How Often Should I Replace My Porsche Brake Lines?

Brake lines are often overlooked during usual brake repairs. This is of course, a bad habit because there is a direct link between the condition of your car’s brake lines and your safety. There are several reasons why you should replace them. However, three reasons stand out the most when it comes to Porsche models – breakage, repair and maintenance. You do not have to wait until the brake lines are worn out or damaged for you to replace them. The best you can do is to have your Porsche inspected at least once a month. It’ll then be easy for your mechanic to determine when and even how often you should replace your brake lines.


It is strange how brake line replacement due to maintenance is the most overlooked and ignored reason. Old brake lines will with time, cause costly brake issues. Take rust for instance. It is easy to spot it. You should therefore replace your brake lines the first time you spot traces of rust before the small rusty patch spreads. Note too that rust can easily contaminate brake fluid. This can result to torn rubber seals in the calipers or in the brake cylinder.

There is also moisture and heat which are just as bad as rust. Rubber hoses actually deteriorate because of heat and moisture. This deterioration always results to sudden brake failure or collapsing. The hoses may also come apart internally and in the process, contaminate brake fluid with tiny rubber particles. All these explain why brake line maintenance is vital. You get to notice any of the aforementioned hitches and fix them on time before things get out of hand.


Brake lines can break down on their own completely. The most likely culprit in such cases is wear and tear. It could also be as a result of poor maintenance. Whatever the case, you have no choice but to repair broken break lines. That is because one a brake line breaks, there is literally no pressure in the brake system. This easily leads to brake failure, which can be devastating while driving at a high speed. Be sure to inspect all rubber hoses for large cracks or small pin hoses during brake line repair. These two are red flags that the lines are about to break. Remember to also inspect the hard metal line too. Like rubber hoses, they also get small holes. Replace the metal line as well as the rubber hoses and the brake lines as soon as you notice holes.


There is a thin line between repairing and replacement when it comes to brake lines. Replace what cannot be repaired is the thumb rule. That is where factors such as brake line collapse come into the picture. Once the lines collapse, there is nothing you can do to repair them. Your best bet is to replace them. The collapse could be from impact. It could also be as a result of worn out rubber lines. Whatever the cause, replacing the lines is best solution.

Note that the collapse is usually preceded by signs such as the car pulling to one side each time you brake. Note too that you may have a hard time diagnosing a collapsed rubber line on your own. That’s because you cannot see the inner part of the line. A mechanic should be able to help you note the signs and fix the problem altogether.
