21.4.3 Wear of brake pad
Most brake pads for rim brakes come with grooves or
notches.
New brake pad
If these grooves are worn and can no longer be seen, this
is normally a sign that the brake pad is worn.
Worn brake pad
Do not ride your bike if the brake pads are worn.
Have them replaced by a professional bike workshop
instead.

If required, you can readjust the rebound force via the
spring adjustment screw so that both brake arms move
symmetrically. Once you have done this, check that the
brake is working properly (see
➠
).
If the brake is still not working properly, or the brake
pad is so worn that it is not possible to readjust it,
have your bike checked at a professional bike work-
shop and replace the brake block.
21.5 Disc brakes
Disc brake
With this brake type, the brake discs are on the hub and
the brake calliper is on the frame or fork.
Have your disc brakes adjusted by a specialist cycle
shop. If this is done incorrectly, an accident may oc-
cur.
Once the brakes have been adjusted, always perform a
brake test by pushing the bike quickly forwards and oper-
ating the brake lever. You should only use your bike if you
can safely stop it using the brakes.
Disc brakes require a brake lead time during which the
braking force increases. Bear this in mind throughout the
entire brake lead time. The same effect also occurs after
replacing the brake block or disc.
