Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component which may cause heat
damage or mechanical wear.
Insure nylon tubing in these areas has not melted or
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
Components should be replaced immediately if there is
any evidence of wear or damage that could cause failure.
In order to assure brake system performance, all brake
system components should be inspected periodically.
