Buick Special (1965); Buick, All (1966-73)

Adjustment is necessary whenever rear brake cables have been disconnected. Adjustment is also required if service brakes operate properly, but parking brake depresses more than eight ratchet clicks on Century and Regal models, or more than 16 ratchet clicks on all other models. To adjust, depress parking brake exactly three ratchet clicks, loosen jam nut at rear of equalizer adjusting nut, and tighten adjusting nut until rear wheels can just be turned rearward (using two hands), but will lock when turned forward. Tighten jam nut against adjusting nut. With mechanism totally disengaged, rear wheels should turn freely in either direction.
