Introduction
A brake pedal that feels soft, spongy, or sinks toward the floor is a serious safety concern. It usually indicates a problem within the hydraulic braking system.
Air in the Brake Lines
One of the most common causes is air trapped inside the brake lines.
Brake systems rely on hydraulic pressure, and air pockets reduce the effectiveness of that pressure.
Brake Fluid Leak
Low brake fluid caused by a leak can also make the brake pedal feel soft.
Leaks can occur in:
- Brake lines
- Brake calipers
- Master cylinder
Failing Master Cylinder
The master cylinder is responsible for generating hydraulic pressure in the braking system. If it begins to fail, the brake pedal may slowly sink to the floor.
Conclusion
A spongy brake pedal should be inspected immediately because it can reduce your vehicle’s ability to stop safely.
