Abstract
A servo booster is provided with a tube coaxial with the booster output rod for relieving the booster housing of braking reaction forces. The housing of a tandem master cylinder has an externally threaded rear end which is threadedly engaged with internal threads formed on a reduced diameter front part of the tube. The retracted position of the primary piston of the master cylinder is determined by abutment with the booster output rod, and this can be adjusted by turning the master cylinder housing relative to the tube.
