last week when i opened up my distributor and took it to my mechanic for O ring change, whose workshop happens to be near my home he was telling if you messed up with this thing will cost you 4000-5000 to replace it , from that i think 3500 seems to be on high side, he replaced that round fork sorta thing on end of rotor shaft? what was final tightness of it over the shaft, was there some free play in it after putting in the lock pin or it was snug fit?
if the pads were black looking it was metal, the non metalic leather type are just same as rear brake leather, and let pads settle and they will end stinking and when they wear off to the stage where they can find room to rattle, sure they will will check wit my mechanic about the shims and let you know.
