical advantage to make flex lines easier. While the tube can still rotate ( allowing complex layouts become out of line ), it is easier to manage with a lever-action bender. Lever-type benders typically have multiple diameter positions, and marking for varying degrees of crouch. Most of these tools are designed for specific radius bends, there are tools for mean bends, tools for big bends. You can manipulate this to a degree by repositioning the line, making a larger radius, but you can ’ t make a smaller spoke than the joyride you have. Side note – The cheap version of lever-action benders that have an exchangeable die do not work identical well, they will normally just kink your line. Spring-type – This is a very basic curve meant chiefly for copper and aluminum tube. There are two types, home or external. Both prevent the tube from collapsing and kinking while hand flex. Best for easy, large diameter bends . once you have the proper tools, you can get your parts ready. If you are replacing a line, then you should have the existing line to use as a citation. Start at one end, and re-create the line flex for bend. You can even add some record as you go to keep the bends in line. If you are creating a new argumentation without a reference, you should make a reference. Bailing wire works very well for this job. It stayed bent, and you can use it precisely like you would an existing line. Plus it is truly cheap and has a thousand other uses around the shop .
The most significant factor that you need to keep in mind when bending brake lines- don ’ t forget the flares and fittings. even seasoned pros sometimes to forget to slide the fitting all the manner to the solar flare before bending the line, which means you have to either straighten the line or cut and reflare the production line. besides, when making bends near the end of the line, if you need to add a solar flare, do it BEFORE bending the line, your flare pass tool needs room ahead of the crouch, make certain you have adequate . Bending bracken lines is not unmanageable, but it does take a small rehearse to get good at it.
