4.3.24. Check of tightness of a hydraulic actuator of brake system

For the prevention of sudden refusal of brake system carefully check a condition of all pipelines. Replace details new if there is the slightest doubt in their suitability. All rubber details of brake knots (hoses, cuffs, etc.) irrespective of their condition replace new through 100 000 km of run or in 5 years of operation (that will come earlier) to warn sudden gaps because of aging.

Good advice
Brake liquid is very hygroscopic and absorbs moisture from air that, besides emergence of corrosion of details of brake system, lowers temperature of boiling of the liquid, and it can lead to refusal of brakes at frequent intensive braking. Therefore we recommend to replace brake liquid not less often than once in two years.

Check tightness external examination:
– from above from under a cowl;
– from below the car (on the lift or in a viewing ditch);
– from car sides with the removed wheels.

Good advice
Survey of a part of the hydraulic actuator working under pressure, see off with the assistant. It should press four-five times a brake pedal (thus to create pressure in a hydraulic actuator) and to hold it pressed until you do not examine a hydraulic actuator.
Survey of the hydraulic actuator which is not under pressure, let us assume, but is less effective.

Notes
At detection of violation of tightness of connections tighten collars, caps, nuts.
Hoses and pipelines with mechanical damages replace.
If working cylinders are not tight, repair or replace them.

1. Examine a tank of the main brake cylinder, connection of pipelines with the main brake cylinder...
2.... and connections of pipelines with the electrohydraulic block of anti-blocking system of brakes (ABS).
3. Check, whether there is no leakage of liquid from connections of brake tubes with hoses of lobbies...
4.... and back brake mechanisms.
5. Carefully examine brake hoses. Hoses should not have cracks, anguishes and attritions. Press against the stop a brake pedal: if on a hose there were swellings, means, threads of a braid of a hose tore and it is necessary to replace it.
6. Examine connections of hoses with working cylinders, remove protective caps and check on absence of leaks valves for production of air of brake mechanisms of forward wheels.
7. Examine connection of brake tubes with working cylinders, remove protective caps and check on absence of leaks valves for production of air of brake mechanisms of back wheels.
8. Check fastening of pipelines in holders on the body bottom...
9.... on a board of a motor compartment...
10.... and on longerons. Replace the damaged holders as their easing or breakage lead to vibration and, as a result, to breakage of pipelines.
