Make sure there is no interference with other parts when turning steering both clockwise and counterclockwise.
The brake piping is an important safety part. If a brake fluid leak is detected, always disassemble 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 areas, wash it away with water immediately.
Do not bend or twist brake hose sharply, or strongly pull it.
When removing components, cover connections so that no dirt, dust, or other foreign matter gets in.
