Brake Fluid Independent of the Maintenance Midner information, replace the brake fluid every 3 years. Check the fluid level in the brake fluid reservoir monthly. Always use Honda Heavy Duty Brake Fluid DOT 3. If it is not available, you should use only DOT 3 or DOT 4 fluid, from a sealed container, as a temporary replacement. Using any non-Honda brake fluid can cause corrosion and decrease the life of the system. Have the brake system flushed and refilled with Honda Heavy Duty Brake Fluid DOT 3 as soon as possible. Brake fluid marked DOT 5 is not compatible with your vehicle's braking system and can cause extensive damage. MIN MAX The fluid level should be between the MIN and MAX marks on the side of the reservoir. If the level is at or below the MIN mark, your brake system needs attention. Have the brake system inspected for leaks or worn brake pads. Maintenance 525
