You can make a hydraulic handbrake for tuning yourself. VAZ of any model is equipped with a hydraulic brake system, but the parking cable design. This impairs performance, since the cable tends to stretch, so the effectiveness of the handbrake is reduced. And the drum brakes themselves are not very reliable.

Braking performance is extremely poor. But for the full functioning of the hydraulic handbrake, it is imperative that disc brakes are on the rear wheels. The second, negative side - according to the traffic rules, it is forbidden to make changes to the brake system. Therefore, by carrying out such an upgrade, you act at your own peril and risk.

Main purpose

You can independently install and adjust the hydraulic handbrake on the VAZ-2109, having certain skills and tools. Despite the prohibitions, such designs can be found on sale and can be installed on any make and model of a car. All worksit is desirable to carry out on a viewing hole or a lift. With the help of a hydraulic handbrake, you will be able to greatly increase the efficiency of the braking system. The design provides for the presence of a regulator that allows you to distribute the force between the front and rear circuits. The adjuster allows and prevents the rear wheels from completely locking up.

What can a hydraulic handbrake do?

With this handbrake design, you can completely block the rear wheels in order to warm up the rubber on the front axle. It will be useful for racing fans. For ordinary drivers, locking will be useful to reduce the chance of skidding when cornering on wet roads. The device is mounted near the hand brake lever so that it has free access. If the regulator is set correctly, then the force on the rear brake mechanism will be distributed smoothly, and the efficiency of the front ones will increase.

Hydraulic handbrake kit

A hydraulic handbrake kit can be purchased from automotive stores. You can install it with your own hands, but you will need a few more additional elements:

1. 10 copper washers for brake mechanisms
2. Metal tubes in the amount of 5 pcs. To save some money, you can purchase a complete set for Gazelle cars.
3. Plugs.
4. Twists.
5. Brake hoses for VAZ-2101-2107.
6. Tee for brake system.
7. Plastic tie-downs inquantity of 50 pieces
8. Brake regulator for VAZ cars of any model.
9. GTZ for VAZ-2101. If there is none, then any other cylinder can be used.

In addition to all this, you will need brake fluid for subsequent refueling of the system. After all, the alteration includes inserting an additional circuit into the brake lines.

Preparatory work

Before tuning, you need to get rid of the old, imperfect system. To do this, the mechanical drive is completely dismantled. Please note that after installing the hydraulic handbrake, the operation of the caliper drive will completely change. If by default the mechanisms worked in pairs, which are located on wheels located diagonally, then after the alteration the scheme will be axial (rear and front). But before installing the hydraulic handbrake, you need to remove the old one.

How to remove the handbrake cable

To dismantle the old handbrake, you will need to perform several steps:

1. Install the car on a flyover, viewing hole or lift. It all depends on what amenities you have. If there are no such facilities, then it is better not to even start working.
2. Raise the rear of the car on a jack, having previously installed stops under the front wheels.
3. Install supports under the rear beam.
4. Since the hydraulic handbrake can be installed with drum brakes, the design can not be changed much. filmingwheels and drums from rear axle.
5. In order not to interfere, dismantle the resonator and muffler.
6. Remove the equalizer from the rod.
7. Dismantle the cable by removing it from the blocks on both wheels.
8. Now you need to make some manipulations in the car. Open access to the handbrake lever and unscrew the fasteners. Then completely remove it from the seat.

Now you can start installing your new system using one of two popular methods.

Installation Method 1

There are two ways to install a hydraulic handbrake on a VAZ, according to experts. The simplest and most accessible involves the following manipulations:

1. In the engine compartment it is necessary to install another brake cylinder. The clutch master cylinder from a VAZ-2101 car is ideal.
2. Remove the brake fluid expansion tank.
3. You will need to make a small adapter yourself. Cut the thread and install the washer (it should have a thread for the fitting).

Assembling the entire system starts from the native GTZ to the clutch cylinder, then to the regulator, handbrake, rear brake circuit. To connect all the components together, use the tubes from the Gazelle car. Just choose the ones that fit the size. The tubes are fastened to the places to which the handbrake cable was fixed.

Installation method 2

First, you need to do a few manipulations under the hood:

1. Unscrew the tube that goes to the left brake mechanism and put a plug on it.
2. Unscrew the tube going to the front right wheel. Install it in the hole designed for the right rear brake.

Before starting work, be sure to drain all the liquid. Try to do everything carefully so as not to damage the hydraulic mechanisms. Try not to let the liquid get on the metal, as it will corrode it. Next steps:

1. Install a new handbrake between the seats.
2. Install the bolt instead of the pendulum of the regulator. Screw to the bottom of the body. For a while, it is recommended to remove the front seats so that they do not interfere and do not get dirty during work.
3. From the engine compartment, a tube is laid along the bottom to the new handbrake.
4. Lay pipes from the regulator along the bottom in the cabin.
5. Customize the tubes and install them on the rear axle.
6. Attach the flexible hose to the bracket on the rear beam.
7. Be sure to put a rubber ring so that the hose does not rub during operation. Cut this ring to make it easier to put on.
8. Connect the hose to the tubes. Use plastic zip ties to secure metal tubes.

Completion of works by the second method

Be careful not to twist the hose when making repairs. It maycause damage and fluid leakage. First you need to tighten the edge on which the thread is external. After that, the edge with an internal thread is tightened. How to make a hydraulic handbrake yourself? The final stage looks like this:

1. Fix the position of the new system, check the tightness of all threaded connections.
2. Fill the expansion tank with brake fluid.
3. Pump the system according to the scheme from the far cylinder to the near one. Top up the liquid in the tank in time. Otherwise, pumping will need to be done again.
4. Check the braking system. Whether the calipers are squeezed out normally.

After, collect all the disassembled nodes - reinstall the wheels. Before the first ride, make sure the brakes are working properly. If there are problems, fix them right away. On the first trip, do not accelerate to high speed so that you can stop the car at least with the engine. All of the above methods are suitable for installing a do-it-yourself hydraulic handbrake on a VAZ of any model, as well as on cars from other manufacturers (including foreign ones).

Cost of tuning

Now it's time to make a detailed estimate for the parts used during the tuning of the brake system. The price of all components may vary, it all depends on whether you are purchasing new or used ones. Estimated cost:

1. Hydraulic brake assembly - the cost is about 2700 rubles. You can also find cheapChinese copies, but whether to trust them - decide for yourself. The quality of such products is very often at a low level.
2. Regulator - 400-500 rubles.
3. Brake pipes for a Gazelle car - 300-400 rubles.
4. Clutch cylinder (main) for the classics - about 450-500 rubles.
5. And small consumables - copper washers, plastic clamps, ties, brake hose VAZ-2101, fluid - spend about 500-600 rubles on everything.

By modest standards, the cost of tuning will cost about 5,000 rubles. If this is a lot for you, then abandon this idea and simply install a new handbrake cable instead of the stretched old one. It is recommended that before starting work, read the advice of specialists, talk with those who have already done similar work. They will be able to give you a lot of practical advice regarding the improvement of the braking system on a particular car.

Do I need rear disc brakes?

The answer is ambiguous, since disc brakes have clear advantages over drum brakes. If you are already doing system tuning, then do not be lazy and put discs on the rear axle. Their advantages are even in small things - it is much easier to replace the pads than on drum pads (and the cost of the kit is lower). Wheels from model 2109 are ideal for the rear wheels of VAZ cars with front-wheel drive. Alterations to a minimum, everything becomes as if “native”. But if your budget for tuning is limited, then you can use the standard system. Drum brakes are relatively goodwork, and the use of hydraulics will forever save you from having to tighten the cable. And under any slope, the car will stand normally without rolling.

Conclusion

This revision is very interesting, and anyone can do it, since there are plenty of materials and tools for this on sale. In addition, you can buy a ready-made kit for a particular car, which will include not only a hydraulic handbrake, but also all tube and hose systems, all that remains is to connect everything and bleed the brakes. The cost of such a design will be higher, but the reliability will be good. If you think that you will not be able to master the work, it is better to refuse it and give the car to experienced craftsmen who will do everything at the highest level. After all, your life and he alth depend on the quality of the brakes.
