Below, we have compiled three of the most common symptoms that you can take notes of in order to identify any potential brake line issues.

Leaking Brake Fluids

This is the most commonly identifies symptom associated with brake line damages. Brake fluid may leak out of the brake lines because of weak hinges or damaged patches in the line caused by a rapid increase of pressure.

Corrosion On Brake Lines

Time is a quantity that cannot be prevented. Corrosion is common in brake lines that have been used for a very long time without being replaced. While you cannot stop the brake line from corrosion, you can slow it down by applying lubricants and oils. 

Brake Warning Lights Comes On

The most effective and convenient symptom to identify a damaged brake line is when your brake warning light flashes. The warning lights switch on when the brake pad sensors detect problems with the fluid capacity level in the brake lines.

How to Replace Brake Lines on a Chevy Silverado? 

Now that you have a basic idea of what sort of tools you are expected to work with, we can move on to the main steps of this guide. We’ve put up a list of all the actions you’ll need to take to replace your brake lines in the most efficient manner possible.

Step 1: Locate The Leak And The Fault In The brake Line

The first step that you need to cover is to find out the affected place and how much exactly of the line has been affected. If it is simply a minor leak, you can patch it up very easily. You can use a line wrench to help you out with the tracking. If your line has too many leaks, remove the master cylinder before moving on to the next step.

Step 2: Reshape the New Line

When you buy the new brake line, you won’t be able to use it as it is. Different cars are designed to house different shapes. As a result, utilize metric measurements such as micrometers and meter rules to record the required shape and bend the new line to the appropriate size. You can also utilize benders to accomplish your goal.

Step 3: Resize the line with a cut

Line cutters are used to trim the line size into position. Slide the cut line back and forth in the center of the burr till it vanishes. Finally, polish the incision using a file to make it even smoother.

Step 4: Fix Up The Flare

Now that you are done with the reshaping and cutting down the line to the appropriate size, it is time to fix the flare. First, ensure that the clamp is dry before you fit in the line to the flare. Use a file or flaring kit to help you out. Finally, tighten the clutch using a power tool to prevent the line from slipping. To improve performance, add a small amount of oil to the flare’s end.

Step 5: Install The New Brake Line

Now that we are done with the preparations, you can install the new brake lines into their appropriate place. Use a wipe or rug to clean off the dust or any dirt residues left by the old line. 

Step 6: Test To Check

Ensure that everything is running smoothly by running a controlled experiment where the air has been removed from the system. 

Can you still drive with a broken brake line?

You should never drive your car even if the leak on the brake line is minuscule. There are several reasons why we are advising you against this. We have plotted some of these problems that are associated with a broken brake line below:

Reduction in Braking Power

The first and most common problem associated with a broken brake line is the sharp decrease in brake power. You will often notice how you are unable to apply the appropriate amounts of braking force. A broken brake line is the main cause of this.


Partial problems with the brake line can cause the vehicle to jump-start. This means that when you start your car or apply the brakes, either the rear or the front brakes might show hard braking that will cause the car to jerk roughly. 

Hardening of the Brakes

Corroded brakes become extremely hard and refuse to work. As a result, you might find it hard to press on them with your feet. In extreme cases, hard brakes are the reason why people often face road accidents.  

How long does it take to replace brake lines on a Chevy Silverado?

Well, there isn’t any fixed time to quantify the length of time needed to cover the entire process. A qualified mechanic, on the other hand, can replace the brake lines on a Chevy Silverado in 1 to 2 hours.

Of course, that length of time can also differ depending on whether the mechanic is a professional or not. An amateur could take even longer than the time stated above. 

How much does it cost to replace brake lines on a Chevy Silverado?

Brake lines are expensive to replace. This is even more applicable for Chevy Silverado which are premium by nature. A typical brake line ranges between 136 to 164 USD. 

If you are hiring a professional mechanic to help you out, you will be required to pay an extra labor fee which is around 100 to 200 USD. Less professional mechanics will take as low as 50 USD in labor charges.  


It is estimated that each year, more than 1,35 million people are killed by road accidents. That is why it is vital that you take care of your car brakes and other gears in order to avoid any potential accidents that could end up killing you.
