How to change the handbrake cable on a Chevrolet Niva

How to replace the handbrake cable

Sometimes adjusting the handbrake does not bring the desired result due to the fact that the rear cable is overstretched. In this case, the only way out of the situation is to replace the Chevrolet Niva hand brake cable. In addition, the cable will have to be replaced if it regularly jams in the protective sheath or breaks due to wear.

To carry out the replacement, the rear of the vehicle must be in a hanging position. Therefore, lift it using a lift or jack and remove the brake drums from the rear wheels.
Using a “12” wrench, loosen the locknut on the adjusting rod and completely unscrew it together with the adjusting nut. You must first remove the spring from the rod, as it will not allow you to unscrew the nuts.
After this, you can easily remove the cable equalizer and remove the cable itself from it.
Next, by pulling the cable towards you, remove the ends of the shell from the brackets located on the left and right on the bottom of the body.
Using manual force, remove the right and left branches of the cable from the rear axle beam brackets.
Using a wrench, unscrew the bolts securing the holders to the brake flaps.
Now, having disconnected the cable ends from the brake pad drive levers, pull it to remove it from the hole in the brake shield.

After dismantling, install a new Niva rear hand brake cable. To do this, also use these instructions, but perform all the steps in reverse order. And with this, the replacement of the Chevrolet Niva handbrake cable is completed, and finally, do not forget to adjust the degree of its tension. It is also important to lubricate the adjusting threads on the rod upon completion of the repair work to avoid problems with unscrewing the nuts during the next adjustment or replacement.

As on any other car, the Chevrolet Niva parking brake is an integral part of the braking system. Its purpose is to prevent spontaneous movement of the vehicle during parking or temporary parking with the engine running. But the handbrake can also replace the main brake system in the event of its failure, which allows you to safely get to the repair site.

You have to use the handbrake quite often, so its cable and brake pads are subject to intense wear. As a result, car owners over time have to take measures to adjust the system or replace its individual parts. While some people turn to a car repair shop for this, others prefer to carry out repair work themselves.

The design of the Chevrolet Niva parking brake differs little from similar systems in other passenger cars

The design of the parking brake of a Chevrolet Niva is quite simple and is not much different from similar systems in other passenger vehicles. It consists of the following main parts:

Handbrake lever - serves to transmit the force of the human hand to the actuator, which, in turn, acts on the brake pads to lock the rear wheels.
The handbrake cable is a carbide, specially manufactured steel wire that runs under the bottom of the vehicle and operates the brake pads on the rear wheels.
Brake pads are the final elements of the brake system, made of friction materials. By pressing against the brake drum or disc, they immobilize the wheel.

The manual braking system also includes such functional elements as a spacer sleeve, a brake pad drive lever, a spring, a protective sheath for the rear cable, a cover for the front handbrake cable, and a ratchet mechanism for the lever.

The handbrake system contains many structural elements

Description of the Chevrolet Niva handbrake

The parking brake in a Chevrolet Niva, as in other cars, is an important component of the braking system. Frequent use of the handbrake leads to wear on the cable and brake pads. Therefore, over time, it is necessary to carry out repairs and replacements of worn-out parts of Chevrolet Niva parking brakes.

The parking brake serves for:

Parking a car on slopes or slippery terrain.
Temporary parking of a car, without turning off the engine.
Additional braking.
In case of failure of the main braking system.

The Chevrolet Niva parking brake has the same design as on all other car models. The design consists of the following parts that make up a single integral braking system for the rear wheels of the car:

The handbrake is a lever that is activated by the efforts of a person’s hand, thereby bringing the rear wheels into a locked state. The handbrake consists of a lever, which is about 15 cm long, and covered mainly with decorative materials. The handbrake is located in the Chevrolet Niva (as in all cars) between the driver and passenger seats. It is activated by smoothly pulling the lever towards you. Return to the reverse position by pressing the button and smoothly move it down until it stops. The handbrake has from 3 to 7 squeeze (click) positions, it depends on the tension of the cable. The handbrake operates on the principle of a ratchet mechanism. If the brake cable is loose, the lever is tensioned up to 7 clicks.
The tension cable is a special steel wire made from a special carbide material that operates the brake pads. The length of the cable on Niva is approximately 2 meters. And it is located under the bottom of the car, sometimes hidden in a rubber or plastic shell.
Brake pads are an arc (backing) with a special layer (friction plate) that is pressed against the wheel rim, thereby blocking the wheel. Such pads are placed under the wheel rim and are hermetically sealed to prevent the entry of dust, dirt or moisture, which will lead to disruption of the handbrake and damage to its elements. Brake pads wear out quickly when the handbrake is used frequently while driving and require subsequent replacement.

Parking brake adjustment

Adjustment is carried out periodically or if a weakening of the tension cable is detected. It is not difficult to find out that the cable is loose; you will feel that the handbrake does not hold the car in various inclined planes. You can adjust the tension cable and, accordingly, the brake system itself by performing simple sequential steps. It is necessary to drive the car into the inspection hole, or you can do without it, but it will not be very convenient.

To do this, set the handbrake lever to its extreme position towards the floor. In this position of the handbrake, the rear wheels should rotate freely. After this, we lower ourselves into the inspection hole and begin adjusting the cable tension. It is necessary to first unscrew the lock nut with a thirteen wrench, and then begin to tighten the main adjusting nut, while counting the number of turns made.

Tighten the cable three to four turns of the nut, after which you need to squeeze the lever and check at what click the handbrake keeps the wheels stationary. The handbrake is considered normal when the wheels lock at the fifth click. Wheel locking is checked by trying to move the car. After the cable is adjusted, it is necessary to tighten the lock nut all the way to the main nut, and after this the hand parking brake can be considered working.

How to check and adjust the tension of the handbrake cable

If the parking brake is able to hold the car stationary on a 25% slope, then it is doing its job as expected. If you pull the handbrake lever seven ratchet clicks or more, but the car still rolls, the conclusion is the following: the handbrake system is not working effectively.

In such a situation, adjustment of the Chevrolet Niva hand brake is required. This type of repair is simple, performed relatively quickly and does not require the use of special equipment. All you need for work are two keys “12”, pliers and a jack if it is not possible to put the car on the inspection hole.

To work, you need to put the Chevrolet Niva on the inspection hole

First, check whether the handbrake really does not hold the car on the road at a slope of 25%. To do this, place the vehicle on an overpass or find a suitable section of road. If the problem occurs, then we proceed to adjustment.
Setting the optimal parking brake cable tension is done under the car, so it is better to place it above the inspection hole. If this is not possible, use a lift or jack. In any case, the rear of the car must be raised.
When the vehicle is ready for use, secure it and release the handbrake lever.
Next, using a wrench, loosen the lock nut on the handbrake adjusting rod, then use a second identical wrench to tighten the adjusting nut until the cable is properly tensioned. By the way, pliers are needed to keep the rod from turning during the adjustment process.
Now tighten the locknut and make a full stroke first to the working position, and then lower it. After this, spin each rear wheel by hand. The rotation must be uniform, jerking is not allowed. If any are felt, adjusting the Chevrolet Niva handbrake requires repeating.

After assembly, the handbrake must be tested in road conditions.

Parking brake adjustment

How to tighten the handbrake on a Chevrolet Niva, given that loosening its cable can lead to serious trouble? First of all, let's understand the basic parts of the parking brake.

Its structure (main details):

The release of the handbrake in a Chevrolet Niva is checked as follows : you need to drive up a slope and pull the handbrake lever towards you until it stops. If the lever makes 5-7 clicks and securely locks the car, then there is no need to adjust it. And if there were more clicks, but the car is still not fixed, it means that the second cable needs to be tightened.

It's done like this:

Attention! The setting and operation of the parking brake is considered normal if the lever is tightened by 5-7 clicks and at the same time securely fixes the wheel (you can check this by driving onto a slope). After the handbrake lever is lowered to its lowest position, there is no extraneous sound when turning the rear wheel.

Replacing a short handbrake cable on a Chevrolet Niva

As I wrote earlier, slowly but surely, my handbrake cable was getting damaged, and the cable jacket was calloused. Finally, it got warmer outside from -25 to -3, and it was stupid to miss the last days of vacation.

I didn’t think that you might not find spare parts in stock for a Russian-made car, but ShNG is a different story. I drove around all the shops in the city, and everywhere I say that I have one cable like on 2106 or 2121, they stare at me and either snub 2 cables, or try to sell me from 21 Niva.

A week ago, I poured motor oil into the cable jacket and hung it so that it spread along the entire length. On the third day, it started dripping from the second end of the shirts, which means everything was lubricated as it should. Now the cable will not freeze if water gets inside, and it will not rot either. I also cut the springs on the cables, an old technique worked on the nine and six, why not do it on the field.

When replacing everything is standard, we hang up the axle, take off the wheels, take off the drums, but here’s the problem. The old owner left a gift, where there should be a threaded hole for removing the drum, a piece of a bolt sticks out, and it was not possible to tighten it with one bolt until I heated it with a gas burner. Upon further inspection of the drum, I find a second jamb.

The cable served 120 thousand kilometers in 2 years 8 months, which is not bad in principle) For the last 2 weeks I drove without a handbrake - it’s somehow unusual, so today I replaced the old tired cable. Since the BBC did not have a cable for the shniva in stock at that time, I bought it The officials sold it for 400 rubles; in the store it would have been 70 rubles cheaper. Special thanks to Ivanokk, who kept up the conversation in the garage and poured fresh kvass into the mug)

First, remove the spring and unscrew the locknut and nut that tension the cable. Remove the washer and guide plate. If the tension nut does not unscrew, but turns together with the front cable, use WD 40 to help and hold the front cable with pliers.

We counter, install the spring, rejoice at the working handbrake))

The mechanically actuated parking brake system acts on the brake mechanisms of the rear wheels.

The parking brake is mechanically driven from lever 1 (Fig. 1).

The middle part of the rear cable passes through the groove of guide 7, the tension of which is adjusted with a nut screwed onto the threaded end of the front cable.

All models under consideration are equipped with an airbag. The airbag is constantly in an “alert” state and can operate (inflate) at any time when the battery is connected. To prevent accidental airbag deployment (and resulting injury), turn the ignition key to the LOCK position and disconnect the negative cable from the battery whenever performing any work on any safety system components. After disconnecting the cable from the battery, wait at least two more minutes before proceeding (the system is equipped with a capacitor that takes time to discharge). For more information about the operation of the security system, see Chapter On-board electrical equipment system.
