Hello recently lost all brake fluid from master cylinder. Looked under found rusty brake line where fluid was leaking when brake was applied. Other two brake lines look solid, is this brake line sold pre-bent? If so from where? How hard is install? Are special tools required? Do the brake lines need to be bled after replacement? If so how? Attached are pictures...any comments, tips would be helpful. Line runs up driver side to master cylinder. Is this considered easy backyard job or mechanic? Thank you very much.
