Car pulls to left when braking

Where there is a cable operated adjust paw, the cable guide has a short neck on the backside to locate it centered in its location. If that cable guide isn't proper you could have only one adjuster operating properly.
I know of one case where a guy put one side togeter wrong and the father he went the worse the brakes became.
Then there was another car that suddenly started pulling left when braking and I found the outer half of the strut rod bushing had fell off. That will give a clunk noise with the hard jerk to one side. Good luck
