WARNING:
Overuse or incorrect use of a front-wheel brake can cause the rear wheel to lift off the ground, resulting in decreased
control of the bike or even flipping the bike and rider in the forward direction; this can lead to serious injury and bicycle
damage. Be careful when applying the front brake, and avoid using it without also using the rear brake. Ideally, both
brakes should be applied at the same time, with the rider moving rearward on the bicycle depending on the amount of
braking pressure applied.

WARNING:
Brake pads remove rim material when you apply the brake. If the brakes remove too
much material over time, the rim can become weak and break, decrease your
control, and cause you to fall. Regularly check your rims. Replace a rim that is
worn.
Rim wear indicator: shallow groove in brake track on aluminum rim.
3.6.2 Brake Adjustment
Disc brakes
When the wheel is out of the frame, do not operate the brake lever. With some
brakes, the pads automatically adjust their clearance such that you will not be able
to re-insert the disc.
Aligning a mechanical disc brake
1. Loosen or tighten the barrel-adjuster at the lever-end of the brake cable. This will
make a small adjustment to the clearance of the brake pads. If this is insufficient to
create the right clearance.
2. Loosen the two alignment bolts but do not remove them. Slowly rotate the wheel
and check the space between rotor and brake pads; adjust the position of the brake
pads so that the rotor is not rubbing and is slightly closer to the outer pad (the
clearance between rotor and pad should be just enough to prevent rubbing). Make
sure the rotor and pads are parallel to each other. Tighten the bolts when the
adjustment is finished.
3. If the rotor is always rubbing against the brake pads or if there is too much
space, you can adjust the brake pad clearance by loosening the cable-clamp bolt
and releasing the cable slightly to increase clearance or tightening the cable to
decrease clearance, then tightening the bolt again.
Note: Ensure that the brake cables are properly inserted into the brake levers
before adjusting the brakes.
