In detail: do-it-yourself brake hose repair from a real master for the site my.housecope.com.
A working braking system is a guarantee of your safety! I spoke about this for a long time, in one of my previous articles. Today I am no less sure of this, and I want to talk about brake hoses, or rather, how to replace them with a VAZ 2115.
Only regular maintenance and monitoring of all components of the braking system can provide confidence that the brakes will not fail at one most inopportune moment. One of the most important components of the brake system (TS) is the line through which the brake fluid (TZ) is delivered to the brake cylinder and calipers. Violation of the tightness of one of the hoses can lead to a malfunction of the vehicle, as a result of which the TJ will leak out, and you will simply find yourself without brakes.
Replacement of brake hoses is regulated by each manufacturer differently, on average it is 3-5 years or about 100 thousand kilometers. However, all this is individual, hoses can fail earlier and later, it all depends on the operating conditions and the quality of the brake hoses themselves. It is necessary to visually inspect the hoses from time to time, and the entire vehicle as a whole, this is the only way you can avoid troubles on the road.
The appearance of microcracks on rubber hoses or metal pipes is a reason to immediately replace the brake hose or part of the damaged line. Damage to the tightness of the line manifests itself in different ways, one thing will always be the same - the absence of brakes, that is, pressing the pedal will fail, and the car will not stop. Hose damage can also be detected from a wet track after long periods of parking.

In my article today, I will tell you about how to replace brake hoses on a VAZ 2115 at home.
New brake hose (s);
Special key for removing brake pipes with a double clamp “9x11”;
A set of keys (8, 10 15);
Adjustable wrench;
Jack;
WD-40 liquid.
The first step is to establish the location of the damage and decide which of the hoses you need. In this case, the front brake hose burst. Then we buy everything we need and get to work. The photo shows the place of rupture (damage).
We start by ripping off the wheel bolts while the car is on four wheels, then jack the side we need, unscrew the bolts and remove the wheel.
We process the WD-40 bolts and wait for the liquid to eat away the rust, and will allow you to easily unscrew the connection.
Next, we unscrew the hose connected to the metal brake pipe. Using the key on “15”, we hold the tip of the hose, and with the other key on “10”, carefully unscrew the union of the brake pipe. It is important here to be as careful as possible, as it is very easy to rip off or “lick off” the edges. If the nut does not give way, use a special brake hose wrench. Such a key allows you to tighten, making it more firmly engaged between the key and the threaded connection.
After the connection is unscrewed, the tube should be plugged with something suitable in diameter, this is necessary in order to avoid leakage of the TAS.
Now, using the “15” key, unscrew the hose fitting connected to the brake cylinder. A copper ring is installed between the cylinder and the fitting, which it is desirable to replace, but if it is in order, then you can do without it.
Then we assemble in reverse order. However, it is too early to put an end to this. Before enjoying the work done, it is necessary to bleed the brake system in order to expel all the air that has entered the vehicle.I will not tell you how to bleed the brake system, you can read about this in one of my previous articles - here is the link to this article
After bleeding the brake system, we check the tightness of the joints and the level of TJ in the system. Next, we check how everything works. I warn you, do not rush to accelerate strongly to test the brakes, anything can happen, if the brakes fail, you can make an accident and damage your own or someone else's car. First check how everything works somewhere in an uncrowded place at low speed, if everything is ok, check how the car will behave on an empty track.
That's all for me, thank you for your attention, until we meet again at the VAZ Repair. If you liked this report, share the link to the publication with your loved ones on social networks, this will help the development of our project.
The order of work performed to replace the brake hose.
The braking system plays an important role in the operation of any vehicle. If at least one of its elements is faulty, then this can lead to disastrous consequences. Therefore, one should be especially vigilant to monitor the health of all elements of this system.
An important component of any braking system is the brake hose. Cracking and wear on brake rubber hoses is a common problem, and should be lubricated with silicone grease and checked periodically to prevent this. If there is any suspicion of a defect, you should immediately replace the brake hose, because its malfunction in the future can have a detrimental effect on road users.
Sequencing:
1. First of all, the vehicle should be prepared to perform the necessary operations. To do this, place it on a flat surface, install stops under the wheels on the side opposite to the suspended wheel.
For safety reasons, we install stops under the wheels.
2. Use a jack to raise the front of the machine. Place the car on the "blocks" for better stability. Remove the wheel using a wheel wrench.
To access the brake hose, lift the car.
3. Treat all replaceable fasteners and bolts of the brake system with a special penetrating lubricant. This will ensure that they are easily loosened. This work must be done in advance so that the grease penetrates deeper into the joints.
We will take care in advance by covering the threaded joints with this solution.
4. Using pliers, remove the retaining bracket from the body bracket brake hose. Holding it with a wrench 17 (so that the tip of the brake hose does not move), unscrew the brake pipe union using a wrench 10.
Using pliers, remove the bracket that secures the hose to the body.
5. Pull the brake hose out of the bracket. Make sure the brake pipe has a protective cap from the bleed nipple. If not, then brake fluid leakage is inevitable. Using a wrench 10, unscrew the fixing bolt of the bracket holding the brake hose and remove it.
Prevent brake fluid from escaping from the disconnected hose. Install the rubber cap from the bleed nipple.
6. Use wrench 14 to loosen the brake hose mounting bolt and remove it.
We unscrew the bolt that secures the hose using a 14 wrench.
7. Installing a new hose should be done upside-down. It is also necessary to replace the copper sealing washers. Having installed a new brake hose, you need to bleed the brake system.
Bleeding brake systems:
1. To bleed the brake system, fill the brake fluid reservoir to the max level.
Top up the tank on the master brake cylinder with brake fluid.
2. Next, remove the protective cap from the fitting and put a transparent hose on it, and then lower it into the container where the brake fluid is located.This prevents air from entering the brake system.
It is imperative that after replacing the brake hose, bleed the system by removing the air.
3. To bleed the brakes, you cannot do without an assistant. He must press and hold the brake pedal. Ask an assistant to press the brake pedal all the way 3 times. In this case, you must unscrew the bleed fitting using the key 10.
We unscrew the bleed fitting with a key.
Trapped air will collect in the liquid barrel. After that, you need to tighten the union by repeating the operation again. You need to repeat until the air leaves the system. 4. As the air escapes, you will need to top up the brake fluid reservoir. Upon completion of this operation, screw the bleed fitting tightly, dismantle the tube, install the protective cap, and then install the wheel in its original place. For bleeding, you need to top up with a liquid of the brand that is used in your automotive system.
As you can see, replacing the brake hose is no big deal. But this work also requires a serious and responsible attitude. Indeed, not only your life, but also those around you, depends on the quality of its implementation. In the course of performing the work, you need to use attentiveness and caution. But personal qualities will not be enough - you also need to have certain skills. If you are unsure of your abilities, then contact the service station for help.
Anything can wait on the road ...
History with broken brake hose happened about 10 days ago.
I decided to go for a drive around the city at night because of the good weather, the drivers were playful, they chased, I also joined. Passing the tram tracks to the intersection of Engels and Svetlanovsky, the pedal went to the floor and in order not to moor into the cars standing at the traffic lights, I had to fly the intersection to the red one in the opposite lane 🙂 After which it successfully slowed down, not resorting to grinding the curb with discs.
When one circuit does not work, the ABS automatically stops working and, with sharp braking, the car turns)
It happens that during the operation of the car, for various reasons, it is required replacement of brake pipes. Sometimes the repair and replacement of these parts should be carried out not even because of a breakdown, but for preventive purposes. Why this happens and how to independently repair the brake line, we will try to explain in detail just below.
The pipes and hoses of the brake system are used to transmit the force that flows with the help of the fluid from the pedal to the master cylinder, and then to the workers, which are mounted on the supporting discs. Tubes are connected to cylinders and distribution units using cone couplings.
It should be noted that it is quite possible to conduct an external examination of the state of the brake system on your own, however, in the event of any malfunction, it is better to seek help from a specialized center, where diagnostics and qualified repair of the car system are carried out, as well as fluid replacement.
According to the manufacturers' recommendations, the performance check of all vehicle components should be carried out in accordance with the routine maintenance schedule. The brake system is diagnosed once every 2 years (or every 50,000 km). Rubberized hoses must be replaced after 125,000 km, regardless of their technical condition.
The main malfunctions of the brake system:
a significant increase in the braking distance of the vehicle;
when you press the pedal, a pulsation appears and a squeak is heard;
large free travel of the brake pedal;
fluid leak;
overheating of brake drums;
when you press the pedal, the car starts to move to the side;
cracking brake hoses;
uneven pad wear.
How to repair a damaged line yourself? Repairing brake pipes requires a certain amount of experience from the driver and the ability to use locksmith tools. But not everything is so complicated. The following is a step-by-step description of the process of restoring the damaged system.
First you need to unscrew the tube from the brake cylinder or caliper.
With the help of a pipe cutter, the pipeline is cut in the right place.
The damaged area is removed.
The edge of the tube is degreased with gasoline.
Clamp the tube with pliers so that its edge protrudes by about 50 mm.
With the help of a drill inside the tube, a chamfer is removed at the edge.
At the end, you need to remove the remnants of the shavings.
Next, a fitting is pushed onto the tube.
The end of the tube is inserted into a special device and expanded.
The repaired pipeline is purged with compressed air and connected to the pipeline using a special adapter. Now all that remains is to bleed the brake system, and the car is ready for further operation.
