I've never had an issue with ATE, even tracking motorcycles with hydraulic clutches that have slaves very, very close to an exhaust header.

It is what it is.

You will be roasting your clutch long before you cook ATE in the clutch system. I've had the same ATE in my clutch for 5 years of tracking. For brakes ATE is not enough, but the clutch doesn't transfer nearly as much heat to the fluid as the brakes.

What thomsbrain said. I don't think there is any way you're going to boil your clutch fluid. The clutch doesn't get that hot (if it does, it's fried), and the fluid is not in close contact with the clutch disk.

OP, your leak was not caused by pressure/heat in the system. It was probably just its time to give out.

If you need a clutch fluid cooler, you've diagnosed a problem incorrectly. All those parts are cheap, master, slave, line, throwout. It they are 10 years old and you are having an issue, just refresh the system with all new parts.

Thanks for all the tips guys. I've already ordered new OEM master and slave as It's not the first master cylinder I've busted.
The master that just gave out on me had done 50,000km (31,000 miles) so it was probably due.
