Brake fluid

The fluid level will drop slowly as the brakes wear, and will rise when the brake components are replaced.
Fluid levels between the MIN and MAX lines are within the normal operating range; there is no need to add fluid. If the fluid levels are outside of the normal operating range, the performance of the system could be compromised; seek service from your authorized dealer immediately.
