Ford Fokus>> Introduction>> Periodic service and care of the car>> The control of level of a brake liquid
On the panel of devices of the car there is an alarm lamp of malfunction of brake system. If the car is not braked by a lay brake the lamp dies away. If is not present, check up level of a brake liquid in the broad tank which is at level of a forward wall of a body under a cowl. If the lamp periodically lights up during a trip the possible reason is insufficient level of a brake liquid in a broad tank or one of brake contours is faulty. The second brake contour remains efficient, and you can cautiously reach to the nearest workshop.

The broad tank (a Fig. 34) a brake liquid is located near to a forward wall of a body under a cowl. Regularly check level of a brake liquid. Even at efficient brake system liquid level can decrease. The reason — deterioration of brake overlays, pistons receive the increased course, as a result additional volume of cylinders is filled with a brake liquid. Level of a brake liquid in a broad tank should is between marks min and max. The basic components of a brake liquid are polyglycol and полиоксиэтилен. The mix of these components remains fluid still at–40 With and has high enough boiling point — approximately 270 S.Tormoznaja a liquid гигроскопична — it constantly absorbs a moisture which is in air through a cover of a tank. Approximately to 2 % every year. At moisture content to 2,5 % the boiling point falls to 150 With. In such situation at strong нагретых brakes (a trip to the mountains, full braking, driving with the trailer) in a brake liquid is formed a steam stopper. The steam stopper operates approximately the same as air in brake system — a brake pedal "fails" to a floor. Replace a brake liquid — in interests of your safety — two times in a year.
Recycling of the used brake liquid
The brake liquid is poisonous. Avoid its contact to an oral cavity or open wounds. It aggressively influences paint and varnish coverings. The used brake liquid should be necessarily utilised. Do not apply a brake liquid from the tank which has staid long time without a cover.
