Question

why are hydraulic brakes less effective if there is air in the liquid​

Answer 1

Answer:

When in the line they do not transmit the force instead they are compressed. The result is that the brakes feel spongy. The air is compressing and absorbing some of the force. Causes soft brake pedal and less effective stopping (increased distance).

Explanation - The brake system is hydraulic, which means it uses high pressure from the brake fluid to power your brakes. Air is the enemy in a hydraulic system because it reduces pressure and essentially makes the process less effective. When air gets into the brake lines, your brake system suffers
