Domestic cars are reliable andquite durable, despite the fact that they are scolded everywhere. Low cost, the availability of the element base - these are the key points when choosing a car. But each driver tries to improve his iron horse, so for the beauty and reliability often put rear disc brakes on the VAZ-2114. Yes, it is beautiful - drum look poor on cast wheels. And reliably - the effectiveness of the brakes is increased several times in comparison with the standard equipment of the car.
Basic information
Since the release of the first car onAutomobile plant in Tolyatti, and this was the model "Lada-2101", popularly known as "penny", almost to this day the scheme of the braking system of all cars remained unchanged. Ahead of the disc were put, and behind the drum. This is logical, since the main load during braking falls on the front.
Of course, such a scheme is much more efficient thanthe GAZ-24, in which there are drums in a circle. Because it will not be a secret that the disc brake pads seize much better, and the way to a stop, respectively, is much less.
Tuning VAZ-2114
ВАЗ-2114 – это довольно свежая модель, которая replaced the famous nine. The base of the car is the same, even such little things as the taillights, and they are similar. But you can only significantly improve the car yourself.
It is worth noting that "Lada-Kalina" is the firstthe model on which the disc brakes on the rear axle are installed from the factory. And you still need to mention that you make all the changes in your car at your own peril and risk. Intervention, modification of the design, steering, brake system, is punishable by the removal of state numbers and the prohibition of the operation of the vehicle. But if it doesn't scare you, you can continue reading.
What you need for tuning
If you still decide to put the rear disc brakes on the VAZ-2114, you need to know what elements are required for this:
- Brake discs.Ideal are those that are installed on the front wheels of the VAZ-2114 or similar models - 2108, 2109. Their diameter should be 240 mm. But you need to pay attention to the fact that you cannot do without a turner - the hub differs slightly in design. And more specifically, it will have to be bored from a diameter of 58 mm to 60.
- Calipers, brake pads, hoses - also from the front brakes of the Samara-1 and Samara-2 generation models. Therefore, you can safely buy the whole set of front brakes on the nine.
- Plates for holding fasteners calipers. You can either make them yourself or purchase them in car shops.
- 12 bolts М10Х1,25, length 30 mm.
- Remote washers - 8 pieces. Ideal are those that are installed in the gas distribution mechanism of the 8-valve models VAZ-2109 and 2114.
Well, that's all bought all the parts in stockthere is all the necessary tools. It remains the case for small - to carry out a complete modernization. It should be noted that the fairly new VAZ-2114 (their price in the secondary market remains high) do not have rear brakes, but are reworked without much difficulty.
Dismantling the assembly
Before disassembling the entire brake system on the backaxes need to drain fluid. To do this, unscrew the pumping fittings located on the calipers. Consequently, in the future will have to do pumping. The initial work is as follows:
- Loosen the cable and reduce the pads.Unscrew the guide pins that secure the drum to the wheel hub. If it is not possible to remove the drum easily, treat the seat abundantly with penetrating WD-40 grease. It should always be on hand when carrying out such repairs. Even more - in advance (in about half an hour) it is necessary to treat all threaded connections with this fluid.
- Remove the springs with a flat screwdriver and remove the spacer bar. Disconnecting the parking brake cable, you can completely dismantle the old, now unnecessary pads.
Please note that the parking brake now you havewill not (if not install hydraulic). Therefore, absolutely all components that somehow relate to the cable, including it, can be removed. And now you need to talk about the installation.
Installation of disc brakes
Расположение суппорта механизма может быть как in front and behind the rear wheel axle. It will work anyway, but if you install it from behind, the efficiency becomes a little higher. Further, your task is to correctly make the hub and faceplate docking. Pay attention to defects, even the smallest. In the event that there are drawbacks, re-do the joining work.
Spend a rikhtovka of corners of a back beam.Without this, it will not be possible to put the rear hub. The most convenient way to straighten using grinders. To install the disc brake caliper, you need to take a few more steps:
- Mount brackets on the faceplate.
- Fix the brake disc on the wheel hub.
- Install distance washers in contact points to increase reliability.
- Fix the faceplates and staples.
- Seal the brake mechanism.
- Fix the caliper and install the brake pads.
Вот и все, в целом, как можно видеть, работа uncomplicated. But care should be taken when installing, use only new elements, especially bolts. Do not use bolts that were in use. The thread they have already deformed, although it is not visible to the naked eye.
Positive qualities of disc rear brakes
Да, главный плюс – это увеличение безопасности.The stopping distance is reduced, and it does not depend on the weather. The work node is stable, the weather in no way affects it. For example, during a rain drum brakes become ineffective, the stopping distance increases. This is not observed when using discs.
Overheating is not terrible disk designs.For example, when braking at high speeds, the fluid in the system is heated due to the high friction force. The drum and the pads can warm up almost red hot - up to 600 degrees. As a result, the pedal fails, braking performance deteriorates significantly. This you will never feel if disc brakes are installed. Their device is simple and high reliability, so you should not worry about safety.
Pumping brakes
After all the work has to be donepumping - getting rid of air in the system. This is essential for improving work efficiency. And since the modernization has begun, do not forget to change all the components that have been serving for a long time. Replace hoses, front pads, VAZ-2114 brake vacuum booster, master cylinder. As for the liquid, then it should be changed about once every two years. In short, the procedure for pumping looks like this:
- Pour the liquid into the expansion tank.
- Pump over the right rear caliper.
- Check the level of fluid, if necessary, topped up.
- Pump over the left rear caliper.
- Repeat p.3.
- Pump over the right front caliper.
- Perform p.3.
- Pump the front left caliper last.
Here's how to pump the brakes VAZ 2114 correctly, the essence of the procedure is to go from the far to the nearest caliper (relative to the main brake cylinder).
Need a handbrake?
Но некоторые автомобилисты не могут обходиться without parking brake. A new VAZ-2114, the price of which at one time was close to 300 thousand, without the parking brake, and this is not very convenient. In the cities in the parking lots without it just nowhere. And if the autorun system is installed, then you simply cannot do without the parking brake - it is not recommended to set speed.
What is needed to install this mechanism?First of all - it is the handbrake itself, but not wire-wire, but with a hydraulic cylinder. As a rule, they are universal, and Chinese new mechanisms cost from 1,500 rubles and above. And rear disc brakes on the VAZ 2114 will be equipped with a parking brake system.
The installation procedure is extremely simple - put it onplace the old one, fasten with bolts, connect to the hydraulic system, namely, to the part that controls the calipers on the rear axle. That's all, from now on you will be with the handbrake, which will work perfectly in any conditions. Neither overheating, nor frost, nor pouring rain is terrible. And even in the cold you can use the handbrake.
Conclusion
When will the installation be completed and carried outbleeding, adjusting the brakes, carefully inspect all components, tighten the threaded connections. And after the first exit on the road, you will feel the difference with the previous braking. It will be much more efficient, the car will become more stable.
It must be admitted that such refinement is necessary, andTraffic police must resolve it, albeit with reservations. The collective farm can not, at least the acceptance of work and permission to operate must give an experienced master. Of course, this is a dream, this will not happen. Therefore, it is necessary so far to carry out modifications exclusively at your own peril and risk.
But the fact is that the rear disc brakes on the VAZ-2114 are efficient and reliable. And you will benefit from their installation, having protected yourself, your passengers and pedestrians.
