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
