A good rule to follow is to have your mechanic check your brakes and brake fluid during every oil change. They’ll be able to give you the best feedback on how your brakes are working and if they need new fluid. Most drivers find they need to change their brake fluid every four to five years.
That means when you press the brake pedal you are pressurizing some fluid lines. Those lines run out to the wheels where the added pressure forces the pads against the rotors or drums. If that fluid is low or missing you will end up with nothing but air in those lines.
Brake fluid (Light yellow to dark brown)
Brake fluid starts clear to light yellow and becomes darker as it ages. It smells like fish oil. You can find this leak in the middle or rear wheels. Brake fluids are slippery than engine oil.
One of the most common reasons for your brakes touching the floor would be an issue with your brake fluid. Your fluid being low or air reaching the brake line will prevent the fluid from flowing properly, resulting in a spongy pedal. A bad brake booster is another common cause for a malfunctioning pedal.
After flushing all four lines with clean fluid, the fluid in your whole brake system will be new and the fluid in your reservoir will be clean and new as well. Step 9: Pump your brake pedal. With everything re-assembled, pump the brake pedal firmly 5 times.
