The function of hydraulic brake system is to transmit pressure from the master cylinder to caliper pistons. The system will operate properly if fluid is tight and brake fluid cannot be compressed. Normally, brake fluid cannot be compressed. If however the fluid overheats sufficiently it can partially change to a vapor form. Vapor can be compressed and since the master cylinder has a specific volume with which to build up pressure, the compression of vapor can result in excess brake pedal travel before the system has time to develop adequate braking pressure.
