[I] hi on #1 not sure if this is the correct response i have a 92 lx auto. the tranny has a pc in it that makes the clicking noise usually 2 clicks if you are coming to a stop a hill holder feature.. the 90 91 dont have this feature.. usually hear it if you are coming to a stop.. just 2 clicks..in the front wheel area.. hear it on both sides..dont remember what the part is called. its not part of the brakes..its an auto tranny item..
