Vehicles, like the Boxster, with ABS and stability management systems are more prone to issues due the system pump, the number of valves in the control network, etc. in the PSM/PASM technology. You want to see big repair bills, screw up the hydraulic control network in the PSM. Conveniently, the replacement or removal for cleaning of any of the hydraulic pump or control valve system requires cycling the system electronically with the PIWIS computer system just to get the air out of it; hardly a “backyard” project. This is why the standard maintenance schedule for the 986/987/Cayman and other models included brake/clutch system flushes at least every two years. Astute shops actually pull fluid samples and test them rather than depending on a fixed schedule; and some cars actually need to have the fluid done more frequently due to environmental or usage related issues................

Considering how low-cost a system flush is, it also qualifies as cheap insurance……
