Dear sirs
I've the following issue: after some kilometers of road, especially if I brake hardly rear wheels remain blocked and the unique way to move the car is to purge the oil from one of the rear caliper, because they remain closed and the friction increase the temperature and causes the bloccage.
I replaced component in the calipers (gasket, cilinders and so on) but the issues stay there...I baught a new brake pump but the actual seems equally new, so my mechanic told me that the problem should be in the "distributor" of rear brakes (I attache the pictures, I don't know the true name of this component). So I don't know where I can buy a new one because in Germany (https://www.simon-auto-shop.de/About-us ... Simon-Auto) doesn't have it. So I'm asking you a suggestion where I can buy it or if it is possible to fix the problem or if you know different causes. Thanks in advance.
