Don't Grind My Gears

“Spongy brakes” is one of those phrases people use to describe a feeling, not a diagnosis. The pedal feels soft, it travels farther than usual, and the car stops with less confidence. The important part is this. Different causes feel similar, and the right fix depends on which type of soft you are dealing with.

Soft pedal at low speeds usually means compressibility

If the pedal feels squishy even during gentle stops, you are often dealing with air in the system, old fluid that has absorbed moisture, or a hydraulic issue that is letting pressure bleed off. Brake fluid is designed to transmit force, and anything that makes it compressible makes the pedal feel wrong.

A proper brake fluid flush can genuinely change a car’s personality if the fluid is old. If there is air, bleeding the system is the fix, but you still want to understand why air got in, because it usually has a reason.

Soft pedal after repeated hard stops is often heat

This is where people say “fade.” You stop hard a few times and the pedal either goes long or the car stops with less bite. Heat changes everything. Pads can lose friction when overheated, and old fluid can boil, which creates vapor and that vapor compresses. The pedal feels wrong, and it gets worse as the system gets hotter.

The real goal is consistency

Great brakes feel the same on the first stop and the fifth. If your car changes behavior once the brakes are warm, that is a clue. Solve the clue, not the vibe.
