The parking brake must always be in working order, if you begin to notice any malfunctions, you should immediately start repairing. Today we will publish a guide that describes in detail the repair of the hand brake on the Lada Priora with our own hands.
1. The first step is to disconnect the wire from the “-” terminal of the car battery.
2. Remove the lining of the floor tunnel.
3. From the bottom of the car, using a key "13", unscrew the lock nut and the parking brake adjusting nut and remove the equalizer 1 from the rod 2.
4. Remove the protective cover from the hole in the floor and remove it from the tie rod.
5.From inside the passenger compartment, remove the screw for the front fastening of the bracket for the parking brake warning lamp switch. Please note that the ground wire of the switch is secured with a screw.
6. Using a “10” wrench, unscrew the four parking brake lever fastening bolts (two front ones also fasten the switch bracket).
7. Set the switch bracket aside.
8. Remove the parking brake lever by pulling the link out of the hole in the floor.
9. To replace the rod, remove the cotter pin 1 and remove the washer 2.
11. Replace a worn or cracked plastic bushing. Assemble and install the parking brake lever in the reverse order of disassembly. After installing the lever, adjust the parking brake.
The parking brake is one of the key elements of the entire braking system. Any motorist realizes the exceptional importance of this device. When the unit fails, it is not worth delaying the repair. The serviceability of the system is an important condition for the safe operation of the car. We will tell you how to tighten the handbrake on the Priora or replace the parking brake.
Wear of brake pads, like other elements of a car, is inevitable. For this reason, the cable must also be tightened regularly. During normal vehicle operation, the frequency of adjusting the brake system is every 20-30 km. mileage. To set up, you need two open-end screwdrivers. Work is best done in a garage pit or on an overpass. Before starting the operation, we clean the bottom of the car from dirt.
If the adjustment of the cables did not give the desired result, change the parking brake.
After work, all elements must be well lubricated. This measure will protect components and assemblies from corrosion and extend their service life.
Rear brake pad wear is inevitable, which is why over time you have to tighten the parking brake cable for the parking brake to work effectively. On the Priora, as well as on other front-wheel drive cars of domestic production, the adjustment is carried out in the same way, and to complete it you will need only two keys for 13, preferably open-end.
To look at all this work visually, I recorded a video lesson that will show this process in as much detail as possible.
This work was done on the example of a dozen, but the only difference that can be is the installation of a protective metal screen on the Prior, which must first be removed.
VIDEO Below there will be a photo report in case of unavailability of viewing a video clip.
This procedure is most conveniently carried out on a pit or hoist to get to the adjustment mechanism without too many problems. In the back of the car, under its bottom, you need to find such a mechanism, which is shown below in the photo:
So, the first step is to remove the heatsink, if any. It usually rests on 4 nuts. Then we loosen the lock nut and tighten the first one until the handbrake works effectively. Usually it should block the wheels of the car well with 2-4 clicks of the lever.
When the cable is properly tensioned, the lock nut can be tightened and the protective shield replaced. It should be borne in mind that you should not overtighten the cable, as this can lead to rapid wear of the rear pads and excessive heating of the drums.
If, even with a sufficiently strong tension on the parking brake cable on the Priora, no improvement occurs, then it is necessary to replace the pads.
Operations performed when repairing the parking brake lever on a VAZ 2170 2171 2172 Lada Priora
The parking brake lever is a brake system and not only the operation of the brake system during parking, but also your safe movement depends on its serviceability. So, in particular, with the help of the hand brake, the rear brake pads are exposed, in the event of a malfunction of the hand brake system, the rear brakes may not be provided with the proper efficiency.
You will need: two "13" wrenches, a 13 "socket wrench (head), a Phillips screwdriver, pliers.
The tool necessary for repairing the handbrake on a VAZ 2170 2171 2172 Lada Priora
1. Disconnect the wire from the negative terminal of the storage battery.
3. From the bottom of the car, using a key "13", unscrew the lock nut and the parking brake adjusting nut and remove the equalizer 1 from the rod 2.
4. Remove the protective cover from the hole in the floor and remove it from the tie rod.
6. Using a “10” wrench, unscrew the four parking brake lever fastening bolts (two front ones also fasten the switch bracket).
8. Remove the parking brake lever by pulling the tie rod out of the hole in the floor. 9. To replace the rod, remove the cotter pin 1 and remove the washer 2.
Additionally, you can see an article about a similar hand brake system on cars of the tenth family "Removing units and adjusting the parking brake system VAZ 2110 2111 2112"
Parking brake lever travel should be 2-4 clicks. During the operation of the car, it is allowed to increase the lever travel up to eight clicks.
If the lever travel is six or more clicks, adjust the parking brake actuator.
To complete the work, you will need a viewing ditch or overpass.
1. Preparing the car for the job.
2. Raise the parking brake lever up to the stop, determining the amount of its travel. If it is less than two clicks, lengthen the drive, and if more than six, shorten it.
3. Fully lower the parking brake lever.
4. Remove the pillows from the brackets of the additional muffler.
5. Pulling the additional muffler away from the bottom of the car, place a wooden block under the muffler pipe. We remove the protective screen.
7.Loosening the adjusting nut lengthens the drive, tightening it shortens it.
8. Periodically, during the adjustment process, we check the lever stroke.
If the length of the threaded part of the rod is not enough to adjust the lever stroke, it is necessary to replace the drive cables, and in case of severe wear of the linings and brake pads.
9. After adjusting the parking brake lever, we hang the rear of the car. We check the ease of rotation of the rear wheels and the reliability of their fixation with the parking brake.
10. If the brake pads do not interfere with the rotation of the wheels, fix the adjusting nut with a locknut. Install the protective screen in place.
11. We check the performance of the parking brake system: on an incline with a slope of 23%, it must reliably hold the car at a standstill. If necessary, we check the condition of the parking brake drive parts, the condition of the rear brake pads and brake drums. We replace defective and worn parts. Then we repeat the adjustment.
I somehow tightened the cable so that the car could not move :)

We replace the parking brake cables when they break, pull or jam inside the shells, when adjusting the parking brake fails to keep the car stationary on a slope - up to 25% inclusive. We remove the parking brake lever to replace it or to replace the lever arm.
Remove the cable equalizer from the parking brake lever pull.
We take out the front ends of the cables from the equalizer and remove the equalizer.
We take out the end of the shell of the left cable from the bracket.
The cables cross in front of the bracket.
With a head or a key "for 10" we unscrew, not completely, the nut that secures the bracket to the rear suspension beam ...
We remove the sheath of the cable from the holder on the bracket for attaching the rear suspension beam.
Bend the bracket with a screwdriver ...
We take out the cable from the second holder located on the body in front of the fuel tank.
We remove the tip of the cable from the hole in the brake shield ...
Using the "10" head, unscrew the four bolts securing the parking brake lever bracket to the floor tunnel.
Remove the parking brake lever with bracket and rod assembly by pulling the rod through a rubber sealing cover in the bottom of the body.
We straighten the cotter pin with pliers ...
Remove the washer, axle and tie rod from the parking brake lever.
If on the VAZ-2112 it has become bad to hold the handbrake, then you should not immediately change it, since the cable can be adjusted. In the event that the mileage on the car is large, the rear pads on the car may wear out.This can lead to a decrease in the effectiveness of the handbrake and the entire braking system. In this case, the handbrake cable will need to be tightened.
For clarity, we give a diagram of the hand brake
1 - a button that fixes the parking brake lever; 2 - hand brake lever; 3 - protective pad; 4 - handbrake traction; 5 - cable equalizer; 6 - adjusting nut; 7 - lock nut; 8 - cable; 9 - protective sheathing of the cable.
In this scheme, we need item number 6 ... It is he, and only he!
In order to adjust the handbrake, you need an overpass or a lift. If there are no such devices, then you can simply hang the rear wheels on the "trestle". They can be installed under the car using a jack. It is also worth taking two keys for "13" and pliers.
The car is installed on a flyover or "goats".
We put the handbrake at the very bottom. Do not pay attention to the scuffs of the console, we conducted an experiment with non-standard armrests. The iron mounts of the armrest are visible. On the photo is the editorial car
We tighten the adjusting nut
Everything is rusted with us, we have changed the adjustment mechanism
If it does not come out to pull the cable, then it should be replaced with a new one.
After adjusting the brakes, check them again. To do this, the car should be placed on a road with a slope. not less than 23% ... The car should be in neutral in this area and with the handbrake tightened. If the handbrake brakes hold the car in this area, then the handbrake is adjusted correctly.
There are also cases when the above actions are not enough to adjust the handbrake. This can happen, for example, when the handbrake cable is cut off. This happens on the VAZ-2112, although rarely. In such situations, the cable must be replaced. Also, the cable must be replaced when:
Tips are loose.
The cable itself begins to stretch, which will lead to its breakage during operation.
HAIKU! The old cable is very worn out! For comparison, the old and new parking brake cables
Strong wear of the parking brake cable
Such a replacement procedure does not require contacting a service station. Although it will take some time and skills from the driver, you can do this work yourself.
It should also be remembered that certain conditions must be observed when replacing the cable. To do this, the driver will need an assistant who will pull the cable.
The cable acts as a drive here. If the driver pulls the handbrake lever, then at the same time he uses the cable, which spreads the pads in the rear wheel.
If the handbrake is faulty, then you just need to tighten the cable or replace it with a new one. On the VAZ-2112, it is quite simple to do it with your own hands.
You can determine if the parking brake needs adjustment by checking. It is recommended to do it every 30,000 kilometers. This procedure should be done even when it seems that the handbrake is working well.
Also, the device must be checked in cases where it does not work. For example, a car is moving when the brake lever is applied.

Car brake pads are susceptible to gradual wear, in connection with which it is necessary to periodically check the operation of the parking brake, and, if necessary, tighten its cable. On Priora, the parking brake cable is tightened in the same way as on other front-wheel drive cars of domestic production.
And in order to do this work, you just need two keys for 13, preferably open-end.
In order to more clearly see how the whole process should go, you can watch the video review

In case you still have any questions after that, you can see the photo countdown for the video.
It is advisable to do all the work on a pit or on a lift, since in this case it will be much easier for you to get to the adjustment mechanism. In the back of the car we find the mechanism shown in the photo below.
So, first of all, you will need to remove the heat sink, unless of course it is on your car. As a rule, it is kept on 4 nuts. Next, you need to loosen the lock nut, after which we tighten the first one until the parking brake cable is pulled up to the desired level. Usually, the wheels of the car lock occurs with 2-4 clicks of the lever.
After that, we tighten the lock nut back and install the protective screen in place. With all this, it is also worth noting the fact that it is also not recommended to overtighten the cable, since the consequences of this can be rapid wear of the rear pads and excessive heating of the drums.
After completing the operation, check in action whether the adjustment was performed correctly.
In cases where, even after a strong tension on the cable, nothing has changed, then it is necessary to replace the brake pads.
To check the condition, or rather the robotic ability of the handbrake, we set the car on a slight slope. If by 3-4 clicks the tightened hand brake lever keeps the car on a slope, then you did everything right.
Repair of the hand brake lever on the Lada Priora car is performed in the case when it has ceased to perform the functions assigned to it. Depending on the severity of the damage, the lever is either changed or restored. The car must be driven onto an inspection pit, overpass or lifts. To carry out repair work, prepare a standard set of tools, then do the following sequence of actions:
First of all, it is necessary to de-energize the car; for this, disconnect the minus terminal from the battery. To prevent a short circuit and damage to the fuses when disconnecting the power wires from the parking brake sensor.
In the passenger compartment, dismantle the decorative tunnel located directly between the front seats.
Next, we move under the bottom and with two wrenches, one of which we keep from turning the adjusting nut of the drive cable, and the second we unscrew the counter nut, after which we completely unscrew the adjusting nut and disconnect the cable from the equalizer.
Remove the protective rubber boot from the rod. Subsequently, during assembly, if it is damaged, replace it with a new one.
Inside the car, near the handbrake lever, unscrew the screw for the front fastening of the bracket for the parking brake indicator switch button, also under this screw there is a ground wire.
Now you can remove the lever mechanism itself. To do this, with a socket head for ten, unscrew the four bolts of its fastening to the body. The two bolts are also used to secure the switch bracket.
Set the bracket with the switch aside so that it does not interfere.
The mechanism itself with the lever can now be removed.
To replace the drive rod, release the tabs on the locking cotter pin.
Now you can remove the rod from the axle and the plastic washer located under it. If the washer is damaged, replace it.
