Once the abrasion of one rim has reached a certain criti-
cal point, the rim may break under the tire pressure. This
can make the wheel jam or the inner tube burst. Risk of
an accident!
Keep the hydraulic brake assemblies, especially the
brake pad area, clean, as dirt can prevent the pads from
travelling back in their rest position. Check the lines and
connections from time to time for leaks.
G
Loose connections or leaky brake lines dras-
tically impair the braking effect. If you find
leaks in the brake system or buckled lines,
contact your MERIDA dealer. Risk of an accident!
Functional check
Check whether the brake blocks are perfectly aligned
with the rims
(a+b)
and are still sufficiently thick. You
can judge the wear of the brake pads by the appearance
of grooves
(c)
. If the pads are worn down to the bottom
of the grooves, it is time to replace them. Be sure to ob-
serve the according instructions of the respective man-
ufacturer.
See your MERIDA dealer and ask him to examine the
remaining thickness of the rims at the latest when you
are through your second set of brake pads. He has
special measuring devices to determine the remaining
thickness of the rims
(d)
.
The brake pads must hit the rim simultaneously and
in parallel
(e)
. This setting is to prevent the brake pads
from screeching when applied.
The brake lever must always remain clear of the han-
dlebars. You should not even be able to pull them all
the way to the handlebars in the event of an emergency
stop
(f)
. If this is the case, however, observe the follow-
ing chapter “Synchronizing and readjusting”.
Only a successful passing of all these points will ensure
a correctly adjusted brake.
G
Adjusting the position of the brake blocks
relative to the rims requires a considerable
degree of skill. Replacing and adjusting the
brake blocks is a job best left to your MERIDA dealer.
G
Have your rims regularly inspected and mea-
sured by your MERIDA dealer.
Synchronizing and readjusting
Hydraulic rim brakes are synchronized together with the
alignment of the brake pads. The position of the brake
lever where the brake starts to act, also referred to as the
pressure point, can be adjusted to the size of the hand
as well as to individual convenience at the same time.
Also observe in this regard the instructions given in the
chapter “Adjusting the brake lever reach“.
