How Do You Replace Brake Lines?

To replace a brake line, remove the wheel, and loosen the connection between the rubber part of the line and its metal fitting with two open-end wrenches. Attach and tighten the new line the same way. Fill the reservoir with brake fluid, and bleed the system afterward.

  1. Loosen the lug nuts

    Loosen each lug nut on the wheel associated with the brake line you want to change.

  2. Raise the car

    Lift one end of the car with a jack, and support the car on a jack stand. Repeat with the remaining three corners of the car.

  3. Remove the wheel

    Remove each lug nut completely, and remove the wheel.

  4. Loosen the brake line connection

    Locate the spot where the rubber hose of the brake line connects to a metal fitting. Place a wrench on either side of the fitting, and loosen it.

  5. Remove the line

    Place a rag underneath the line, and remove it.

  6. Attach the new brake line

    Attach the new line to the fitting, and tighten it by hand. Tighten the fitting all the way with two wrenches.

  7. Repeat with the other line

    To ensure the proper performance of your brake system, replace the other brake line as well.
