IT IS NOT IMPORTANT THAT THE SYSTEM
IS SQUARE WHEN RELEASED, BUT IT HAS

FOR MAXIMUM EFFICIENCY, IT IS
RECOMMENDED THAT THE PEDAL
IS AT RIGHT ANGLE WITH THE PUSHRODS
UNDER MAXIMUM BRAKING LOAD;
AND ALSO KEEPING THE BALANCE BAR
CENTRAL WITH BETTER SELECTION OF
MASTER CYLINDER SIZES HELPS REDUCE
INEFFICIENCIES.
ALSO MAKE SURE THAT THE MASTER-
CYLINDER PISTONS FULLY RETURN BEFORE
USE. THIS CAN BE CHECKED BY FEELING
THE PUSHRODS FOR SLIGHT MOVEMENTS
THERE SHOULD NOT BE ANY EXCESSIVE
LOOSE MOVEMENT.
MAX ANGLE ADJUSTMENT AT SETUP THIS IS
SET BY ADJUSTING THE THREAD ENGAGEMENT
OF THE ROD END BAR AND MASTER CYLINDER
PISTON.
THIS RELATES TO 8.0mm OF DIFFERENCE IN
TRAVEL OF FRONT TO REAR CYLINDERS.

PERPENDICULAR WHEN AT MAX BRAKE
