Replacement of hoses and tubes of a hydraulic path of the brake system

See the preventions provided in the section the Brake system.


1. In case of need replacements of a hydraulic tube or a hose merge liquid from hydraulic system (see the Head Uniform hydraulic system). Alternatively minimization of losses of hydraulic liquid can be provided by a perezhimaniye of flexible hoses, or a bystry blockage of the disconnected brake tubes and their unions. Prepare to assembly of the spilled liquid, having enclosed polyethylene or rags under the corresponding nipple connection(s).
2. In need of a detachment of a flexible brake hose, give a nut of its nipple connection with a rigid tube before removing a spring collar of fastening of a hose on the arm.
3. It is the best of all to give cap nuts of nipple connections by means of a special cap key with a cutting head (ask in shops of automobile accessories). In the absence of near at hand special key it is possible to use Rozhkov who is densely sitting down on nut vents a key, however in case of strongly tightened nut such way is connected with risk of a rounding off of corners of shlits of a nut as a result of failures of a key. In that case it is necessary to try to give a nut with the help самоконтрящегося a reinforcing key (Swede). In case of damage of shlits of a nut it is subject to replacement assembled with the tube. Before a partition of nipple connection always carefully wipe it outside in order to avoid hit in system of dirt. When undocking more than one connection try to remember an order of installation of the removed sections precisely.
4. Replaceable brake tubes of various length with the razvaltsovanny ends and the put-on cap nuts can be got in service centers of the Citroyon company. Having picked up section of the required length (the corresponding removed) it is necessary only to give it the necessary form for the correct installation on the car. Alternatively, brake tubes can be made to order in a workshop of car service of the details released by sets. It is necessary to measure only precisely length of the original removed from the car. It will be most correct to take the old call with himself in shop or a workshop.
5. At installation do not tighten nipple nuts too hardly! Tightness of connection is not proportional to effort of tightening of its components at all, and is defined by correctness of their assembly.

6. When replacing flexible brake hoses pay attention to admissibility of use them in contact with hydraulic LHM liquid. Track correctness of laying of lines, do not allow twisting of hoses and you watch that they were fixed in all provided arms and clamps.

7. Having finished installation of components, add necessary amount of liquid of the required grade (address the Head Routine maintenance) in the tank of hydraulic system and pump over a path (see Pumping of hydraulic system). Wash away traces of the spilled brake fluid and check system for existence of signs of leaks.
