Replacement of brake fluid

Replacement of brake fluid is done necessary by not only already mentioned danger of formation of air bubbles, but also danger of emergence of corrosion in brake cylinders and pipelines because of moisture absorption. When replacing brake fluid it is necessary to work in the same way, as well as when pumping. You will need 2 l of new brake fluid.

 PERFORMANCE ORDER

  1. Whenever possible to devastate a receiver with brake fluid by means of the old medical syringe and at once again to fill it.
  2. To pump over brake fluid until from the valve of pumping fresh liquid does not appear.
  3. To pump over for this purpose via each valve 500 of cm3 of brake fluid. In this case each drop will be guaranteed replaced.
  4. Sequence of replacement: behind on the right, behind at the left, in front on the right, in front at the left.

 Hint: it is impossible neither to pour out the used brake fluid in the sewerage at all, nor to add to the fulfilled oil. The best – to hand over it in separate capacity on utilization of special waste (you can learn location of the next similar institution in a local justice).
