The parking brake in the people is called the handbrake, and it serves to keep the vehicle in one place for a long time. Apply it during the parking lot, stop on the road with a bias and for the implementation of sharp turns on sports cars with rear-wheel drive. The parking brake system is also an emergency or spare system, because it completely copies the hydraulic operating system. Using the parking brake in an emergency situation (for example, when the brake fails), while driving, it makes it possible to bring the car to a complete stop.

Parking brake how to check its performance

In the brake parking system, a mechanical brake drive is mainly used, providing the transmission of the brake force to the braking mechanism from a person. A person interacts with a foot pedal, a pull or manual lever. The most common mechanism is a manual lever, which is usually located next to the seat on the right of the driver. The hand lever is equipped with a ratchet mechanism that fixes the parking brake in the working position. On this lever there is a handbrack control lamp switch. The lamp itself is mounted on the dashboard and turns on while the parking brake is triggered.

On transport with disk brakes, the following designs of the brake parking mechanism are used - drum, cam and screw.

Checking the performance of the parking brake must be regularly (preferably after every thirty thousand kilometers of driving), since the handbrake may be in working condition, but it is very weak to keep the car, which can lead to the rolling of the vehicle from the slope and the creation of an emergency. This is especially true for cars that are exploited for a long time.

To check the handling performance, you must put a car on a small slide with an approximate slope of 25 percent. After that, it will be necessary to stop, pull the hand brake up to the stop, turn on the neutral transmission, release, while the brake pedal. If the vehicle continues and does not roll down, then there is no need to adjust the parking brake.

If there is no similar slope nearby, you can check the status of the parking brake in another way. To do this, put the transport on a flat surface, after which it is necessary to pull the handbrake and put into the neutral position of the gear shift handle. Now exit the car and try to push the vehicle yourself. If it moves from the place, then the parking brake works weakly.

In addition, there is another method of checking the parking brake. To do this, it is necessary to tighten it before the failure, turn on the first transmission and slowly release the clutch. If the device works normally, the vehicle's motor must be stuck. Otherwise, the car will begin to move very slowly, which indicates the need to adjust the handbrake or replace the cable.

Choice of workplace for adjustment

The adjustment process must be carried out on some elevation - the overpass, lift or observation pit. In the extreme case, you can apply a jack, and under the back of the vehicle to install goats. Pay attention to the instruction manual for the vehicle, as for some parking brake systems, the adjustment should be carried out in the cabin.

Tools assistants

To adjust the parking brake, you will need such tools and materials:

1. Horn keys for thirteen.
2. Ratchet.
3. Medium extension.
4. It is extremely desirable to purchase WD-40 lubrication.

Handler adjustment, step-by-step instruction

It is necessary to adjust the manual brake in the following cases:

1. If the course of the brake lever increased significantly.
2. If you made a reverse stop of the adjustment device.
3. If you replaced the brake torso in the parking brake.
4. If you adjust the position of the brake pads.
5. If you replaced brake discs.
6. If you replaced the brake pads.
7. If the hand brake has failed.

To resolve problems with the parking brake, you can resort to the help of specialists or adjust the handbrake on your own, as it is quite easy to make it on your own and cope with this for any driver who has at least a basic idea of \u200b\u200bthe vehicle device.

If the parking brake is configured correctly, the number of clicks when the lever is tightened to be five or six. If the number of clicks is greater or less, it means that it is necessary to adjust the parking brake.

Adjustment of the manual brake does not depend on its design and is made according to the principle of adjusting the gaps between the brake drums (discs) and brake pads (lining). This clearance must be adjusted by changing the tension of the parking brake cable, which is located at the bottom of the brake handle under the salon panel.

Tensioning the handbrake is necessary by the following technology:

1. We raise the vehicle and install it on the support for accessing the bottom of the car.
2. Raise the parking brake lever from one to three clicks.
3. We find and weaken the leveling of the equalizer through the hole of the brake drum.
4. Watch the adjusting nut and follow the tension of the brake cable.
5. If the cable tension did not occur, it is necessary to replace the parking brake cable as quickly as possible.
6. If the tension passed normally, it is necessary to check the working capacity of the manual brake, for which it is necessary to pull the handle on itself. After that, we try to twist the back the wheel. It should rotate with difficulty. Now tighten the lock nut, let go of the parking brake lever and turn the rear wheel again. In this case, it should spin freely.
7. At the last stage, it is necessary to lower the vehicle to the ground and check the work of the handbrake under the optimal driving conditions.

Hand brake cable, cable replacement, step-by-step instructions

To replace the parking brake cable, you will need the following tools and materials:

1. Jack.
2. Balo key.
3. Screwdriver.
4. Passatia.
5. Caid key.

Operating procedure:

1. First you need to drive the vehicle to the observation pit, the overpass or lift.
2. Then you need to clean the surface of the nut and the equalizer.
3. Next, weaken the lock nut and unscrew it.
4. We also do with the adjusting nut.
5. Let the back of the vehicle - weaken the wheelbats, raise the car jack and put the supports. Lower the vehicle and remove two wheels.
6. We remove the brake drums - turn the wheel stiletto and knock them off the shoe with the help of a hammer.
7. Remove the rear block to which the tip of the parking brake is attached. After that, we remove the tip itself.
8. We turn off the bolt, with which the cable sheath is attached to the rear suspension.
9. Pull the sealing sleeves from the shell of the cable, after which I pull out of the holes and it myself.
10. We have a shell from body holders and remove the cable tips from the equalizing panel.
11. Mount the new hand brake cable.
12. We produce parts assembly in the reverse order.

Tips of professionals

As a result, I would like to note that the majority of motorists mistakenly assume that the less often to touch the parking brake, the longer it will work. However, in fact it is not. To ensure the durability of the parking brake, it is necessary to use it more often. If it is rarely used, it will fail much faster as a result of the accumulation of dust, the lack of lubricant, dragged to the shell of the cable and other similar factors that will significantly make it difficult to move the parking brake, which will increase the upcoming load when using it. However, one should not overdo it. If you constantly slow down the vehicle by using a manual brake, it will not lead to good, since its main purpose is still the holding of a vehicle in place.
