If you’ve ever popped the hood and stared at your brake fluid reservoir wondering whether your car should be running while topping it off, no estas solo. This question is more common than you think—especially for DIYers and new drivers. Afortunadamente, you’re about to get a complete answer from every angle. Whether you’re troubleshooting low brake fluid or just doing routine maintenance, this guide will walk you through exactly what to do.

No, the Car Should No Be Running When Adding Brake Fluid

The car engine should always be apagado when adding brake fluid. There are several reasons for this:

• Seguridad ante todo: With the engine off, you minimize the risk of moving parts causing injury or an electrical issue occurring while you’re working under the hood.

• Brake Fluid Stability: Brake fluid is highly sensitive to heat and moisture. Running the engine creates heat, which can increase the risk of contamination or air getting into the system.

• Accurate Level Reading: The brake fluid reservoir is best checked and filled when the system is at rest—engine off, car on a flat surface—so the reading isn’t skewed.

Why Brake Fluid Is So Important

Brake fluid is not just another fluid—it’s the lifeline of your vehicle’s braking system. It transfers the force from your foot on the brake pedal directly to the brake calipers, helping your car stop efficiently and safely.

• During regular maintenance (every oil change or ~3 months)

• si tu luz de advertencia de freno viene

• si el brake pedal feels soft or spongy

• After you notice a leak near the wheels or under the hood

If the fluid level is below the “MÍNIMO” line on the reservoir, it’s time to add more.
