BRAKE LINE (HOSES AND PIPES)

•

Inspect all hoses and pipes for wear, bending, chafing,

cracks, dents, or any other damage.

Make necessary correction or parts replacement if these

abnormal conditions are found through inspection.

•

All hoses, pipes and joints can be damaged easily.

Do not allow the hose to become excessively twisted and

bent when working with then, and pay special attention to all

the brake lines not to damage them when repairing or

replacing other parts (axle, suspension, etc).

•

Inspection for leakage should be performed by depressing

the brake pedal fully.

If leakage is apparent at the circumference of joints,

retighten or replace these parts.

This procedure must be performed whenever brake lines

are installed.

•

After disconnecting the hoses and pipes, cap or tape the

openings to prevent entry of foreign material.
