How should you perform a hydraulic brake check?

Performing a hydraulic brake check is essential for ensuring that your vehicle's braking system is functioning properly. The recommended approach involves pumping the brake pedal three times and then holding it for five seconds.

This method is effective because it allows the driver to assess the feel of the brake pedal under normal operating conditions. Pumping the pedal builds pressure in the hydraulic system, and holding it for five seconds helps check for any noticeable loss of pressure. If the pedal sinks to the floor or shows a significant decrease in pressure, it may indicate a hydraulic leak or a malfunction within the brake system. This step is critical for safety, ensuring that the vehicle will be able to stop effectively when needed.

In contrast, while pumping the pedal two or four times might seem useful, it does not provide the same level of assessment for detecting issues in the braking system. Similarly, pressing the pedal once and releasing does not build sufficient pressure or provide the necessary feedback to evaluate the brake's effectiveness comprehensively. Hence, the approach of pumping three times and holding for five seconds is the most thorough method to ensure your hydraulic brakes are in optimal working condition.
