Disc Brake

With normal brake systems and cable-type disc brake systems, operating

the lever causes a cable to be pulled, which in turn operates the brake

body. In contrast, hydraulic-type brake systems use oil in place of the

cable. As a result, an important point to note with hydraulic-type

systems which is not required for cable-type systems is the prevention

of vapor lock.

Hydraulic

Disc Brake

When the brakes are used, the calipers and rotors become hot. The

heat from the calipers is transferred to the hydraulic oil, which also

becomes hot. This heating of the oil can cause any water or air bubbles

in the oil to expand, which can cause sudden changes in the operating

feel of the brake lever. This phenomenon is called "vapor lock".
