I have a few questions about the NOS Master Brake Cylinders. Is it advisable to buy them? I mean they have been sitting around for about 20 years, wouldn't the seals have dried out? The bore be pitted by mositure? I don't know how they were pakaged, if they had any type of protective lubricant applied to them, etc. Would it be better to buy the aftermarket type from one of the Delorean Dealers? I heard that the Newer type ones do not come with the switch, how true is this? Also does anyone know the make and the part number of the aftermarket type Master Brake cyinders that will work in the Delorean without having to change the calipers to match it? Thanks in advance.
