1973 Mini with single line and metal type reservoirs from factory. Couple of years ago the original brake master cylinder was replaced by a newer plastic one, which seems to be failing so soon now.
Although more expensive, If I had to purchase another one I am temped to buy the original metal can, but I have no reference about the quality of the ones manufactured Today (if they are Chinese crap prone to failure or if they are like in the past) neither about the plastic type available at Minispares for example...
Any experiences? Is any type supposed to be better than the other one?
