Spongy or Soft Brake Pedal
When the brake pedal feels spongy or soft, the braking system loses its effectiveness. This is a critical symptom that means your car may not stop in time.
Likely causes — most common first
Air in the Braking System
Air compresses unlike brake fluid, so the pressure from your foot is not transferred to the brake pads, making the pedal feel spongy or soft.
Brake Fluid Leak
Due to worn-out hoses, pipes, or seals, fluid leaks out, and the pressure needed for braking drops.
Master Cylinder Wear or Failure
This component creates pressure in the system. If the rubber seals inside wear out, fluid starts to bypass inside the cylinder.
Excessive Wear of Brake Pads and Discs
When the friction material is completely worn out, the pistons in the calipers need to travel further, increasing the pedal travel.
Caliper Mechanism Seizure
When the moving parts of the caliper seize due to dirt or corrosion, the braking force is unevenly distributed, causing the pedal to feel soft.
