CAUTION:
Brake fluid may irritate eyes and skin. In case of eye contact rinse thoroughly with water, skin contact wash with soap and water, or if ingested consult a physician immediately.
NOTE:
Avoid spilling brake fluid onto painted surfaces, electrical connections, wiring, or cables. Brake fluid will damage painted surfaces and cause corrosion to electrical components. If any brake fluid comes in contact with painted surfaces, immediately flush the area with water. If any brake fluid comes in contact with electrical connections, wiring, or cables, use a clean shop cloth to wipe away the fluid.
