Suzuki DR650SE - Brake Pad Replacement; Brake Fluid Replacement and Bleeding

2-11 PERIODIC MAINTENANCE
BRAKE PADS
The
extent of brake pad wear can be checked by observing
the grooved limit line G) on the pad. When the wear exceeds
the grooved limit line, replace the pads with new ones. (Refer
to pages 5-7 and 5-34.)
I A CAUTION I
Replace the brake pad as a set, otherwise braking per-
formance will be adversely affected.
BRAKE PEDAL HEIGHT
•
Loosen the lock nut @ and rotate the push rod @ to lo-
cate brake pedal 5 mm below the top face of the footrest.
• Retighten the lock nut @ to secure the push rod @ in the
proper position.
Brake pedal height @: 5 mm (0.2 in)
AIR BLEEDING THE BRAKE FLUID CIRCUIT
Air trapped in the fluid circuit acts like a cushion to absorb
a
large proportion of the pressure developed by the master
cylinder and thus interferes with the full braking performance
of the brake caliper. The presence of air is indicated by
"sponginess" of the brake lever and also by lack of brak-
ing force. Considering
the danger to which such trapped air
exposes
the machine and rider, it is essential that, after re-
mounting the brake and restoring the brake system to the
normal condition, the brake fluid circuit be purged of air in
the following manner:
• Fill up the master cylinder reservoir to the "UPPER" line.
Replace
the reservoir cap to prevent entry of dirt.
• Attach a pipe to the caliper bleeder valve, and insert the
free end of the pipe into a receptacle.
