Sell your old car and immediately buy another car model. This tempting idea is perfectly implemented by the “Trade in” program or the “key-to-key” car exchange service. Popular in Western countries, procedures for simultaneous redemption of an old car for the cost of a new car are still new on the Russian market. What are their advantages? Let's talk about this further.
“Trade in” or changing the car “key to key”
The “Trade in” service involves the sale of a used car, the proceeds from which go towards paying for a new model. In this way, the owner only has to pay a fixed amount in order to transfer to a new vehicle.
Key-to-key car exchange differs from the previous service in that the owner exchanges his car for a suitable used model, subject to an appropriate surcharge.
These two relatively new ways of buying cars eliminate the risk of fraud that is common when a car is sold second-hand on the market. Transactions are formalized by leading auto companies in accordance with the current legislation of the Russian Federation.
How to bleed the brakes on a VAZ 2107
The VAZ 2107, like all cars, has a hydraulic brake system (with brake fluid), which requires regular maintenance. This diagnostics must be carried out regularly, which will eliminate various malfunctions that can cause accidents on the road. In addition to replacing and repairing related parts, the brake system sometimes needs to be bled to get rid of air bubbles. We'll look at how to bleed the brakes on a VAZ 2107 in the article.

When to bleed the brakes
The brake system on a VAZ 2107 car begins with the pedal and ends with brake pads with discs at the front and drums at the rear. The principle of operation of brakes is based on increasing the pressure of the fluid filling the entire system. The fluid pressure increases due to the displacement of the piston in the design of the master cylinder (by pressing the pedal). Next, the pistons move in the calipers (working cylinders) and they put pressure on the front and rear pads and stop the car. For the brakes to work effectively, all parts must be in good working order and there must be no air in the system.
Bleeding the brake system on the seven is carried out under the appropriate conditions:
- When is the fluid replaced? Usually it is recommended to change it every 40-50 thousand kilometers.
- When carrying out repairs, the brake cylinders and hoses, the expansion tank are changed, and the master and working cylinders are also repaired. When replacing pads, bleeding the brakes is not necessary.
- If signs of fluid leakage are detected.
- If brake performance deteriorates. In this case, you must first make sure what may be causing the deterioration in braking quality. Air penetration into the system is one of the main signs of reduced braking quality.
If air gets into the system, its efficiency decreases.
What you need for pumping
Before you begin the procedure, you will need to take the appropriate tools. It must be said right away that the pumping procedure is not difficult, but it will require two people. One is located inside the car and presses the brake pedal. The second is located in the inspection hole, for the rear wheels or on the side, when pumping the front wheels, which are previously dismantled.
To bleed the brake system on a VAZ 2107, you should stock up on the following tools:
- Wrench for brake pipes (special) 8 mm and 10 mm.
- Open-end wrench for 8 mm and 10 mm.
- The hose is transparent with the appropriate diameter and length for fitting onto the caliper bleed valve rod.
- A container for draining liquid from the system when pumping it.
- Brake fluid.
If the design of the caliper contains fittings with a key of “8”, then it is necessary to replace them with the same ones, but only with a key of “10”. These fittings are much stronger and stronger, so it is better to replace them immediately.
How to bleed the brakes on a VAZ 2107
Many people consider the process of repairing brakes to be a complex and responsible undertaking, so they do not risk carrying out its repair. The maximum that most car owners are willing to do is replace the pads. However, both the repair and the process of bleeding the brake system on the seven does not present any difficulties. You need to do everything according to the instructions once, so that next time you can do everything automatically.
The sequence of actions for bleeding the brake system on a VAZ 2107 is as follows:
- The line has a corresponding procedure for bleeding the brakes of the VAZ 2107. You need to start from the most distant point, that is, from the rear wheel on the passenger side. It is important to follow the pumping sequence, otherwise the actions taken will be ineffective.
- You need to bleed the right rear wheel first, and then the left rear. After this, the right front wheel is pumped, and then the left wheel, which is closest to the master cylinder. Knowing the order of pumping, we will find out how the procedure is performed correctly.
- We go down into the inspection hole, from which the rear brakes can be conveniently pumped. To bleed the front ones, it is better to remove the wheels, as this is much more convenient.
How to profitably exchange a used car
To guarantee the legality of the used car exchange service and its objective cost, the purchase and sale process should be carried out at a trusted auto center. Here the client will be offered:
- Diagnostics of the old model, on the basis of which its cost will be determined;
- Selection of cars for exchange, completely new or with a clean mileage history: all cars undergo forensic examination, therefore the car dealership will never sell a car with a “dark past”;
- Legal support of the transaction: the client enters into a notarized agreement and, if necessary, can use the credit services of the car dealership’s partner bank;
- Efficiency of the service: the client does not need to look for buyers for his vehicle; he does not need to settle issues with the traffic police or the bank. The listed functions are the task of the auto center.

Thus, with minimal documents, it is possible to buy an improved car within one to three days. The used car exchange service makes it possible to regularly change the owner’s vehicle fleet by purchasing its best models.
How to bleed the brakes on a VAZ 2107
For ease of work and to ensure free access to the brake cylinder fittings, you should use an inspection hole. The design of the front brake mechanisms requires removal of the wheels to bleed the brake system.
Before starting work, it is necessary to fill the brake reservoir to the maximum, and during bleeding, you must ensure that it is constantly filled with brake fluid. If you miss this moment, air will get into the working cylinder and you will have to start work again.
Bleeding the brakes with an assistant
Bleeding the brakes of a VAZ 2107 requires that an assistant sits behind the wheel and, at the command of the mechanic who performed the replacement, responds to shouts of “pump!” actively pumping up pressure in the system to expel air from it. "Hold it!" - meant that the mechanic unscrewed the fitting and the air, along with the old fluid, came out through the tube. The pedal had to be at the very bottom before the “Start!” command was received. In this case, among the special devices for pumping it was necessary to have:
- container for pumping and draining old fluid;
- a nylon tube with such a diameter that it fits flush onto the fitting;
- a spanner for bleeding, so that it is convenient to unscrew the fitting;
- a tube tip (optional), which worked as a check valve and was taken from the washer reservoir.
Later, even on sale, in the heyday of cooperative trade, special caps for the brake fluid reservoir, in which a nipple from a tubeless tire was embedded. Hit of the late 80s. We'll tell you how to use it right now.
↑ Special cases
If, even after prolonged removal, air continues to come out of the hose in the form of bubbles, it means that it enters the system through damage in the pipelines due to insufficient tightness of the connection or due to a malfunction of the master or wheel cylinders.
If air removal is performed on a car whose brake system has been in use for a long time, then replace the fluid in the system with new one.
The liquid suitable for further use must be carefully filtered and then allowed to settle in a hermetically sealed container.
Design of the VAZ 2107 brake system
The design of the VAZ 2107 brakes takes us back to the times when the city of Tolyatti was a wasteland, the whole country drove Muscovites and Volgas with drum brakes, and only read about disc brakes in the “Their Morals” section of the Za Rulem magazine. Capitalists have been riding on luxurious cooled and ventilated disc brakes since the 30s, but this design innovation reached us only in the second half of the 60s, and then at the instigation of Fiat. Moreover, the seven was equipped with a pneumatic brake booster, which generally made the car almost a Lincoln compared to the car nightmare that was sold to private owners at that time.
Tuning methods
Which method of tuning the dashboard to choose will depend on the skills and financial capabilities of the car owner.
- You can buy ready-made parts for tuning and install them instead of the original ones. This is not the cheapest or most original method, but it is simple and will immediately change the appearance of the panel and the entire interior. There will be no problems with installation; the connectors are designed in such a way that it is impossible to make a mistake when connecting devices.
- Purchase additional instruments (econometer, on-board computer, thermometer and much more) and harmoniously fit them into the classic design of the car’s instrument panel.
- Make tuning yourself by replacing the arrows and scale, installing backlighting on the instruments. You can buy arrows and instrument scales or make them yourself.
You should start by removing the panel, regardless of whether you do the dashboard tuning yourself or install ready-made devices.
Brake bleeding devices
The plant officially recognized only one method of bleeding the brakes - the one described in the user manual. But inventive car enthusiasts found more and more new options for how to bleed the brakes on a VAZ 2107. In principle, two people needed to bleed the brakes. According to the old habit, when the line systems were unreliable, the brake cylinders were bulky and bulky. In the seven, it was possible to completely replace the brake fluid in 15 minutes, without any difficulties, even alone.
