HYDRAULIC BRAKE LINE REPLACEMENT (Contd)

WARNING

Short front flexible hydraulic brake lines are subject to

failure during full steering travel and must be replaced with

new, longer flexible hydraulic brake lines P/N 7409330.

Failure to comply may cause injury or death to personnel.

Accidental or intentional introduction of liquid contaminants

into the environment is a violation of state, federal, and

information concerning storage, use, and disposal of these

liquids. Failure to do so may result in damage to environment

and health of personnel.

CAUTION

Cap or plug all openings immediately after disconnecting lines

and hoses to prevent contamination. Failure to do so may result

in internal parts damage.

replaced the same. This procedure covers the front flexible

hydraulic brake line.
