UNDERSLUNG MULTI<br />
RATIO PUSH TYPE.<br />
This new multi ratio push type pedal box<br />
allows the pushrod to remain straight,<br />
eliminating all side loads therefore<br />
making it very effi cient. The master<br />
cylinders connect directly to a high<br />
effi ciency balance bar.<br />
A lightweight aluminium base, and<br />
ergonomic steel and alloy pedals offer<br />
the user the ultimate control in this<br />
critical area.<br />

ADJUST THE PUSHRODS SO THAT THE BALANCE BAR<br />
IS PERPENDICULAR TO THE PUSHRODS UNDER<br />
MAXIMUM LOAD. THE SYSTEM IS THEN SQUARE.<br />
IT IS NOT IMPORTANT THAT THE SYSTEM IS SQUARE<br />
WHEN RELEASED, NUT IT HAS TO BE UNDER LOAD.<br />
FOR MAXIMUM EFFICIENCY, IT IS RECOMMENDED<br />
THAT THE PEDAL IS AT RIGHT ANGLE WITH THE PUSHRODS<br />
UNDER MAXIMUM BRAKING LOAD: AND ALSO KEEPING<br />
THE BALANCE BAR CENTRAL WITH BETTER SELECTION OF<br />
MASTER CYLINDER SIZES HELPS REDUCE INEFFICIENCIES.<br />
ALSO MAKE SURE THAT THE MASTER CYLINDER PISTONS<br />
FULLY RETURN BEFORE USE. THIS CAN BE CHECKED BY<br />
FEELING THE PUSHRODS FOR SLIGHT MOVEMENTS THERE<br />
SHOULD NOT BE ANY EXCESSIVE LOOSE MOVEMENT.<br />
