The most common point of failure for the early hydraulic TOBs was their banjo fittings which used o-rings to provide a seal. They looked cool but the clutch heat in the bellhousing would deteriorate the banjo fitting o-rings over time and the TOB would begin to leak.

When McLeod went to their second generation hydraulic TOB they eliminated the banjo fittings and used plain fittings with NPT threading to go straight into the TOB. Once the banjo fittings and their o-ring style seals were gone so to were the leaks.

The external slave cylinder with a mechanical throwout bearing arm is by far the most straight forward clutch release mechanism. More importantly if the hydraulic paraphernalia does go kaput, for whatever reason, it is easily serviced on the outside of the bell housing.
