Brake fluid: Honda Heavy Duty Brake Fluid DOT 3 Verified

Fluid handling: Use the specified fresh fluid from a sealed container. Keep it clean and off paint; bleeding and hydraulic repairs require the correct service procedure.
Service requirements: Use Honda Heavy Duty Brake Fluid DOT 3. DOT 5 is incompatible. The manual permits sealed-container DOT 3 or DOT 4 only as a temporary substitute and calls for Honda DOT 3 restoration. If the level is at or below MIN, have a dealer check for leaks or worn pads.
