5. Disc brakes can get extremely hot with extended use. Be careful
not to touch a disc brake until it has had plenty of time to cool.
6. See the brake manufacturer's instructions for operation and
care of your brakes, and for when brake pads must be replaced. If
you do not have the manufacturer's instructions, see your dealer
or contact the brake manufacturer.
7. If replacing worn or damaged parts, use only manufacturer-
approved genuine replacement parts.
It's very important to your safety that you learn and remember which brake
lever controls which brake on your bike. Traditionally, the right brake lever
controls the rear brake and the left brake lever controls the front brake; but,
to make sure your bike's brakes are set up this way, squeeze one brake lever
and look to see which brake, front or rear, engages. Now do the same with
the other brake lever.
Make sure that your hands can reach and squeeze the brake levers
comfortably. If your hands are too small to operate the levers comfortably, consult
your dealer before riding the bike. The lever reach may be adjustable; or you may
need a different brake lever design.
Most rim brakes have some form of quick-release mechanism to allow the brake
pads to clear the tire when a wheel is removed or reinstalled. When the brake quick
release is in the open position, the brakes are inoperative. Ask your dealer to make
sure that you understand the way the brake quick release works on your bike (see
figs. 12, 13. 14 & 15) and check each time to make sure both brakes work correctly
before you get on the bike.
The braking action of a bicycle is a function of the friction between the
braking surfaces. To make sure that you have maximum friction available, keep
your wheel rims and brake pads or the disk rotor and caliper clean and free of
dirt, lubricants, waxes or polishes.
When you apply one or both brakes, the bike begins to slow, but your
body wants to continue at the speed at which it was going. This causes a
transfer of weight to the front wheel (or, under heavy braking, around the
front wheel hub, which could send you flying over the handlebars).
A wheel with more weight on it will accept greater brake pressure before
lockup; a wheel with less weight will lock up with less brake pressure. So, as you
apply brakes and your weight is transferred forward, you need to shift your body
toward the rear of the bike, to transfer weight back on to the rear wheel; and at
the same time, you need to both decrease rear braking and increase front braking
force. This is even more important on descents, because descents shift weight
forward.
Two keys to effective speed control and safe stopping are controlling wheel
lockup and weight transfer. This weight transfer is even more pronounced if
your bike has a front suspension fork. Front suspension "dips" under braking,
increasing the weight transfer (see also Section 4.F). Practice braking and weight
