On brushes of screen wipers the road film over time collects, reducing efficiency of their work therefore brushes should be washed out regularly in soft cleaning solution.

Assemblies of screen wipers with brushes should look round regularly. If survey revealed existence of hardenings or cracks on rubber of brushes, replace brushes. If at survey it is not revealed anything unusual, wet a windscreen, include screen wipers, let's to them work a little, and switch off them. A non-uniform trace from brushes on glass or strips on pure glass specify that it is necessary to replace brushes.

If brushes insufficiently well clear a windscreen, the following reasons of it are possible:

   а) When passing by the car of an automatic sink on a windscreen wax particles got. These particles can be removed at addition in liquid of a stekloomyvatel of the detergent possessing property to dissolve wax;
   b) Filling of the tank of liquid for purification of glasses with voskorastvoryayushchy properties can essentially improve action of screen wipers;
   с) Zhirorastvoryayushchiye cleaners unable completely to clear glass.

Damage of brushes can be also the reason of bad purification of glasses, it is necessary to replace brushes.

During operation of the mechanism of screen wipers there can be a weakening of fixing nuts therefore they should be checked and necessarily to tighten each time at check of brushes (address to Heads the Body and Onboard electric equipment for more detailed information on operation of the mechanism of screen wipers).
