6 Use needle nose pliers to install the SwingLink™ bushings into the
lever SwingLink pivot holes so that the lip of the bushing is flush on the
inside of the lever body.
If the SwingLink bushings fall out easily, apply a small amount of
grease to the bushings to help hold them in place.
7 Use a caliper to verify that the push rod lenth in the SwingLink™ is
26.3 mm. Turn the push rod counter-clockwise by hand to extend the
pushrod length. Turn the push rod clockwise by hand to decrease the
pushrod length.
The push rod length must be set to exactly 26.3 mm. Any other length
will reduce brake performance.
8 Place the SwingLink onto a 2 mm hex wrench then insert the pushrod
into the coupler sleeve.
