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".
