The Chevrolet Niva braking system, as a joint product of two global companies, is well adapted to Russian roads and has a minimum braking distance when driving in the city. What are the features of this system?

The machine has two independent brake systems - a working hydraulic and parking mechanical system.

The parking brake is applied during a stop to fix the car on the parking place. He uses brake pads just on rear wheels ah and is actuated using a lever located in the cab. When the lever is in the upper position, the brake pads move apart and are pressed tightly against the inner surface. brake drums firmly fixing their position. The pads are moved using a cable and drive levers.

The device of the working hydraulic system

hydraulic brake system Chevrolet Niva, in order to increase the reliability and safety of control, is built according to a double-circuit diagonal scheme. First circuit hydraulic drive drives the front right and rear left wheels, while the second drive drives the front left and rear right wheels. Thus, maintaining controllability in the event of failure of one of the hydraulic drive circuits is achieved. Hydraulic system braking includes:

• brake pedal located in the cab under the right foot of the driver;
• vacuum pedal pressure booster;
• master cylinder with reservoir brake fluid;
• double-circuit hydraulic drive pipeline;
• workers brake cylinders rear and front wheels;
• pressure regulator with actuating lever.

The pressure of the driver's foot on the brake pedal increases vacuum booster and is transmitted to the piston of the master cylinder, which, moving, compresses the brake fluid. The fluid pressure increases and is transmitted through pipelines to the working cylinders of the front wheels and the rear wheel brake pressure regulator. The pistons of the front calipers and rear working cylinders, under the pressure of the brake fluid, extend and press the Chevrolet Nivak brake pads on the surface of the discs and drums, slowing down their rotation.

Purpose and operation of the pressure regulator

The pressure regulator ("sorcerer") is designed to prevent the car from skidding during heavy braking. This is achieved due to the fact that the rear wheels start to slow down after the front ones. The time delay is provided by the regulator lever, which, when the machine is sharply braked (the nose drops and the rear rises), pulls the piston in the regulator cylinder and closes the fluid supply channel to the working cylinders of the rear wheels.

Wherein rear brakes do not work and the wheels spin until the rear of the car drops back down. Thus, the “sorcerer” automatically regulates the fluid pressure in the rear cylinder path in inverse proportion to the load on the rear axle. In addition, it increases the braking efficiency of an empty vehicle when the load on the front axle is higher than on the rear axle.

If the car brakes inefficiently, breaks into a skid or leads to the side, then this is a reason to check and adjust the regulator.

This work needs to be done on every maintenance and after the repair of the rear suspension.

Brake pads Chevrolet Niva

Niva Chevrolet uses disc brakes on the front wheels, and drum brakes on the rear wheels. Accordingly, the pads on them are different. Pads are the main working part of the brakes, which carry a large load and wear out the fastest. With intensive use of the car, the condition of the pads should be checked at least once every six months. Today, there are many different domestic and foreign manufacturers of pads for Niva-Chevrolet cars.

They differ in price, material, service life. The most effective and "cool" are the so-called "Kevlar" pads of the Japanese company NIBK. They are made using modern nanotechnology from a compound that is equally effective in various operating modes. The advantages of this pad model include:

• low heating temperature during braking;
• do not require heating in winter;
• do not creak or squeal even during sudden braking;
• have a long service life compared to other models.

The disadvantages of these pads can only be attributed to the high cost, but the price corresponds to the quality.

Skoda Octavia Scout - from 1,962,000 rubles

Automotive journalists have long understood the European auto culture, which for some reason with such difficulty goes to the masses in the two largest countries of the Eurasian continent - Russia and China. But if the car culture of the Celestial Empire is a topic for a separate analysis, then with Russia everything is quite simple. "Image is nothing" - it's still not about us! A car in Russia is a kind of calling card. And this is one of the reasons why, other things being equal, most motorists make a choice not in the direction of the functionality of family station wagons, but in favor of the status of sedans and large SUVs. The second reason is banal: roads, which sometimes provoke people to choose family car albeit urban, but still a crossover. All-terrain all-wheel drive station wagons could reverse the latest trend. But there are very few of them on the market, not only here, but also in the world, and most of them - Audi A6 Allroad, Volvo V90 Cross Country and Subaru Outback- refer to premium segment or next to it, and therefore very expensive. Perhaps the only more or less budget (although also not so cheap) alternative for those who need to combine functionality family station wagon with comfort passenger car and crossover patency, - new Skoda Octavia Scout.

V Russia Skoda The Octavia Scout comes with only one four-cylinder 180-horsepower TSI turbo engine with direct injection. In combination with a 6-speed DSG “robot”, this engine is enough to provide the Scout with more than a frisky acceleration to hundreds in 7.8 seconds. But the declared consumption of 6.8 l / 100 km is practically unattainable in practice. Real Appetite Scout Mode long-term operation exceeded 12 liters per hundred. 280 Nm of torque for an all-wheel drive all-terrain vehicle is also, of course, not outstanding, however diesel engines in our country, Skoda offers so far only for Kodiaq.

Despite the general model line, the station wagon differs very seriously from the latest generation Octavia liftbacks. The proportions of the body look, perhaps, not as elegant as that of the liftback, but they add decent space in the cabin. In this car, everything is subject to functionality! Compared to the previous version of the all-wheel drive station wagon, new Octavia Scout received a more expressive "muzzle" with a wide grille and optional LED adaptive headlights and a wider rear also with LED lights. The Rough Road Package is included in standard equipment and includes composite underbody protection, fuel and brake lines.

The layout and volume indicators of the cabin remained the same. Volume luggage compartment varies in the range from 588 to 1718 liters.

The landing of the driver and passengers in the Scout is higher than in the road versions of the Octavia. This does not negatively affect comfort, but improves visibility. Like the road versions, Scout received a new multimedia system with a trapezoidal 9.2-inch touch screen in the center console. However, in relation to an all-terrain vehicle, the Czechs' passion for touch-screen technologies does not look as clear as on the road versions. On off-road, it is much more convenient to operate with traditional buttons and controls, as implemented in Skoda Kodiaq rather than poking your finger at the screen. In terms of trim, the most significant innovation was the upholstery of the seats with a new breathable fabric created using Thermo-Flux technology, which is twice as breathable and moisture permeable as conventional fabric. fabric upholstery. As in all model line, Scout has also added a new atmospheric LED backlight.

From basic road station wagon Octavia Combi new Scout is distinguished primarily by plastic side sills and extensions wheel arches, silver-colored body protection front and rear, as well as silver-colored mirrors. Departure angle increased to 14.5 degrees. The ground clearance (17 mm more than the Combi) has not changed compared to the pre-styling version: all the same 171 mm. However, the overall geometry of the car has been somewhat redesigned: thanks to the new multi-link suspension rear track width increased immediately by 33 mm. The basis of the system all-wheel drive Scout serve hydraulic multi-plate clutch with electronic control front rear axle and electronic differential lock XDS+ on the front and rear axles with diagonal torque distribution function for increased cornering stability. In addition, in Octavia equipment Scout now includes top auxiliaries electronic systems front distance control with function emergency braking, Blind Spot Assist, Parking Exit Assist in reverse and Trailer Assist.

Traditional for everything model range Skoda smart solutions» Simply Clever makes driving even more comfortable. Latest-generation goodies include a one-handed bottle holder, a removable LED flashlight in the trunk, two USB ports for passengers back row, keys with the ability to personalize the settings of various car systems, and, of course, a banal electrical outlet, still in addition to Skoda affordable for some reason, only in a few cars of premium segments.

Driving A segment-unique combination of comfort, handling, dynamics and off-road capability. Salon Spacious and extremely comfortable. In addition to the exclusively touch control of the central screen, there is nothing to complain about. Comfort The comfort of a passenger car is combined with the maneuverability of a light crossover. With the advent of adaptive crisis control, it has become absolutely comfortable even on long trips.
