The braking system performs one of the most important functions - it provides a controlled change in the speed of the car, contributes to its stopping and holding in place during parking, therefore, the highest requirements are always imposed on it. The main type of drive in the service brake system is hydraulic, which, in addition to the brake pedal, booster, brake master cylinder and wheel cylinders, includes hoses and pipelines.
Necessary
- - wrench;
- - brake fluid;
- - capacity;
- - vinyl tube.
Instructions
Step 1
As a rule, the replacement of brake pipes is preceded by preparatory work associated with cleaning the surface of the connecting pipes from dirt, and applying a special compound to the threaded connections to facilitate loosening of the nuts. In addition, it is necessary to prepare in advance a special wrench, brake fluid for topping up, an empty clean container for draining the residual waste fluid from the brake system and a soft vinyl tube.
Step 2
As an example, consider replacing a brake pipe on a VAZ-2107 car. For greater convenience, place the car on an inspection pit or on an overpass. First, use a Phillips screwdriver to unscrew the two self-tapping screws holding the rear brake pipe to the car body (if any).
Step 3
After that, using a special wrench, unscrew the two fittings securing the tube to the brake hose and pressure regulator and remove the tube. At the end of all the necessary work, the pipes are installed in the reverse order, followed by adding brake fluid and checking the quality of the brake repair.
Step 4
On VAZ-2110, 2111 and 2112 cars, the first step is to unscrew the tubes from the master cylinder and brake hoses, and then plug the holes of the master cylinder and hoses. In the next step, unscrew the three retaining nuts and remove the plastic cover. Then you can already remove the metal plates and disconnect the tubes from the holders. If the holders are broken, they must be replaced.
Step 5
Install new pipes in reverse order, then bleed the brake system as a check. It is necessary to remove trapped air. A sign of air entering the brake system is an increased stroke and a soft sagging of the brake pedal when pressed. There is the following order of brake bleeding: rear right, front left, rear left and front right.
