Did You Know:
Your car’s braking system is the only thing between you and whatever you are approaching. Also,
without proper brake fluid in it, your car will not stop. This is exactly why routine brake maintenance is
so important to your safety.
WHAT IS BRAKE FLUID
Brake fluid is a type of hydraulic fluid used in hydraulic braking systems to transfer force into pressure,
bringing the vehicle to a complete stop when the brakes are pushed in. Similar to your engine, modern
braking systems require routine flushes and replacements of the fluid at designated intervals. Brake
fluid is one of the most critical fluids in your car.
BRAKE FLUID HELPS YOUR CAR STOP
When you press your foot on your brake pedal as you approach a red light, a rod forces a piston into the
cylinder, creating pressure throughout the entire hydraulic system. This newly added pressure is
distributed throughout the system by forcing brake fluid throughout the brake lines into the caliper
pistons. The pistons then apply the force to your brake pads, applying force to the spinning tire rotors
and slowing down the entire vehicle.
BRAKE FLUID PREVENTS RUST AND CORROSION
The majority of brake fluids are hygroscopic, meaning that it is great at absorbing moisture. This means
that not only does it lubricate all the moving parts and components of your car’s braking system, but the
fluid also soaks up any moisture in your braking system to prevent corrosion and rust.
WHEN DO I NEED TO CHANGE MY BRAKE FLUID
At the end of the day, the frequency of your brake fluid changes depends on your driving habits and
braking patterns. Things like constant stop-and-go traffic, sudden braking, and increased mileage can all
contribute to needing brake fluid service sooner than later.
Be on the lookout for these signs you need to have your brake fluid replaced:
ABS Light Illuminates;
Changes in brake pedal;
Strong burning smell and loud sounds; and
Ineffective braking.
