Brake and Clutch Fluid
Only use DOT4 brake fluid.
Over time, brake fluid absorbs
moisture, which will reduce braking
effectiveness. The brake fluid
should therefore be replaced at the
specified interval.
Brake fluid should be stored in a
sealed container to avoid water
absorption.
Ensure brake fluid does not become
contaminated.
