Pulling to Right when braking

[dizzyfingers]

I have a 1981 4x4 Blazer. Problem is when I brake the vehicle pulls sharply to the right. So far have changed both front rotors, discs and calipers. Front end has been aligned and checked by local shop. 2x Both back brakes have been redone, including shoes, drums and pistons. Power steering box was a little loose so it was changed also....not much else left...right ???? It still pulls sharply when the brakes are applied.....my only other guess might be a bad flex hose on the drivers side....need a fix quick...i'm running out of parts...haha
anybody else expereince this unsolved mystery ??
thanks....wpm
