AP Radi-CAL R4 is a high-performance brake fluid formulated specifically for professional racing. The extremely high boiling point is suitable for the most demanding braking applications such as carbon/carbon brakes or NASCAR short tracks. Exceeds DOT 4 specifications but is compatible with all DOT 3 and DOT 4 fluids.

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.

AP Radi-CAL R4 Specifications:
DOT Rating - 4
Dry Boiling Point - 644° F
Wet Boiling Point - 399° F
Compatible with other fluids - DOT 3 & DOT 4*
Container - 16.9 fluid ounce (500ml) plastic bottle

* None of our brake fluids are compatible with silicone-based (DOT 5) fluids.

For maximum performance, the system should be drained and thoroughly purged with fresh R4 fluid. Any old fluid remaining in the system will act as a weak link, lowering the effective boiling point to match the old fluid.
