  • Can be also used with conventional steel discs and clutch systems actuators

Dry Boiling Point vs Wet Boiling Point Explained:

  • The dry boiling point refers to the boiling temperature of fresh, brand new brake fluid. Whereas the wet boiling point refers to the temperature DOT brake fluid begins to boil after it has absorbed 3.7% water by volume. DOT brake fluid will reach this level of water volume after roughly 2 years of use, which is why it is advisable to renew the brake fluid every 1-2 years. (it is not uncommon for track cars to replace the brake fluid every 3-6 months, or racers to replace the brake fluid every single event)

note: do not mix brake fluids, perform a flush with the brake fluid you intend to use.
