Why does my car brake pedal feel soft?
Air in the brake line(s) is the most common cause of a soft/spongy brake pedal. If air gets into the brake lines, it can prevent brake fluid from flowing properly, causing the brake pedal to feel spongy or soft. If the brakes are soft or spongy, this is a good time to change or flush the brake fluid.
Are brake pedals supposed to be loose?
If your car’s brake pedal feels loose and wobbly, and you find yourself needing to push down incredibly hard on it in order to stop your car, you have an emergency situation on your hands. A loose brake pedal is typically caused by an insufficient amount of brake fluid without your car’s brake lines or master cylinder.

How can I tell if my master cylinder is bad?
When a master cylinder begins to fail, sometimes the brakes will feel fine one second and lose braking power the next. If fluid is leaking past the seals inside the cylinder, the pedal may feel firm for a moment but won’t hold steady; it’ll feel spongy and keep sinking towards the floor.
Why does my brake pedal move back and forth?
The smooth surface pressed against the uneven surface isn’t ideal for your braking system and often causes a rocking or wobbling motion when the brakes are applied. If both the brake pads and rotors have too much or uneven wear, the effects can be even worse.
Do brake pads affect pedal feel?
Your brake pedal can also tell you about the condition of your brakes. If you feel grinding, your brake pads are worn down and need replacing. If your pedal feels shaky, the rotors are warped. In both cases, you’ll need to replace the pads and most likely rotors.
