- Brake Flaring Kit: Or you can pick up an entire kit here if you don’t have any of the tools already on hand.
Do I use Teflon tape on brake line fittings?
You cannot safely, nor should you attempt to use Teflon tape on brake lines. A brake system should not rely on anything to stop a leak. The system relies on pushing a solvent under high pressure in a closed system for safe operation, and Teflon tape will threaten the integrity of that system.

What is compression fitting?
Compression fittings can join together parts or parts of steel brake lines to form a seal between the two parts. The pressure through the brake line is very high. Compression fittings usually cannot withstand such high pressures.
Why is brake line repair important?
Brake line maintenance: when to use compression joints. As many vehicles begin to age, brake line repair is an essential maintenance step. Brake lines are easy to become brittle, rust and leak, which reduces the reliability of the brake system. Exposure to natural elements is the main reason for the degradation of brake cable performance.
What is compression accessory?
Compression accessories can be used in non-public transportation vehicles, for example, off-road vehicles for recreation, or agricultural vehicles or work trucks that are not used on public roads. Any vehicle that is not driving on public roads and is not driving at high speeds can use compression fittings for brake repairs.
Can you use compression fittings on brake lines?
Because the compression fittings on the brake lines are not reliable, it is not recommended to use compression fittings extensively. However, compression fittings can be used in certain situations. If the brake line is to be repaired in a passenger car that is not used for daily road travel and transportation, compression fittings are acceptable ...
Should you replace brake lines on a passenger car?
For this reason, some states have illegally used compression accessories for passenger cars. Therefore, when handling passenger cars, it is recommended to always replace the brake lines, rather than repairing with compression joints.
Can you use compression fittings on public transportation?
Similarly, compression fittings are only allowed in vehicles that are not used for public transportation. For example, if you are renovating or repairing a car, you can choose to use compression fittings to repair the brake lines.
Why can't a shop use compression fittings?
A shop will never use compression fittings of any kind because they do not meet DOT standards even if they do exceed the pressure rating required.
What happens if you over tighten brake line spanner?
If you are untrained amateurs, you probably cross threaded the fittings causing them to leak. If you over tightened the fittings and deformed or cracked them, some leakage problems will arise. Also if you were not scrupulously clean and jammed some muck into the surfaces before you tightened, leaks. You could get the correct brake line spanner and go over every fitting again and see if you can get them slightly tighter, and see what happens under pressure.
Why don't we use pipe fittings?
The reason we don’t use pipe fittings is that we use steel tubing for brake lines. The tubing is too thin to accept NPT type pipe threads, so an adapter would have to be used to adapt from pipe to tube. Adapters like that use either flare or compression fittings, so we’d be right back to the original problem of sealing the tube fitting.
How much pressure can a steel compression fitting hold?
Steel compression fittings can hold up to 20x the pressure produced in a brake system and can therefore be used.
How much pressure is needed for a brake line?
That’s because they are incapable of safely dealing with the pressures involved. The pressure in a brake line can exceed 1,000 psi whilst the pressure in a mains water system is typically just 45–90 psi. A compression olive fitting is very likely to be just pulled off the brake line when very high brake pressure is applied.
What is compression fitting?
Compression fittings are made for variable pressure apllications and are even used in high pressure petrochemical lines as well as in aerospace situations. It is entirely dependant on using the correct size and material for the application.
What type of flare do hydraulic brakes use?
Hydraulic brakes use a double flare or a bubble flare.
Why are brake line compression fittings prone to failure?
Unfortunately, using brake line compression fittings presents multiple problems. Because your brake system creates a substantial amount of pressure, the compression fittings are prone to failure. In addition, compression fittings are known to leak when used on brake lines, ...
What is a compression fitting for brake line?
Despite this, many people choose to try brake line compression fittings for line repairs. Compression fittings are used to join two pieces of brake line together. This form of repair is common because of the idea that the fitting prevents leakage. The compression fitting is comprised of a nut and a ferrule.
What is the brake pedal?
The brake pedal, also called a lever, is contained inside the vehicle and is used by the driver to begin the braking process. The pushrod, or actuating rod, engages with the pistons in the master cylinder assembly. The brake fluid is designed to experience little or no compression which translates into a rise in pressure throughout the entire system. This pressure equalizes through the hydraulic lines causing the pistons to place pressure on the brake pads. The rotor–a component connected to the wheels–begins to receive increasing pressure from the brake pads and lessens the speed with which the wheels turn.
What percentage of accidents are caused by brake failure?
Even though only 5 percent of accidents in the United States are attributed to brake failure, the possibility exists, especially when someone performs faulty repairs. Brake line compression fittings are a controversial repair component and can lead to failure in the brake system.
What is the rotor on a car?
The rotor–a component connected to the wheels–begins to receive increasing pressure from the brake pads and lessens the speed with which the wheels turn. It is important to know that the braking system is considered “closed,” which means that fluid does not escape the system or evaporate over time.
How much does it cost to replace brake lines?
Replacing your brake lines can cost several hundred dollars, at minimum, which can create a strain on your budget. Consequently, many people choose to use temporary replacement techniques to manage car repair hurdles. For example, some people choose to use a rear view mirror kit to attach a separated rear view mirror.
What does closed braking mean?
It is important to know that the braking system is considered “closed,” which means that fluid does not escape the system or evaporate over time.

Can you drive a farmer bodge together?
if you farmer bodge together something so [censored], it should just be to drive it to the mechanic or to the parts store for a whole new brake line . on top of that, you should not let anyone other than yourself drive it while it is like that.
What is a compression assembly?
It is a metal object, which connects one component of the coupling to another, usually some type of pipe, to create a waterproof seal. In particular, this accessory usually connects two parts of the brake line and prevents leakage. Compression assembly consists of a nut and a sleeve. When placed on the brake cord, the fitting makes a tight connection.
Is it a good idea to have accessories in the long run?
Remember that while accessories offer an inexpensive alternative, they are not a long-term option. An accident will do much greater financial and ethical damage in the long run.
Do brake line compression fittings work?
Brake line compression fittings work well in certain situations. If the vehicle is for off-road use or restoration, you can use substandard accessories for temporary repairs. In addition, public transport or expressway vehicles must use DOT-approved products.
