CAUTION:

All brake hoses and tubes must be free from excessive bending, twisting and pulling.

Make sure there is no interference with other parts when turning steering both clockwise and
counterclockwise.

The brake tubes and hoses is an important safety part. If a brake fluid leak is detected, always dis-
assemble the parts. Replace applicable part with a new one, if necessary.

Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe it off and them wash it away with water
immediately.

Do not bend or twist brake hose sharply, or strongly pull it.

When removing components, cover brake line connections so that no dirt, no dust, or other for-
eign matter gets in.

Refill with new brake fluid “ DOT 3 ”.

Do not reuse drained brake fluid.
