Here are a few of the signs that indicate that your brake line may be going bad.

This can be due to a number of problems: a leak in a brake line, a loss of pressure within the master cylinder itself due to a failed seal, or air being introduced into the braking system. Your first reaction to encountering spongy brakes should be to rapidly pump the brake pedal with your foot.

Diagnosing a bad brake master cylinder

• No Brakes. The most obvious symptom of a bad master cylinder is brakes that don’t work at all.
• Poor Braking. Since usually only the brakes at the front or back will go out at a time, you will likely notice your car doesn’t stop as well as it should.
• Inconsistent Brakes.
• Leaks.

• You Are Leaking Brake Fluid.
• Your Brake Fluid Light Comes On.
• You Can Push Your Brake Pedal to the Ground.
• The Brake Lines Have Visible Moisture Signs or Corrosion on Them.

The most common of these is natural wear and tear. As your brake pads age over time, they will naturally lose their ability to stop the vehicle. As a general rule of thumb, most brake pads need to be changed once every 25,000-50,000 miles. The second most common cause of brake failure is a malfunctioning brake booster.

One of the more common causes for the brake pedal going to the floor is a loss of brake fluid. When you’re out of brake fluid, your brakes simply won’t work. Another possible cause is a bad brake master cylinder. The master cylinder is where brake fluid gets compressed.

Steps to Follow on How to Get the Air Out of Brake Lines

1. Step 1: Attach a Plastic Tube. Check the bleeder and gain access to it.
2. Step 2: Recycle Old Brake Fluid. In this step, wear an eye goggle and a dust mask to be on the safer side.
3. Step 3: Use New Brake Fluid.
4. Step 4: Check Everything.
5. Step 5: The Final Part.
