Well, after an interesting drive up 93N thru Boston at 4;30 pm last Saturday where my brakes totally went south , I need to replace or rebuild the master cyliner in my 54 Buick Special. My questions are...Is there an advisable, relativly simple upgrade solution? Or does any one have a suggestion wher I can find a re-built or NOS origonal. I'm not seeing anything other than re-build kits on Scarebird and the other obvious sources. I'f I can't upgrade I'd rather bolt on than re-build. Thanks.
