Though exhilarating to drive a car with non-functioning brakes, I decided to spring for the Mercedes 190b master cylinder rebuild kit. Some highly specific components and absolutely useless instructions add up to an annoying $50 kit. The rebuild went very well but now I have to resolve the passenger front hub in a meaningful way. I had replaced the hub and tie-rod ends but the front passenger wheel still has a nasty shimmey. I mean, in comparsion to no brakes, it is the very model of safety.
