Causes of Brake Pedal Going to the Floor When Car Is Running
The brake pedal going to the floor when your car is running can be caused by a variety of factors. Some of the most common causes include:
Low Brake Fluid Level
One of the most common causes of the brake pedal going to the floor is a low brake fluid level. When the brake fluid level is low, it can cause the brake pedal to feel spongy or soft, making it difficult to stop the vehicle. This is often caused by a leak in the brake system or worn-out brake pads.
Here are some signs that your brake fluid level may be low:
- The brake pedal feels soft or spongy when you press it.
