Guidelines For Clean Working Conditions

Absolute cleanliness is required when working on the brake system. Do not use any products which contain mineral oil, such as oils, greases etc.
Thoroughly clean all connection points and their surrounding areas before loosening. However, do not use aggressive cleaning agents such as brake cleaner, gasoline, thinners or similar compounds.
Place the removed parts on a clean surface and cover them.
Carefully cover or seal any open components if the repairs cannot be performed immediately (use plugs).
Only use lint-free cloths
Remove the replacement parts from their packaging just prior to installing them.
Only use parts in their original packaging.
If the system is open, do not work with compressed air and do not move the vehicle.
Make sure that brake fluid cannot get into the connectors.
