BRAKES 5-11
Figure 10 Center Brake Pipes (Typical)
brake hoses should be checked for road hazard damage,
for cracks and chafing of the outer cover and for leaks and
blisters.
A light and mirror may be needed for an adequate
inspection.
If any of the above conditions are observed on a
brake hose it will be necessary to replace it.
Do not allow brake components to hang from the flexible
hoses as damage to the hoses may occur. Some brake
hoses have protective rings or covers to prevent direct con-
tact of the hose with other chassis parts. Besides causing
possible structural damage to the hose, excessive tension
could cause the hose rings to move out of their proper
locations.
