When you step on the Brake pedal and if you feel that the brake pedal is soft and spongy it means there is a problem with your brake. Do you know what can cause a soft spongy brake pedal? A soft spongy brake pedal is a brake pedal which when the brake pedal is depressed it feels soft like a sponge.

Usually, the normal brake pedal is firm when you press your foot on it when you apply the brake. During braking when you press your foot on the brake pedal the brake fluid will be forced through the brake lines going into the brakes to make the car stop. If the brake is properly functioning without any problem at all, the brake pedal feels solid and firm because the brake fluid will be compressed.

If the brake pedal is soft or somewhat spongy then it means that there is a presence of air in the brake lines. The possible reason why air gets into the brake lines is when there is a work done on the brakes the brake is not properly bleed. Every time a work is done on the brake line the brake should be bled. Also, another reason is when there is a leak somewhere in the brake lines which allows the air to get inside the brake lines.
