BRAKE TUBE AND HOSE
BRAKE TUBE AND HOSE
Hydraulic CircuitINFOID:0000000001716982
NOTE:
LHD shown RHD similar.
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 coun-
terclockwise.
 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-19, "
Fluids and Lubricants".
 Never reuse drained brake fluid.
