Notes On Evaluating Leakages - AH00.00-N-0011-01A

Model all 

The instructions described below do not apply to hydraulic brake systems. No sweating is permitted at hydraulic brake systems.

Even extremely minor leaks at hydraulic brake systems can impair the braking effect and, as a result, cause injury, damage and environmental pollution.

Before starting repair work due to leakage from a major assembly, the type of leakage present must be carefully checked.

• Moist areas from which no liquid is dripping or running are not a cause for complaint. This refers here to "sweating".

  Even with today's levels of technology, this "sweating" cannot be prevented in all cases and has no negative effect on system function.

  Any repair work performed will only result in an improved appearance.

  As such, it cannot be justified.

  For more accurate inspection, clean the affected areas and monitor them over a suitable period of time.

• If the complaint concerns fluid that is visibly dripping or running, then appropriate repairs must be performed to stop this type of leakage.
