NOTE: This is what special keys for pipeline fastening nuts look like.
To prevent sudden failure of the brake system, carefully check the condition of all pipelines. Replace parts with new ones if there is the slightest doubt about their suitability. All rubber parts of brake assemblies (hoses, cuffs, etc.) regardless of their condition, replace them with new ones after 100 thousand km of mileage or 5 years of operation (whichever comes first), to prevent sudden breaks due to aging.
USEFUL TIP: Brake fluid is very hygroscopic - it absorbs moisture from the air, which, in addition to causing corrosion of brake system parts, lowers the boiling point of the fluid itself, which can lead to brake failure with frequent intensive braking. Therefore, we recommend replacing the brake fluid at least once every 2 years.
Check the tightness by external inspection:
- from above, from under the hood;
- from below the car (on a lift or inspection pit);
- from the sides of the car with the wheels removed.
HELPFUL TIP: When inspecting the hydraulic drive part that works under pressure, have an assistant press the brake pedal four or five times (in order to create pressure in the hydraulic drive) and hold it down until you have inspected the hydraulic drive. Inspecting the hydraulic drive without pressure is acceptable, but less effective.
NOTES: If leaks are detected in the connections, tighten the clamps, plugs, and nuts. Replace hoses and pipelines with mechanical damage. If the working cylinders are leaky, repair or replace them.
1. Inspect the master cylinder, the connections of the pipes to the master cylinder...
2. ...and the reliability of the hose connection to the clutch release drive master cylinder, installed on the reservoir nipple (if the car is equipped with a manual transmission). If the vehicle has an automatic transmission, the nipple is plugged.
3. Inspect the connections of the pipes to the hydraulic electronic unit of the anti-lock braking system (ABS).
4. Check for fluid leaks from the connections of the brake pipes to the front...
5. ...and rear brake mechanisms.
6. Carefully inspect the brake hoses. They should not have any cracks, tears or abrasions. Press the brake pedal all the way down: if there are any bulges on the hose, the braiding threads of the hose have broken and it must be replaced.
7. Inspect the hose connections to the working cylinders and the air release valves of the front brake mechanisms...
8. ...and connections of tubes with working cylinders and valves for releasing air from the brake mechanisms of the rear wheels.
9. Check the condition of the plastic pipe holders. Replace damaged holders, as their weakening or breakage leads to vibration and, as a result, to pipe breakage.
