How to determine if the brake lines need to be replaced?

To determine if brake lines need replacement, consider the following:

1. First, check the brake line connectors. If the connectors are rusted, especially if they are severely rusted and may break, they must be replaced.

2. Also check the brake line body. A bulge in the line can be dangerous during continuous braking or repeated hard braking.

Cracks in the line body are also a major problem, as rubber has a lifespan; even unused brake lines can crack.

Scratches on the exterior are also a concern, as they can easily rub against the line during driving, leading to leaks.

3. Leaks from the line body are extremely dangerous and require immediate replacement.

4. In terms of lifespan, under normal driving conditions, brake lines typically last 60,000 kilometers. It's recommended to replace the entire system every 3 years or 60,000 kilometers. However, this isn't the only standard; driving conditions and driving skill also play a role. Driving in harsh conditions or frequent hard braking will shorten the lifespan.

5. The feel of the brake pedal and braking distance can also help determine this. When brake lines exceed their maintenance interval, braking performance will deteriorate, requiring deeper pressure on the brake pedal to achieve the same effect as a light press. The initial braking effect will be significantly weaker, at which point replacement should be considered.

The condition of the brake lines should be checked during each maintenance service, and any abnormalities should be addressed immediately.

In short, proper driving techniques can extend the life of brake lines, such as maintaining full concentration at all times, releasing the accelerator early to slow down, and deciding whether to apply the brakes based on the situation. However, if any of the above-mentioned brake line problems are discovered, they must be replaced promptly to ensure driving safety.
