Caution: Do not use fluid that has a petroleum base. Do not use a container that has been used for petroleum based fluids or is wet with water. Petroleum-based fluids cause swelling and distortion of rubber parts in the hydraulic brake system and water lowers the brake fluid's boiling point. Keep all fluid containers capped to prevent contamination.
Note: The fluid level in the master cylinder reservoir is an indication of the brake system condition. If the fluid level is low, verify that the following conditions are present before filling:
• No brake fluid leaks are present. • The brake linings are not worn out.
