Visual Inspection

CAUTION: Because vacuum hose contains a check valve, it must be installed in the correct orientation. Refer to the stamp or label to confirm correct

installation. The brake booster will not operate normally if the hose is installed in the wrong direction.
Do not use lubricating oil during assembly.

VISUAL INSPECTION 
Check vacuum hose and connections for air tightness, improper attachment, chafing and deterioration. Repair or replace as necessary.
