Break fluid can be an easy part of routine maintenance to forget about. However, it plays an important part in the brake system on your vehicle, and forgetting about it for too long can be dangerous. It’s best to have your fluid flushed and replaced at a maximum of every 30,000 miles.
Below are a few key signs your brake fluid might need to be replaced.
In order to check your brake fluid, you must locate the reservoir. The location depends on the type of car. The brake booster is on the driver’s side, usually near the firewall. Right in front of that, on top of and connected to the brake master cylinder, is the brake fluid reservoir. It’s usually a plastic canister.
Older cars do not have a plastic reservoir. Usually, the master cylinder is a small metal box with a lid that you have to remove to check the level of fluid.
When you place your foot on the brake pedal, the fluid in the master cylinder travels down the brake lines to the front and back brakes. If there’s not enough brake fluid, air enters the brake lines, and your car will not stop as it should. For that reason, it’s vital to keep enough brake fluid in the reservoir.
How to Check Your Brake Fluid:
It’s best to have a professional check it however as any moisture that enters the brake fluid can cause corrosion to the hydraulic components. If moisture gets into the brake fluid even for as little as 15 minutes, the fluid is no longer useful.
Brake fluid, also called hydraulic fluid is defined as powered or moved by a fluid. It’s an uncompressed substance that transports any force applied on the brake pedal to the brake rotors on all four corners of a car. The fluid works under high temperature and pressure and your car would not stop without it even if you used force when applying the brakes.
It is recommended that you flush and replace your brake fluid periodically. For this reason, it’s because it absorbs moisture easily. Any amount of moisture causes the fluid to break down and if it becomes too saturated, it will no longer be useful. So, it’s important to protect the brake fluid to prevent it from developing any kind of moisture.
Depending on your car or truck manufacturers, most mechanics recommend that you change your brake fluid every one to two years. However, many car owners have vehicles that are more than 10 years old and haven’t replaced the brake fluid. Generally, without periodic replacement, it will increase the number of accidents because of brake failure.
