You do realise ‘that is one brake system’, hope brakes used to be and maybe still are awful for brake draggers hence the snooker ball pistons to help, they do boil fluid compared to other systems.
Shimano and avid sorted boiling brakes years ago with two very different braking fluid. Magura to have it sorted from word go.
If you look closely at any Shimano piston from the last 8 years or so, it’s got a phenolic insert which holds the pad away from the metal piston.. The only brake I ever managed to boil was an old Deore which was pre this design.
C2 pistons used to have fins on the inside to dump heat from the pads and piston into the fluid!
I read that article before.. The guy has some good points to make. It’s not as if he was using anything too unusual or doing anything that out of the ordinary. He won’t be the last person so build something up that’s got no mass in the rotors to dump heat into, and then drag his brakes so that they overheat. There’ll be a lawsuit or two thrown about and then some new warning labels on new bikes before it becomes common knowledge amongst roadies about how to brake properly.
