How do you fix a rusted brake line?

The brakes in my car have started squealing loudly when I drive. I hadn’t driven for a while before this, so I think they may be getting rusty. What’s the best way to fix a rusted brake line?

I’m sorry to hear about your brakes! I’m sure the squealing is annoying. While it is possible to fix a rusted brake line yourself, unless you are comfortable with advance
car maintenance
, you should only have a trusted mechanic fix your rusted brake line.
Here are the steps a mechanic will usually take to fix a rusted brake line:
  1. Inspect line for rust. They will replace the brake line if there is any damage beyond surface discoloration.
  2. Remove fittings from the brake line. If the entire line needs replacing, a mechanic will remove the fittings. Otherwise, the mechanic will just remove the damaged section.
  3. Shape the new line. The mechanic will create bends in the new brake line to match your old one for the best fit.
  4. They’ll cut off any excess for proper fitting and install the fitting into the brake system.
  5. Then, they’ll make a flare to keep everything in place.
Keeping up with your car’s brake maintenance is key to saving on repair costs.
