Check Peugeot 106xr

Greetings:
I need information about the Peugeot 106xr Nesecitos brake systems know where I can find an image or specific model name of the rear brake pumps, I would like to know how much they are worth approximately and some images of these.
Thank you very much for your help. Bendeitions

I would also like to know if there is some other brake pump for the rear of some other brand that served the Peuxot since in my country I cannot find the original pumps for the car.
thank you.

Friend for me that I have understood, or at least the Peugeot 106 that I have harregated here in Chile, they only have a brake pump for the 4 wheels, unless you call it a bomb elsewhere, we call the element that is ahead of the servofreno, in any case these pumps can be repaired and the interior rubbers can be repaired.

Thank you very much for your answer, the one you mention is the central brake pump that you feed 4 wheels, apparently with what I have problem is in the rear wheels, there are 2 "pumps" that move the jaws of the brakes are 19 mm the inner piston and those are the ones that were ruined to me which I do not find the originals in my country do not sell me or the packaging To repair these.
Thank you very much for your answer and I wish you many blessings

Ok now I understand what you are looking for are the cylinders of the rear brakes, which move the balatas, hahajaj Mira also have repair, the same prosecuted as Renault or Citroen, are the same in many cases their components, luck and let me know anything, as I tell you the brakes can be adapted but you have to do it very well, so as not to take risks.
