Brake System Inspection - E-TON Beamer R4 Owner's Manual

The rear brake is the primary stopping brake on your
vehicle. Using the rear brake to stop your vehicle will
prevent steering control loss.
Use your front and rear brakes in combination to
control your speed while descending a grade. Use
caution not to apply too much pressure to your front
brake so that the wheels lock up, stop turning, and
cause a loss of steering control. If the front wheels lock
up, stop turning, lightly reduce the pressure on the
front brake lever until it unlocks and the wheel start to
turn.

Visually inspect the brake lines for any signs of wear.
Inspect the lines for leaks at all connections and look
for wear along the entire line. Replace the line if any
worn areas are found. The brake is under great
pressure when the brakes are applied and any worn
spot could cause a rupture of the line.
Inspect the brake arm, spring, rod and fastener for
signs of wear or damage. Operate the brake lever
while watching the brake mechanism for proper
operation. Tighten, repair or replaces parts as needed
to insure safe and proper operation of the brake
system. Clean any build‐up of mud or debris from the
brake mechanism.
The brakes are equipped with a wear indicator to alert
you when your brake pads need replacing. Apply light
pressure to the brake lever and slowly push the unit
forward. If you hear a high pitched metallic scraping
sound, you need to replace your brake pads. The
minimum pad thickness is 3.0mm.
DO NOT RIDE A VEHICLE WITH WORN BRAKE PADS.
Check the rotor disc for cracks, warping or color
distortion. Replace rotor disc at first sign of problem.
Check rotor disc thickness. Minimum thickness is
3.1mm. Replace the disc if below minimum thickness.
Check the fluid level in the fluid reservoir by checking
the site glass for the level.
The fluid level should fill at least
the unit is setting on a level surface.
Test the brakes by applying pressure to the brake lever
and trying to push the unit forward. If the wheel
rotates while the brakes are applied, check your fluid
level and brake pads. If the brake lever feels spongy or
does not stop when squeezed, you may have air in the
lines. All air must be purged from the brake lines for
the disc brake to operate properly. (See purging brake
lines).
