If your car has small discs and calipers, small pads and/or lack of brake cooling then your brakes may run extremely hot, with heat transferring into the brake fluid. The AP Racing R4 Brake fluid works at extremely high temperatures, giving the brake fluid great resistance to heat from heavy braking on track. Its significantly better than the AP Racing R3 Brake Fluid.

  • Highest Dry Boiling Point Of Any Brake Fluid
  • Resistant To Vapour Lock

The AP Racing Radical R4 brake fluid is the creme de la creme of race brake fluids. This AP Racing R4 fluid can cope in motorsport conditions where abnormally high temperatures are experienced and other fluids just don't hold up. At 340°C (644°F) the dry boiling point for the AP Racing R4 fluid is the highest of any racing brake fluid currently available. Under extreme race conditions this will give an improvement versus other fluids such as the Castrol SRF which has a dry boiling point of 320°C or the Motul RBF660 which has a dry boiling point of 325°C.

If your brake system is needing a fluid with a dry boiling point this high - we recommend looking at the Motul RBF700 brake fluid which has a dry boiling point of (336C) but is considerably cheaper

R4 can be mixed with DOT3 and DOT4 racing brake fluids but for maximum product performance the brake system should be thoroughly purged with R4 fluid.

With outstanding resistance to vapour lock / pedal fade under the most exacting conditions. A higher vapour lock point means a firmer brake pedal at the extremes of brake temperature. Enhanced lubricity, means this fluid is an even better lubricant than the AP Racing Radical R3 (PRF660) brake fluid itself a market leader. This helps the life of the metal moving parts of the brake system and increases system efficiency.
