FRONT WHEEUSUSPENSION/STEERING
SERVICE INFORMATION
GENERAL
Keep grease off the brake pads and disc.
A contaminated brake disc or pad reduces slopping power. Discard contaminated pads and clean a contaminated disc with a
high quality brake degreasing agent.
When servicing the front wheel, fork or steering slem, support the motorcycle using a safety stand or hoist.
After front wheel installation. check the brake operation by applying the brake lever.
For the brake system information (page 16-4),
When using the lock nut wrench , use a 20·inches long deflecting beam type torque wrench . The lock nut wrench increases the
torque wrench's leverage , so the torque wrench reading will be less than the torque actually applied to the fori< damper. The
specification given on this page is acluallorque applied to the fork damper, not the reading on the torque wrench when used
with the lock nut wrench . The procedure later in the text gives the actual and indicaled torque.
After the front wheel installation , check the brake operation by applying the brake lever.
