PREVENTATIVE MAINTENANCE
c.
Check the friction plate and brake disc wear condition. When any of the friction
plates is worn down to the marking line of 3mm or 3.5mm, it must be replaced in
pairs. The disc brake thickness and wear limits may differ slightly from eTrike
model to model.
d.
If the left brake handle is spongy or has little resistance or effectiveness when
squeezed, exhaust the left brake system as follows:
• Remove the main cylinder cover and add brake fluid/oil until the fluid level
reaches the upper score line. Close the cover to prevent debris from entering
• Use a hose with one end connected to the caliper oil drain screw and the other
end to an appropriate container.
• Quickly squeeze and release the left hand brake a few times, and then hold the
hand brake in place on the last squeeze.
• While the hand brake is being held in place, loosen the air release screw by
turning it counterclockwise one quarter inch. This will allow any foamed brake
fluid/oil to be released through the hose and into the container.
• Tighten the air release screw.
• Repeat steps 3 through 5 until all of the foaming brake fluid/oil is emptied and
the brake handle is no longer spongy and has proper resistance and
effectiveness.
• Tighten the drain screw and disconnect the drain pipe.
• Add brake fluid/oil to the main cylinder until it reaches the upper score line.
• Close the cover.
NOTE: Clean any spilled brake fluid/oil immediately as it can corrode painted surfaces,
plastic, rubber parts, etc. Brake fluid/oil should always remain visible in the viewing
window of the reservoir during the exhausting process. To insure this, add brake fluid/oil
to the main cylinder at any time during the process.
III. SHOCK ABSORBERS
a.
Rear shock absorbers – Inspect the rear shock absorbers after every 125 miles of
use. Replace the shock absorbers immediately if looseness or cracks are found.
b.
Front shock absorbers – Inspect the front shock absorbers regularly. Replace the
shock absorbers immediately if damage or failure is found. Note: The front fork
should be kept clean to insure proper functioning of the front shock absorbers.
IV. TIRES AND WHEELS
a.
Inspect the tires for cuts, embedded objects or other conditions/damage that can
compromise the tires’ performance.
b.
Inspect the tires for proper inflation. This inspection should always be performed
while the tires are “cold” before driving the vehicle. Recommended tire pressure is
36 PSI.
