Why are Brake Lines Coiled?

In many cars, the brake lines are coiled. This is because it allows for a smoother flow of fluid from the master cylinder to each wheel.

The smoothness of this process ensures that maximum stopping power can be applied to all four wheels at once, instead of just one or two at a time as would happen with uncoiled brake lines.

Coiling also helps prevent damage to the brake system by avoiding kinks and bends in the line.

Here are some reasons why brake lines are coiled in cars.

3 Reasons why brake lines are coiled

  • Coiling reduces the chance of kinked or damaged brake lines, which can lead to uneven braking and loss of safety.
  • It allows for uniformity in pressure throughout the entire hydraulic system at all points along the line, which leads to less chance of uneven application of brakes.
  • Coiled brake lines allow for better management and control over the flow of fluid from one part of a complete braking system to another; this maximizes effectiveness while minimizing complexity and unnecessary cost.

How brake lines work?

Brake lines are the part of your brake system that connects the master cylinder to each wheel. The most common material used for brake line is rubber, which acts as both a protector and an insulator against heat, pressure, and vibration. Some systems use steel or stainless steel pipes; these can be found in many modern passenger vehicles, trucks, SUVs, and vans.

How are Brake Lines Coiled?

Coiling the brake line is really an easy process. You first start by identifying where you will be mounting your brake line and then cut it to length.

Be sure that you use a pipe bender when coiling. When bending, be mindful of how tight your bend radius should be — usually any tighter than 10 inches will lead to kinks and serious damage due to lack of flexibility.

Once done coiling and maintaining a proper radius, secure each end of the hose with metal clamps, and then secure the hoses with bolts or adhesive.

Where are brake lines coiled?

Brake lines are coiled in multiple locations including

  • At the end of a front axle and then under the car, which is good for smooth and even braking;
  • Near the rear axle;
  • Near the master cylinder;
  • Outside the vehicle’s body to achieve increased flexibility.


Although brake lines are coiled for many reasons, it primarily helps with ensuring a smooth flow of fluid along the lines.

It also helps with avoiding damage to the brake system by preventing kinks in the lines.

And lastly, coiling allows for uniformity in pressure through the entire hydraulic system so there is less chance of uneven application of brakes.
