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.
- Loosen the lug nuts
Loosen each lug nut on the wheel associated with the brake line you want to change.
- 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.
- Remove the wheel
Remove each lug nut completely, and remove the wheel.
- 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.
- Remove the line
Place a rag underneath the line, and remove it.
- 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.
- Repeat with the other line
To ensure the proper performance of your brake system, replace the other brake line as well.
