BRAKE TUBE AND HOSE
Revision: 2007 April2007 M35/M45
CAUTION:
All brake hoses and tubes must be free from excessive bending, twisting and pulling.
Make sure that there is no interference with other parts when turning steering both clockwise and
counterclockwise.
Brake tubes and hoses are an important safety part. Always disassemble the parts and retighten
their fittings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged
part is detected.
Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
Cover the open end of brake tubes and hoses when disconnecting to prevent entrance of dirt.
Refill with new brake fluid “DOT 3”.
