How to tighten the handbrake of a VAZ 2107. Adjusting the handbrake
Locking the wheels when parking a car is the task of the parking or hand brake. It is more often used on bumpy road sections.
A well-adjusted handbrake should lock the car in one place when tightened by 4-6 teeth with a surface slope of 25%. If this does not happen, the parking brake needs to be adjusted or repaired.
The breakdown of the handbrake is a common occurrence, since it is enough to just start the car without removing it from the handbrake. In this case, the pads will wear off and will no longer reach the brake drum.
Reasons for failure of the VAZ 2107 handbrake
Most likely, the cause of the breakdown lies in a stretched or unadjusted handbrake cable. A tightening should be performed if the car does not lock even after 5-7 clicks. This procedure on a VAZ 2107 can be done no more than 4 times, after which the brake pads will need to be replaced.
Another source of handbrake malfunction may be cable looping due to moisture, rust, or dirt that gets on the cable while moving. This can be eliminated by cleaning the cable and lubricating it. If after some time the breakdown occurs again, the handbrake cable 2107 needs to be replaced .
Replacing the hand brake cable of a VAZ 2107
The operation of replacing the cable is carried out on a lift or inspection pit.
To replace the handbrake cable, it is necessary to remove the brake drums of the rear wheels. When removing them, it is possible to check the condition of the brake pads and parts of the brake mechanism, especially the working cylinders. The latter should not have any traces of brake fluid leakage, and the rubber boots should not have cracks or damage.
Removing brake drums is a rather complicated procedure. The work is made difficult by the wear of the brake drum, which, as a result of wear, may have a “side” that clings to the pads when removed. Another problem is corrosion, which is best combated with WD-40.
When removing the brake drum, you can use a sledgehammer or hammer, but the blows must be applied through a wooden block. Without the use of a block, the hammer may crack the aluminum edges of the drum.
When the drum is removed, the brake mechanism should be inspected and cleaned of dirt. The wheel hub should be lubricated with graphite grease. If the brake pads are on the verge of complete wear, they should be replaced.
To replace the VAZ 2107 parking brake cable, you need to unscrew the two mounting bolts, release the cable and remove it.
After removing the old cable, all that remains is to install a new one and put the brake drums and wheels in place. After which it is necessary to adjust the VAZ 2107 handbrake as described in the previous paragraph.
Now you know how to repair the VAZ 2107 handbrake.

In addition, to correct the breakdown, it is necessary to remove the jamming defect of the handbrake lever, and perhaps also the ratchet mechanism of the ratchet.
Therefore, before repairing the handbrake, you should make sure that it is adjusted correctly and that the cause of the problem is not in the cable. At the same time, the technical condition of the rear brakes, cable, and handbrake drive must be good.
Required tools:
- 2 keys for “13”;
- pliers;
- jack.
Replacing the handbrake and front parking brake cable on a VAZ 2101-VAZ 2107
Welcome! There are two cables in total in the car, namely the rear and front handbrake cables. The front one, coming from the parking brake and having a short length. It goes to the rear, compared to the front cable it is very long. The rear one goes directly to the two rear wheels. Thanks to the cable system, the car is braked.
Note! You will have to remove the handbrake, which means the following tools will be useful: various kinds of wrenches, a screwdriver and pliers.
Part location
It comes from the handbrake and passes under the bottom of the car, connecting to the rear (main) cable. Below we have attached a photo with a diagram of the handbrake. The front cable is indicated by number 2.
Note! In the diagram above it may seem that cable number two is divided into two parts, but in fact it is not. It is solid, just in the place where it supposedly breaks (in the diagram) there is a roller (indicated by number 8).
When to change the cable and the handbrake itself?
You have to change it when the cable breaks. You will feel this when the handbrake begins to rise very easily and to a very high position, almost to a vertical position. Exactly the same situation will arise if the cable breaks at the back. Therefore, before you go to a car store and buy a new one, inspect the bottom of the car and figure out which cable has become unusable.
Note! The cable tends to stretch over time. It all depends on the quality of the material; a high-quality cable will last longer and stretch to a shorter length. If you see that this cable is sagging and the adjustment does not lead to anything good, then you will have to replace it with a new one!
How to tighten the handbrake of a VAZ 2107 yourself
- Place the car on a viewing hole or lift.
- Jack up the rear of the car, hang the rear wheels (they should rotate freely).
- Tighten the handbrake to the locking position (5-7 clicks).
- Remove dirt from the adjusting bolt and handbrake nuts.
- Using keys “13”, tighten (or loosen) the nut that adjusts the tension of the handbrake. It is worth pulling until the free rotation of the wheels stops (at this time you can make sure that there is no play or friction).
How to tighten the handbrake of a VAZ 2107. Adjusting the handbrake
- After tightening the adjusting nut and locking the wheels, you need to tighten the adjusting nut completely. This will reduce the free play of the handbrake.
- Make sure the wheels brake, then tighten the locknut.

- Lubricate the threaded holes (optionally, “Litolom” lubricant).
- Make sure that the protective sheath of the hand rope is not damaged.
This the tightening of the VAZ 2107 handbrake . All that remains is to lower the car from the jack and check the handbrake in action.
Why the handbrake does not work on the VAZ 2107
Like any other part or mechanism, the handbrake cable tends to wear out and become unusable. The parking brake on the VAZ 2107 is activated using a lever located in the middle part of the car between the driver and passenger seats.
Periodically, the handbrake cable should be tightened, as it becomes weakened, which leads to a decrease in the efficiency of the device. The reasons why the handbrake on the “seven” may not function are due to the following factors:
- Excessive cable stretch.
- Damage to the cable.
- Malfunction of the brake mechanism in the rear wheel drums.
During prolonged use of the car, when the handbrake is constantly used, owners are faced with the need to periodically restore the cable tension. Over time, the device in question stretches, and there is nowhere to tighten it. The only way out of the situation is to exchange the product for a new one. It is recommended to carry out work on replacing the handbrake cable in an inspection hole, but you can do without it.
Changing the handbrake cable
Replacing the handbrake cable on a VAZ 2107 car begins with the fact that it is first necessary to dismantle the brake drums of the rear wheels. After dismantling the brake drums, you should pay attention to the condition of the rear brake pads and working cylinders. The presence of traces of fluid leakage will indicate that the mechanisms also need repair.
Each owner of his car decides individually when it is necessary to change the handbrake cable. It all depends on the degree of wear of the cable. The procedure for replacing the parking brake cable is divided into 2 stages: dismantling and installation, as well as adjusting the tension.
The replacement algorithm is as follows:
- After the rear wheels and brake drums are removed, you need to go down into the inspection hole and find the tension adjusting rod. This rod is equipped with a spring, which must be removed using a screwdriver.
- Both nuts are unscrewed, after which the adjustment bar is removed. Next, the rear and front handbrake cables are dismantled.
- Using a wrench, you need to unscrew the two nuts securing the two brackets. These brackets prevent the cable from falling. There are screws under the nuts that prevent them from unscrewing on their own.
- After this, you should remove the rear brake drums and remove the springs that secure the brake pads. The pads can also be replaced if they show excessive wear.
- Next, you need to pull the cable to disengage it from the bracket against which it rests.
- The brake pads are removed. There is no need to remove both pads on the wheel. To replace the rear cable, you only need to remove one rear brake pad.
- Now you should unscrew two fixing bolts from the back of the brake shield of both wheels. With their help, the cable tip is fixed. After unscrewing these two bolts, you should pull the cable, as shown in the photo below.
- Using a 10mm wrench, you need to unscrew the front cable mounting brackets. After unscrewing the bolt, carefully remove the roller. To remove the roller, you need to roll it forward in the direction of the tip.
- To remove the front part of the device, you need to pull on the product to remove it from the bracket and intermediate support structure.
- After this, you need to get out of the hole and go into the car interior. When performing work, the handbrake must be in its lowest position. Inside, unscrew the two screws securing the handle trim.
- There are 4 bolts under the cladding that need to be unscrewed. After unscrewing them, you will need to remove the handle along with the front cable.
- To disconnect the cable mount from the handle, you will need to use pliers to remove the small cotter pin that secures the device to the handbrake handle.
- After this, the device can be completely removed from the car and a new cable installed in its place. The installation process of both products is carried out in the reverse order of removal. After this, you should secure them and begin the tension adjustment procedure.
It is important to know! When installing the rear cable, it is important to know the following: this element has right and left sides. On the right side there is a rubber tube, which acts as additional insulation of the braid from the nearby hot resonator pipe.
Adjusting the hand brake VAZ 2107
Adjustment of the handbrake should be performed not only periodically when the parking brake is lost, but also after replacing the cable. In order to adjust the cable tension, you will need to take the following tools:
- pliers;
- two keys for 13;
- a can of WD-40 lubricant.
Features of the braking system
One of the features of the VAZ-2107 brake circuit is the presence of a dual-circuit system. The essence of a dual-circuit system is that the working drive is divided into two parts, each of which supplies fluid to only two mechanisms, while the circuits do not interact with each other.
The presence of two circuits ensures the operability of the brakes of at least two wheels in the event of depressurization of one of the circuits. That is, even if the pipelines of one circuit are punctured, the second will remain fully operational, which will ensure the functioning of the brakes.
In the VAZ-2107, the circuits are divided in such a way that the drive of the front axle mechanisms is separated from the drive of the rear mechanisms. This allows you not only to maintain the functionality of the system when one of the circuits fails, but also to pump each circuit separately. That is, if one of the circuits is airy, then it needs to be pumped, but it is not necessary to service the second one.
This is only general information about how the VAZ-2107 brake system works, and does not include all the details on its maintenance and repair. In general, the brakes of this car work quite well, although some elements of it cause complaints from car owners.
