Brake Fluid

You've just accelerated through the fastest corner on the circuit and down the straightaway. As you reach the brake marker for the upcoming hairpin, the pedal goes to the floor. Desperately pumping the pedal for some brakes–any brakes–you are lucky to make it around the corner. Ever happen to you? The brakes are gone, the fluid has boiled. What can you do? Change your fluid to the best … AP 551.

Our AP 551 has a dry boiling point that exceeds 550°F. This DOT 3 Motor Vehicle Brake Fluid conforms to SAE J1703, ISO 4925 & F.M.V.S.S. No. 116 Minimum Wet Boiling Point 284°F. AP551 is compatible with magnesium brake and clutch systems. To obtain the best performance from AP Racing 551 Racing Brake Fluid, bleed the brake system thoroughly with fresh fluid immediately prior to each event. This is particularly important in wet or humid conditions or when the brakes are excessively hot. Always use fresh fluid from a sealed container.

AP Racing packages the fluid in 17-ounce (½ liter) plastic bottles. Although AP551 is not silicone based, it should not be mixed with other fluids. Purge your system completely for best results.
