Brake Fluid Caution As of BSI

Caution: Use only heavy duty brake fluid conforming to SAE 1704, from a clean, sealed container. This polyglycol brake fluid is hydroscopic and absorbs moisture. Do not use fluid from an open container that may be contaminated with water. Incorrect or contaminated fluid could result in system failure, loss of vehicle control and personal injury.
