Review on ACDelco 18M364 Professional Cylinder Assembly by Kevin Williams

Packaged much better than other brands. Went right after pumping the bank, never had to pump the lines. Firestone who reported my master cylinder was frustrated that they couldn't get the job done and the previous master cylinder was not an ACDelco and there was a leak around the tank from day one of installation. This ACDelco stays as clean as if my truck were new.
