A leaking brake line is a safety emergency. Single-line repair at a shop runs $180 to $560, depending on whether it is a flex hose or a hard line and how rusted the fittings are. Full underbody replacement on a rusted truck can hit $1,400.
Most drivers pay $220 to $420 per line for a steel hard-line section, or $150-$280 for a rubber flex hose. Full system replacement runs $700-$1,400.
A rubber flex hose at the caliper is a 30-minute job; a rusted hard line that runs the length of the vehicle is a 3-4 hour job.
Northeast and Midwest vehicles often need multiple sections replaced at once - one fitting cracks the next.
OEM steel is cheapest; NiCopp (copper-nickel) costs more but never rusts and bends easily.
Lines that run above the fuel tank or behind the subframe can require dropping major components.
Replacing the front-left line often means also bleeding the front-right - shops bill the fluid flush.
Lines that thread through the ABS block require a power-bleeder or scan tool to cycle the valves.

For most owners with basic tools and a safe place to work, this is within reach if the difficulty label says "Easy" or "Moderate." Hard and Expert jobs mean special tools, safety risk, or scan-tool requirements - usually worth paying a shop for. If you have never bled brakes, used a press, or worked under a vehicle on jack stands, start with a smaller job first.

No. A leak can fail completely under hard braking. If the pedal sinks or fluid is visible, tow the vehicle.
Steel hard lines on a rust-belt vehicle: 8-15 years. In a dry climate: 20+ years. Rubber flex hoses: 7-12 years before cracking.
Some states ban it on the road. Quality double-flare repair with NiCopp is the right fix.
Not necessarily, but if one rusted through, the others are aged similarly. Inspect before deciding.
Bleeding requires brake fluid, time at each corner, and on ABS cars a scan-tool cycle - it is a real $40-$120 task.
It can if air gets into the ABS pump. Often clears after a proper bleed; sometimes needs a scan-tool cycle.
