CAUTION:

All tubes and hoses 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.

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 way cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe them with cloth and then wash it away
with water.

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

When removing components, cover brake line connections so that dirt, dust, or other foreign mat-
ters do not get in.

Refill using recommended brake fluid. Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRI-
CANTS" .

Never reuse drained brake fluid.

INSPECTION AFTER DISASSEMBLY
Cylinder Body

Check the inner wall of cylinder for damage, wear, corrosion, and pin holes. Replace cylinder body if nec-
essary.
ASSEMBLY
CAUTION:

Never use mineral oils such as kerosene or gasoline during the cleaning and assembly processes.

Make sure that there is no foreign material such as dirt and dust on the inner wall of cylinder, pis-
ton, and piston cup. Be careful not to damage parts with a service tool when assembling.

Do not drop parts. If a part is dropped, do not use it.
