2007 Buell Firebolt: Maintenance 1-21
HOME
BRAKE PAD THICKNESS
1WARNING1WARNING
Always replace brake pads in complete sets for correct
and safe brake operation. Improper brake operation
could result in death or serious injury. (00111a)
See Figure 1-14. Inspect brake pads for damage or excessive
wear. Replace both pads as a set if friction material of either
pad is worn to 0.040 in. (1.0 mm) or less. If this amount of
wear occurs, wear grooves will disappear from friction mate-
rial surface.
BRAKE ROTOR THICKNESS
1WARNING1WARNING
Check that no lubricant gets on tires, wheels or brakes
when changing fluid. Traction can be adversely affected,
which could result in loss of control of the motorcycle
and death or serious injury. (00047b)
See Figure 1-15. Check brake rotors for minimum thickness:
● At every scheduled service interval:
1. Inspect rotor. Replace rotor if warped or badly scored.
2. Measure rotor thickness. Replace rotor if minimum thick-
ness is less than 0.18 in. (4.5 mm).
NOTE
● See 2.12 FRONT BRAKE CALIPER or 2.15 REAR
BRAKE CALIPER for rotor replacement procedure.
● Whenever rotor is replaced, replace rotor drive bushings,
fasteners, washers and springs.
