4 Adjustments
Adjusting the Disc Brake
WARNING!
• Disc brakes are sharp, keep fingers away from the brake
caliper and rotor. If fingers contact the disc brake while the
wheel is turning serious injury may occur.
Important! Different types of disc brakes may require specific
adjustments not covered in this section. If you are unsure of
what needs to be done see a qualified bicycle mechanic.
Misalignment of the disc brake may be due to the following:
• The wheel is not centered.
• The caliper body is misaligned.
• The brake pads are not centered.
Center the Wheel
❶ Rotate the wheel and look at the gap between the rim and
fork. If the gap is uneven, loosen the axle nuts and adjust
until the wheel and disc rotor are centered. Figure 4.16

Realign the Caliper Body
❶ Using a 5 mm Allen wrench, loosen the two centering
adjustment screws. Adjust the caliper body until the gap
between the disc rotor and the brake pads in the caliper body
is even (1/32" per side). Figure 4.17
❷ Tighten the centering adjustment screws.
