Adjust the "free travel" of the brake pedal to 1/4 inch, by turning the 19mm "Piston Push Rod" on the thrust rod of the brake booster.

To increase free play at the pedal - decrease the number of visible shaft threads then tighten the 19mm Thrust Rod Lock Nut.

I installed a new master and power booster. Bled the prakes. Brakes work perfect. All air no spongy feel. Brakes work. I adjusted the park brake and rear brakes.

My problem: brake pedal too low. Is the height adjusted with part 26a control rod? 1973 GT
