5 Common Reasons Brakes Feel Spongy
There are 5 fairly common reasons brakes will being to feel spongy. While gearheads and regular motorists love to talk about acceleration stopping power many times is forgotten. Getting to 100 is fun but it’s less fun to think about emergency braking situations. If you’ve noticed diminished brake strength or a spongy feeling make sure you get a brake inspection to ensure your safety and the safety of other motorists.
1. Damaged Brake Lines
Brake lines can become damaged or start to rust if the vehicle has been driven near saltwater or in areas that spread salt on snow. These conditions cause the brake lines to become fragile, start leaking, or completely break. If you’ve been involved in an auto collision the brake lines could also be compromised.
2. Air In Brake Lines
If your brake fluid is low or brake pads are worn down air can be drawn into your brake system. Air is more compressible than hydraulic fluid and will cause a spongy feeling in your brakes. This is by far the most common cause of spongy feeling brakes and can be repaired by brake repair technicians. Read more about air in brake lines.
3. Worn Brake Cylinders
Your car’s master cylinder distributes the pressure of the hydraulic fluid in your brake system. When you apply the brake the master cylinder pushes the hydraulic fluid so the brake pads are pressed against the discs and the vehicle slows. If the master cylinder is worn it might have leaks or be broken. This is a common potential cause of spongy brakes.
4. Damaged Brake Calipers
If your car is pulling to one side when you apply the brakes, you could have damaged calipers. As you drive and apply your brakes intense heat is created via friction. In some cases this damage causes a screeching sound as you apply the brakes. This high head does cause wear on components such as the calipers and discs.
5. Low Or Old Brake Fluid
Brake fluid by nature absorbs water. This means over time the brake fluid has excessive moisture which can compromise your brake lines with rust. If you bad brake fluid or not enough brake fluid it will cause your brakes to feel soft or spongy. It’s important to get them checked out and new fluid added when necessary.
