WARNING! Danger of accidents
Reduced braking ef ciency can be caused
by worn brake pads.
– Check the brake pads regularly.
– Change worn brake pads immediately.
NOTE: If the brake pads are
not changed in time, the steel
brake pads carriers grind on the
brake disc. The braking effect is greatly
reduced and the brake discs are rendered
unserviceable.
Brake Inspection
Brake Pads
1. Visually inspect the brake pads
A
for wear,
cracking, and damage on all brake calipers.
2. Ensure they have the minimum thickness.
Minimum thickness 1 mm
(≥ 0.04 in)
If the minimum thickness is less than
speci ed or damage is found, change the
brake pads.
Brake Discs
1. Check the thickness of the brake disc in several
places to see if it is within the speci ed wear
tolerance.
Wear Limit
Front ≥ 4.5 mm (≥ 0.18 in)
Rear ≥ 4 mm (≥ 0.16 in)
If the brake disc thickness is less than the
speci ed value, change the brake discs.
Brake Lines and Master Cylinders
1. Visually inspect the brake lines and master
cylinders for leaking and cracking. Replace
components if necessary.
Brake Fluid Level
Checking/Adding Front Brake Fluid Level
1. Remove the brake uid reservoir mounting
screw
B
.
2. Check that the uid level is between the MIN
and MAX markings. Add Motorex Racing brake
uid to the MAX level.
3. Remount the brake uid reservoir.
Checking/Adding Rear Brake Fluid Level
1. Position the motorcycle on rear lift stand.
2. Check that the uid level is between the MIN
and MAX markings. Add Motorex Racing brake
uid to the MAX level.

Brake Bleeding
Bleeding Front Brake Calipers
Use standard manual or vacuum bleeding
procedures to bleed the front brake calipers.
SPECIAL NOTES:
• Bleed each caliper individually using the
bleed screw
C
.
• Bleed brake lever at the bleed screw
D
.
Bleeding Rear Brake Caliper
Use standard manual or vacuum bleeding
procedures to bleed the brake caliper.
SPECIAL NOTES:
• Remove the rear brake caliper and invert
with the bleed screw
E
facing up.
• Raise the caliper to a position where the
bleed screw is higher than the master
cylinder.
• Place a 6 mm Allen wrench between brake
pads to simulate the brake disc.
• Bleed the caliper using standard procedure.
• Remove the Allen wrench and install the
caliper back on the motorcycle.
