How are brake line issues diagnosed?

When inspecting the brakes, the technician will look for cracking in the brake line. When the brakes are applied, the brake line will swell under hydraulic pressure if they're going bad. Another sign is if the brake line is leaking brake fluid.

How is a brake line replaced?

Disconnecting the brake line, and connecting the new line takes just a few moments, but the system must be flushed to remove any contaminants or debris left behind by the old brake line. The system then must be bled of air.

RepairPal recommendations for brake line issues

If a brake line fails due to deterioration, the others will probably fail soon afterwards. Replacing them all at once may prevent a future visit to a repair facility. At the very least, the other brake lines should be inspected when replacing one of them. We recommend using high-quality or OEM brake lines.

The metal brake lines on a vehicle rarely need service, but they can become corroded if the brake fluid is not changed on schedule. Salty road conditions can also cause exterior rust that can lead to failure.

Can I replace the brake hose myself?

The braking system can be maintained by a DIYer with plenty of knowledge of hydraulic systems. But if you don't have deep knowledge of braking systems, this repair should be left to a professional, as your safety depends on it.
