A stuck brake line can be a major headache for any car owner. Not only is it dangerous to drive with a brake line that is not functioning properly, but it can also be difficult and expensive to fix. If you find yourself in this situation, don’t panic. There are a few things you can do to try to get the stuck brake line off yourself.

Safety First

Before you begin, it is important to take some safety precautions. Make sure that your car is parked on a level surface and that the parking brake is engaged. You should also wear safety glasses and gloves to protect yourself from any flying debris.

Tools You Will Need

To get a stuck brake line off, you will need the following tools:

  • A flare nut wrench
  • A penetrating oil
  • A hammer
  • A punch
  • A new brake line

Step-by-Step Instructions

1. Locate the stuck brake line. The brake line is a metal tube that runs from the master cylinder to the brake calipers. It is usually made of steel or copper.
2. Apply penetrating oil to the flare nut. The flare nut is the nut that connects the brake line to the caliper. Apply a generous amount of penetrating oil to the flare nut and let it sit for a few minutes.
3. Use a flare nut wrench to loosen the flare nut. Place the flare nut wrench on the flare nut and turn it counterclockwise. If the flare nut is stuck, you may need to use a hammer and punch to loosen it.
4. Remove the brake line. Once the flare nut is loose, you can remove the brake line. Be careful not to damage the brake line or the caliper.
5. Install the new brake line. Insert the new brake line into the caliper and tighten the flare nut. Be sure to tighten the flare nut to the manufacturer’s specifications.
6. Bleed the brakes. Once the new brake line is installed, you need to bleed the brakes to remove any air from the system.

Tips

  • If you are having trouble getting the flare nut loose, you can try using a heat gun to heat up the nut. This will help to loosen the rust and make it easier to remove.
  • If the brake line is badly rusted, you may need to cut it off and replace it with a new one.
  • It is important to use the correct size flare nut wrench. Using the wrong size wrench can damage the flare nut.

Troubleshooting

  • The flare nut is stripped. If the flare nut is stripped, you will need to replace it.
  • The brake line is damaged. If the brake line is damaged, you will need to replace it.
  • The brakes are not bleeding properly. If the brakes are not bleeding properly, there may be air in the system. You will need to bleed the brakes again to remove the air.

When to Call a Mechanic

If you are unable to get the stuck brake line off yourself, you should call a mechanic. A mechanic will have the tools and experience to safely remove the stuck brake line and replace it with a new one.
