Brake Fluid: SAE J1703 or FMVSS No. 116 DOT3 NOTICE: If using a dropper to adjust the fluid amount, make sure that the dropper has not been used with mineral oils, water or deteriorated brake fluid. Sealed areas may deteriorate and lead to fluid leaks, or the fluid may deteriorate and lead to decreased efficiency. HINT: The brake fluid level must always be adjusted to the MAX line. |
