Razor ScreamMachine Owner's And Safety Manual page 16

NOTE: The brake system requires a break-in period. You may
have to repeat procedure 6F often during the first several hours of use.
Repeat as necessary thereafter to maintain proper brake function.
The Electric Scream Machine is supplied with a brake lever that adjusts
to accommodate a variety of hand sizes. To adjust the brake lever so it
is easier for shorter hands to operate the brake, turn the screw in the
direction marked "B" in the photo below. Leave enough gap between
the handlebar and lever to assure proper brake function. To readjust for
larger hands, turn the screw in the direction marked "A" as shown in
Figure 13a below.
WARNING: Always test the brake function whenever making any
adjustment to the braking system.
WARNING: Brake pads are subject to normal wear and tear.
Although the brake pad alignment is pre-adjusted at the factory and
should not require additional adjustment at the time of assembly, it is
Figure 8c.
Figure 13a.
