Brake line washers: safe to reuse?

[Gas Man]

Do you mean the copper washers?

Can re-use, as long as it looks good. You can buy new ones at the auto store.

You can also retemper them by hitting them with a torch. Can't remember why but it does something to them.

For banjo bolts in brake systems they aren't just regular washers. They are copper. Regular washer would leak like a siv.
