Formerly branded as AP Super 600
AP Radi-CAL R2 is a high-performance brake fluid formulated specifically for racing. The very high boiling point resists brake fade in challenging braking applications such as short road courses. To keep the fluid fresh, AP brake fluids are furnished in 1/2 liter (16.9 oz), easy pour plastic bottles with double sealed caps. Bottles should always be tightly resealed to keep moisture out.
Warning: AP Radi-CAL R2 should never be mixed with any other type of brake fluid. Because Radi-Cal R2 is corrosive to magnesium, it is not recommended for clutch applications. Radi-Cal R2 releases a gas when it comes in contact with magnesium components, which can cause failure of the clutch hydraulics.
