Whether you are repairing a car or building a classic vehicle, knowing how to install brake lines can be a useful skill to have. By following a few steps, you will find that it is a task that doesn’t need the services of a mechanic in order to complete it.
In order to install the brake lines effectively, you must have access to the relevant area of the vehicle. Position the vehicle jacks beneath the end of the vehicle that you intend to work on and operate the lever to lift the vehicle enough to allow you to remove the tire. This will allow you to take out the lug nuts so that can get access to the braking system. If they prove stiff, spray some lubricating oil onto the fasteners to help get them moving.

ARRANGE NEW BRAKES
You must decide how many brake lines that you want to install. It is prudent to do them two at a time so that they wear evenly and you can easily track when they need to be changed. Ensure that the brake line you use is appropriate for the vehicle as well as for the front or rear tires where you intend to fit them. Do this by reading the instructions given with the brakes.
REMOVE OLD BRAKES
It may be important to remove the old brake lines before you are able to fit new ones. Before undertaking this task, use a rag to carefully wipe around the connectors and the brake line to ensure that there is no dirt present which may find its way into the braking system. Undo the connection by fitting two wrenches around the connectors that are fitted midway along the brake line. Where the brake line is fitted with connectors only at each end, only one wrench will be needed for each end. Keep a rag to hand to catch the flow of brake fluid that will be generated by the loosening of the connectors.
The process of installing a brake line is done by reversing the removal process and can be done by hand. After making sure the brake line is not kinked, twisted or snagged on any other component of the car, position the two sides of the connector so that they are directly adjacent to one another. Thread them together by hand as tighten them as much as you are able before completing the process with wrenches.
After finishing the installation process, you will need to bleed the brakes. You can then check to ensure that there are no leaks from any of the parts while the car is still raised with the vehicle jacks. Do this by depressing the brake pedal for approximately 30 seconds and tighten any fasteners where leaks are observed.
