RH DOT-4 Brake Fluid is recommended for all hydraulic brake and clutch systems for which a non-petroleum fluid is specified. Exceeds specifications SAE J1703 and ISO 4925. Minimum Dry Boiling Point 260 °C. It’s recommended that DOT 4 Brake Fluid is changed every 2 years for to maintain maximum braking performance and safety.
Water contamination can shorten the life time of the braking system. Brake fluid absorbs moisture via the brake hoses. As brakes are used, the brake fluid will heat up. Over time, the boiling point of all brake fluids will begin to lower as moisture from the air is absorbed. If brake fluid is not changed regularly, master cylinders and wheel cylinders rubber parts will corrode.
