How to change brake fluid in your car

In fact, all the fluid in the car after a while lose their properties, so they must be replaced from time to time. Brake fluid is not an exception, because its quality depends on vehicle safety. How to change brake fluid in your car, tell in this article. Brake fluids from different manufacturers, without exception, actively absorb moisture from the air. In the case of the moisture is more than 3,5% of brake fluid, the boiling point of liquid drops significantly. This may contribute to failure of the braking system of car during sudden stops. Moisture Absorption occurs most often through the "ventilation" tank, sealing the lapels and glands through the braking system. Certified devices, contributing to correctly determine the state of the brake fluid, are absent in the free enjoyment. That is why auto manufacturers recommend replacing the brake fluid from time to time, about every 2-3 years use, the more so when you change its color, in the case of security. We manufacture replacement brake fluid in your car yourself. Replacement of brake fluid can be produced, both independently and with the help of special equipment. Each method has its advantages and disadvantages. In the case of self-replacement of brake fluid car-owner will spend about two hours, but the need for an assistant. A replacement fluid on the special equipment will cost, of course, more expensive, but will cope with this challenge, and one mechanic for only 15-20 min. Install will replace the fuel fluid under pressure from 1,5 to 2,0 atmospheres, which thus leads to low probability of airing of the brake system is also a system with ABS. Motorists can not afford to replace the brake fluid in cars without ABS and with it, when the accumulator, pump and block gidroklapanov are in the same node. It is advisable to replace the brake fluid in motor vehicles with an integral ABS system with a special scanner. Replacing the brake fluid running alternately in the contours of the braking system (braking device can be learned from the technical description of the car or on the location of highways braking system). To begin working with the most remote from the brake master cylinder, wheel: in the case of a parallel circuit paths - with the right rear wheel, then, everything happens in turn - first the left rear, then right front, and finally, the left front wheel. When a diagonal pattern circuits starts with the right rear wheel, and then proceed to the left front wheel, left rear, and end up right front wheel. It is best to replace the brake fluid to produce a car with the covers wheels on the lookout pit or trestle. If these conditions can not, it is desirable to choose a flat area, and consistently "poddomkrachivaya" car, remove wheel. Vehicle is transferred. Is it convenient to replace the brake fluid, depending on the location of nozzle flow - where, as well as the angle at which they are posted on the brake cylinders. Need to work about 1 liter - 1.5 liters with new brake fluid, translucent tube (diameter 5-6 mm) and capacity (eg, plastic bottle 1,5 l), and end keys on 9 and 11. The need for pumping. During the operation and maintenance of machines, it is possible that in its braking system, able to penetrate the air, and this contributes to a decrease in performance. About it notifies the brake pedal - it becomes a surprisingly "soft", while the floor freezes. Specify which circuit is faulty, it is possible to brake the way the car's wheels. For this purpose, at a speed of about 60 mph the car is stopped abruptly on a flat dry surfaces. Trail tread of the wheel, which later or not at all locked and a sign of airing the brake mechanism. To remove the air brake system must be pumped. In case of replacement fluid stations on the special equipment that gives the brake fluid under pressure, pumping the brakes can not perform. Before you start work, you need to ensure integrity of nodes brake gear, and then fill the reservoir with brake fluid to the maximum. Pumping can be accomplished only with an assistant, who will manage the brake pedal on your instructions. Should be put on fitting the wheel mechanism, which pumps, installation, used to replace the brake fluid - hose, free segment is placed in a container of liquid. Next, you need to brake sharply to click at least 4-5 times, so that the system creates a high pressure, and air bubbles are "detached" from the surface of the channels. In that moment, when the brake pedal is held as an assistant, you need to unscrew the fitting at ? - 3 / 4 turn. Until the brake fluid is displaced into the prepared container, should monitor the presence or absence of air bubbles in it. Once the brake pedal is pressed to the end, wrap socket. These operations must be repeated for as long as the resulting liquid is not wasted air bubbles. In all cases, replace or add brake fluid is not recommended to re-apply the liquid, which was kept open for a long time or merged earlier because in this case there is a high probability of contamination or saturated with water and air. Hammer! After pumping systems, free movement of the brake pedal may increase. Most often, the reason lies in the disorders of the compensation mechanism for clearance pads, a rear brake drum arrangements (usually, it automatically adjusts to the thickness of the pads as they wear). If after repeated taps on the brake pedal and parking brake lever movements, poschelkivaniya in the brakes are not heard, and pedal all the same increase, you need to inspect brakes the wheels, and their repair.
