Brake and Clutch Fluid Brake and Clutch Fluid Check the fluid level in the reservoirs monthly. There are up to three reservoirs, depending on which model. They are: Brake fluid reservoir (all models). Clutch fluid reservoir (5-speed manual transmission only). ABS reservoir for cars with ABS option. The brake fluid in the brake and anti-lock brake systems should be replaced every 2 years or 30,000 miles (48,000 km), whichever comes first. MIN 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, it is an indication that your brake system needs attention. Have the brake system inspected for leaks or worn brake pads. Brake System MAX If you add brake fluid to bring it up to the MAX mark, use Genuine Honda Brake Fluid or an equivalent from a sealed container that is marked DOT 3 or DOT 4 only. Brake fluid marked DOT 5 is not compatible with your car's braking system. Maintenance
