What does it mean when your brakes go soft all at once?
This is especially true if your brakes go soft all at once, without any advance warning. Also known as spongy brakes, this brake pedal feel is almost always an indication of a problem with your vehicle’s brake fluid system, and it has several potential causes.
What are the problems with soft brake pedals?
1. Soft Brake Pedal A soft brake pedal is a MAJOR brake issue. If your brake pedal feels squishy, “like stepping on a plum,” and won’t stop on the way down unless you pump it, or the brake pedal sinks to the floor with little or no resistance, you have a dangerous situation and should NOT drive any further!
What to do when your brake pads go to the floor?
If the reservoir is empty then either the front or rear brake pads need to be replaced or their is a leak somewhere in the brake system. Inspect for Brake System Leaks: Using a flashlight check the rear of the master cylinder where it bolts to the brake booster.

At this point the brake warning light may or may not be on. A Bad Brake Master Cylinder: A master cylinder had two sets of internal seals which naturally wear from usage and when they fail cause the fluid which is normally pressurized inside the master to bypass backward into the brake master’s fluid reservoir or leak out from the rear of the unit.

What to do when your brake pedal goes to floor?
The first thing to check when your brake pedal goes to floor is to raise the hood and check the brake master cylinder’s reservoir. If the reservoir is empty or the brake fluid level is low, there is most likely a leak somewhere in the brake system.
What causes a soft and spongy brake pedal?
Corrosion inside that wheel cylinder can cause brake fluid to leak resulting in a loss of hydraulic pressure. This leads to a low or soft/spongy brake pedal. If the vehicle has a rear brake drum/shoe and pumping the brake pedal improves the brake pedal, the rear shoes may be out of adjustment.
What to do if your car brake fluid is spongy?
If the brakes are soft or spongy, this is a good time to change or flush the brake fluid. Flushing the brake fluid, commonly called bleeding the brakes, gets rid of the air. (Bleeding the brakes uses fluid to push air out of the brake system.) Over time, brake fluid absorbs moisture.
