Weekly Info- Did You Know??? Brake Fluid

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.
