Abstract
A tandem brake booster having first and second lever arms for transferring an output force from a second wall into an output member in response to an input signal being applied to a control member. A first cam surface on each lever arm engages an annular fulcrum member and a second cam surface engages the output member. The engagement of first and second cam surfaces on the fulcrum and output member direct said output force from said second wall into said control member along a force vector substantially parallel to the output member without the introduction of rotational forces on a first wall.
