What is the procedure for testing hydraulic brakes for leaks?

To test hydraulic brakes for leaks, the procedure involves pumping the brake pedal several times and then holding it. By pumping the brake pedal three times and holding it for five seconds, you can check for any drop in the pedal position, which would indicate a potential leak in the hydraulic system. If the pedal sinks, it signifies that the brake fluid is leaking, which compromises the braking system's effectiveness.

This method is effective because it puts the hydraulic system under simulated pressure and allows the driver to observe the performance of the brake pedal over a brief period. This testing is crucial for maintaining safe operating conditions in a vehicle, as any defect within the hydraulic brake system can lead to decreased braking ability, posing a significant risk on the road.
