Brake problem in Opel Astra G of the year99

Thank you partners to all, first of all, but in no case I have said that I knew a lot about mechanics, only basic notions and what I look for and inform myself.
In no case have I tried to anger anyone or anything similar, apologies in case I have offended any professional in the sector, I only intended to save me for a few euros and keep learning something else.
Thanks for your answers and comments.
Forgive for having created a dispute does not hera my intention, much less

Hello friends I am new here but I would like to contribute something. First the exchange of ideas knowledge and experiences is the basis of forums within always of a frame of respect and without fighting I believe. Now about the problem of our friend I must say that the problem is in the brake pump because the valves that allow the return of the liquid to the pump once the pedal was stopped for some reason are not acting well this goes through impurities in the liquid, due to decomposition of the same or on some occasions because the appropriate liquid is not used. Guide the brakes are something delicate and they should not be repaired without having the appropriate knowledge I hope that solutions your problem I say goodbye to me

It seems to me that everyone is right, in what I do not agree is in which Gonzo and his srvidor are fighting, "no" we are fighting, we are only giving our views, this helps the forum since I enrich it of ideas and opinions, not all ideas will be related open ideas opposite but this is normal. What I want to contribute in this forum is based on my experiences, problems and solutions that I have had to face with the cars that I have had, for example I have a Nissan Quest 96 I make all its liquid changes every 5000 km. (Brake fluid, oil, hydraulic direction and two months ago I changed the liquid of the automatic transmission with everything and filter) change the eight tiles and purge brakes, change of brake cylinders if they have a leak, change of bands, water pump, distribution band, thermostat, only this I mention is preventive maintenance that is revealed to all the vehicle etc.etc.etc. What I need is done to do so, do you know how much I have saved me? And the most important thing do you know how I learned about? Do not study mechanics ... Well, encouraging me to get hand, investigating in these forums, asking, observing and that is the advice that humbly leaves you, anime and put hand, but when are we going to learn? And incidentally, a lanota, money, euros, in my case Mexican pesos ... and Gonzo sorry for me if I offend you, it only remains for me to watel some chelas here in Mexico, Toluca.

Gentlemen obstructed from the leds Delanreras more than 70% of the cases is therefore obstructed by impurities and the brake fluid passes but does not return and the kaliper piston does not return and of course the car is slowed down.-
