Why are air bubbles dangerous in hydraulic brake systems ?

Expert Answer:

In hydraulics, we depend on the ability of the hydraulic fluid to transfer energy from the input end of the system to an output end.
The energy associated with compression of the fluid at the input end is "used up" compressing a bubble in the line, therefore that much energy that won 't be to the output end.
Compression of the fluid at the input end results in compression of the bubble rather than the delivery of energy to the output end.
But in a brake system, this is a disaster because it leads to poorly performing brakes, or even a failure, so on a moving vehicle, the failure of the brakes frequently spells disaster.
