Brake problem in Opel Astra G of the year99

Hi Foros, I would need to know if someone could help my problem. The car is stopped again and again, consult with a mechanic and told me that when it happened to me that if I could have a potharm of the tweezers or rear drums and if it comes out with pressure it is for impurities in the hoses or the pump or the brake compensator.
Calce the car and disassemble the wheel, and try to remove the pills and the embolo there was no way to shrink it, after removing plug of the brake fluid deposit, remove the input corner into the gall of the clamp and that was when I could shrink it.
Please I don't know what it can be and for the prices of what the mechanic tells me a paston comes out. Both the pump the compensator and the hose, I bought the pills and have come out for 55 Eurazoas and with a good discount.
Thank you I hope you are answers

It is important that you mention which of the 4 brakes is the one that sticks, since you have front pills and tamboer tracero.

hello.
To detect the wheel that has problems after time running the pneumatic and tire takes temperature more than normal.
luck

In the beginning I thought about the rear and when the front I saw the pills with a strange color, as if they had been placed in the living red, they were toast.
Thanks for sponnder, but I do not get to that level when determining that of the temperature and I do not have so much idea, just the need to not be able to take the car to a workshop. I try to save everything possible.

hello.
Look you know what I can tell you is that first, the brake failure may be punctual and in a wheel, so with respect to the temperature I mention of the wheels, if you touch them all you should notice the defernecia between which it has problems. And with respect to the saving of repair, you cannot think about repairing it yourself, think that in the brakes your safety is and that of yours and more is, the cheap costs expensive. With the brakes it is not played. Okay.
Good luck and think about it ...
