Replacement of a brake liquid

Replacement of a brake liquid does necessary not only already mentioned danger of formation of air vials, but also danger of occurrence of corrosion in brake cylinders and pipelines for the reason впитывания a moisture. At replacement of a brake liquid it is necessary to operate in the same way, as well as at prorolling. 2 l of a new brake liquid be required to you.


    Whenever possible to devastate a receiver with a brake liquid by means of an old medical syringe and at once again to fill it. To pump over a brake liquid until from the prorolling valve there will be no fresh liquid. For this purpose to pump over through each valve of a brake liquid of 500 sm3. In this case each drop will appear гарантированно replaced. Sequence of replacement: behind on the right, behind at the left, in front on the right, in front at the left.

 The help: the used brake liquid in no event cannot neither be poured out in the water drain, nor to add to the fulfilled oil. The best – to hand over it in separate capacity on recycling of a special waste (you can learn a site of the nearest similar institution in a local justice).
