AP Racing Radi-CAL R2 Racing Brake Fluid

AP Racing Radi-CAL R2 is the entry point to AP's racing-fluid range — a fully synthetic DOT 4 with a 312°C dry boiling point for club racing, HPDE, and hard street use. It delivers a firm, consistent pedal at the temperatures a street-based track car generates.

Like all racing fluids its 195°C wet boiling point falls as it absorbs moisture, so bleed regularly and flush each season. DOT 4 compatible and mixes with conventional DOT 3/4 fluid for bleeding.
