How Do I Know My Porsche Brake Lines Have A Problem?

Brake lines are sturdy metal hard lines found in nearly all modern Porsche models. They are more or less the piping that serves your Porsche’s hydraulic braking system. The lines take brake fluid from the master cylinder all the way to the wheels via flexible brake hoses and right into wheel cylinders or brake calipers.  Many modern brake lines are made of steel, which means they can withstand exposure to harsh elements as well as high pressure. With time though, brake lines develop problems mostly because of wear and tear. This means your safety will be compromised if for one reason or another you take long to fix the problem. Before then though, lookout for any of the following signs of a faulty brake line.

Leaking Brake Fluid

This is one of the most common signs of a failing brake line. You’ll notice that the leaks happen mainly when you apply brakes. This is often a sign that the brake lines have succumbed to wear and tear and need to be replaced.  Be keen on the brake warning light at this stage. It will turn on when brake pad wear sensors are activated. The lights also come on when brake fluid drops below a specific level.

Mushy Brake Pedal

This is yet another common symptom associated with brake line failure. You’ll notice failure is imminent once the brake pedal becomes soft and mushy. This happens because of leaking which compromises pressure.  It is a serious problem because the brake eventually becomes less responsive.

Grinding Sound When Applying Brakes

The grinding sound you hear each time you apply brakes could mean a number of things. It could be that some rock or gravel got stuck in the caliper unit. It could also be a servicing issue. That is, you may have driven your car for way too long without taking it for servicing.  Whatever the case, this is never a good sign.

Note that grinding sounds could also be an indicator or poor lubrication. This is especially in Porsche models that use read drum brakes. The noise in this case means that the brake shoe is scrapping on metal contact points such as the backing plate. Note too that the brake shoe is the only component designed to press on the rotor so as to slow the vehicle. Once it gets compromised, your safety becomes compromised as well. The solution here is not just to lubricate the problematic component but to replace any other component that may have been affected by poor lubrication.

Point to Note

You do not have to wait for any of the aforementioned signs so as to take action. Pay attention even to minor braking system issues that do not seem normal. Like already mentioned, the brake is a safety component. It is the last component anyone would want to ignore. Your best bet is to take your Porsche for regular servicing. Be sure to take your car to a licensed repair center.  Be sure to also use original OEM replacement parts.
