well i recently purchased a used master cylinder and brake booster from this guy, i installed the m/c and booster in my car and it worked fine for a coulpe of days, but after a day or two i seen that it was leaking where the m/c connects to the booster( the booster's paint was peeling due to the spillage from the fluid, so for sure it was leaking) thats the same place where it leaked before, did i get another faulty m/c or is there something else wrong, thanks

 

nope, the master is bad. buy a new one, all the used ones die like that, its common
