Where to Check Brake Fluid?

Open the front hood, and you can check the brake fluid level using the scale lines and ruler on the oil reservoir. Below are the methods for selecting brake fluid: 1. The seals in the braking system are rubber components. Prolonged immersion in brake fluid can cause chemical changes, leading to expansion or contraction of the rubber, which affects braking performance. Therefore, choose brake fluid that is highly compatible with rubber. 2. High-temperature performance refers to the brake fluid's ability to resist vapor lock at high temperatures, measured by the 'equilibrium reflux boiling point' indicator. The higher the equilibrium reflux boiling point of the brake fluid, the better its high-temperature performance and the higher its quality grade. 3. The flow performance of brake fluid at low temperatures is observed by its kinematic viscosity at 40°C. If the viscosity of the brake fluid is too high at this temperature, it can affect the transmission of braking force.
As a driver with over a decade of experience, I frequently check my brake fluid level myself. Simply put, you need to open the hood and locate a small plastic reservoir near the windshield in the engine bay, marked with BRAKE FLUID. It's usually translucent so you can directly see the fluid level inside. Ideally, the fluid should be between the MIN and MAX marks. If you notice the level is low, it might indicate a leak in the system, and you should visit a repair shop immediately, as failing brakes are extremely dangerous. I recommend checking every three months, especially for older cars, to prevent minor issues from escalating. Also, when adding brake fluid, avoid mixing different types—always refer to your owner's manual for the correct specification.
When it comes to checking brake fluid level, I'll share some practical tips. After starting the vehicle, turn off the engine and wait for it to cool before opening the hood. You'll typically find a cylindrical plastic reservoir labeled 'Brake Fluid' on either the left or right side in most car models. Use a flashlight to check if the fluid level is between the marked lines. If you notice soft brakes or longer pedal travel while driving, it likely indicates low fluid level requiring prompt top-up or inspection. I consider this quite important since the entire braking system relies on this hydraulic fluid to prevent accidents, and maintenance costs are relatively low. Those with good DIY skills can easily handle this themselves.
