* Location of the leak: A leak in an easily accessible line is cheaper to fix than one deep within the chassis or near the master cylinder. Hard-to-reach areas mean more labor time.
* Extent of the damage: A small hole might be repairable with a compression sleeve or specialized sealant, while a severely rusted or damaged section might require replacing a whole section of line or even the entire brake line.
* Labor rates: Mechanic labor rates vary widely by location and shop. Independent shops are generally cheaper than dealerships.
* Parts cost: The cost of brake lines, fittings, and brake fluid will also add to the overall price. Finding used parts might be an option to lower costs but carries some risk.
Rough Estimate: You could reasonably expect to pay anywhere from $100 to $500 or more for this repair. The lower end would likely be for a minor leak in an easily accessible location that only requires a simple repair, while the higher end covers more extensive damage requiring significant line replacement. If the master cylinder is also damaged, the cost could increase substantially.
Recommendation: Get at least two or three quotes from reputable mechanics in your area before committing to a repair. Explain the situation clearly and ask for a detailed breakdown of the cost (parts and labor). Safety is paramount, so don't drive the car with a brake fluid leak; it's a serious safety hazard.
