You cannot ignore the problem of low brake fluid. There are countless instances that the vehicle brake system saves lives from road-related accidents. Count that one instance when someone suddenly crosses the pedestrian lane when the red light switched to green light.
Or that one night you are a bit tired from work that you have to press the pedal when you felt dizzy. However, if the car starts showing the signs of low brake fluid, it can cause the brakes to not work at all.
The purpose of the brake system is to prevent accidents. It is a closed system where its effectiveness depends on the condition of its parts and the hydraulic fluid. The hydraulic fluid must run in the system sealed, shut, and free from any other forms of liquid and contaminants such as grits and air.
What does brake fluid mean and what it does? Brake fluid sometimes referred to as hydraulic fluid, is used to move the parts of a brake system. Brake fluid should reach certain standards to work effectively.
The brake fluid is stored in a tank called the master cylinder. When you press the pedal, the piston depresses the liquid in the master cylinder. It forces the fluid to travel along the pipelines or slave cylinders. These slave cylinders are paths that lead to the cylinders located
The pressure from the fluid causes the rotor to squeeze with the brake pads. Brake pads come in contact with the wheels to slow it down and eventually stop it from moving.
To put it simply, pressing the pedal pushes the brake fluid down to the mechanisms of the brake system to apply pressure to the rotor. The rotor, once it made contact with the brake pads, the wheels will stop moving.
The brake system has to sustain enough level of brake fluid to keep it working. Avoid implications when you’re not driving low with brake fluid.
Low brake fluid causes the following:
Generally, the brake fluid can last as long as the vehicle is working. Given that the entire system seals the fluid, there are no reasons that brake fluids cannot work the way it should be.
If the brake fluid is low, can I add more?
Yes. A little amount of brake will work if you cannot pump your brakes in the meantime. Drive the vehicle to mix the new fluid with the old one. Make sure that the brake fluid is the same as the old one!
Flush the brake fluid out when the brake fluid is contaminated. Replace the brake fluid at once.
Make sure the screw cap is clean. Fill it with the new brake fluid. Let it mix through driving.
Different vehicles vary on the brake fluid’s viscosity requirement.
You can check the manual or ask your service advisor which best fit for your vehicle model.
Bring your vehicle to your technician regularly. Regular maintenance saves you from more repairs. Check your brake level and signs of low brake fluid regularly. It pays to prioritize your safety. Lastly, drive safely!
