IDEAL Bikes Trekking Series Original Instruction Manual page 36

Opening the cantilever or V-type brake
• Grip around the wheel with one hand.
• Press the brake arms together and against the
rim
• Detach the brake cable or the outside of the
cable duct at one of the brake arms
Side-pull caliper brake
Opening the side-pull caliper brake:
• Open the quick release lever on the brake arm
or lever, or:
• If you do not have a brake quick release, deflate
all of the air out of the tyre. Now the wheel can
be pulled out from between the brake pads.
Brake pad wear
The brake pads for rim brakes are almost all fitted
with grooves or notches.
The grooves and notches serve in part to help
identify the wear level of the brake pads. If these
can no longer be seen, you should replace the
brake pad.

Hydraulic rim brake
Removing the hydraulic rim brake:
• If your system features a brake quick release,
remove the brake unit according to the instruc-
tions supplied by your manufacturer.
• If you do not have a brake quick release, de-
flate all of the air out of the tyre
Mechanical oder hydraulic disc brakes
Disc brakes
• The wheel can be removed without any further
preparation.
• Please note: when fitting the wheel, the disk
must be slotted between the brake linings of
the brake caliper and ultimately be centred
without contact.
Vapour bubbles in the disc brakes
Avoid permanently braking for long
periods, as can be the case during
long, steep descents. The forma-
tion of steam bubbles and total failure of the
brake system might otherwise result. This may
cause severe falls and injuries.
The brake lever may not be activated when
the bicycle is lying on its side or turned up-
side down. Otherwise air bubbles can enter
the hydraulic system which could cause the
brakes to fail. Test after each journey wheth-
er the pressure point of the brake feels softer
than it did before. Slowly activate the brake
several times. This allows the braking system
to discharge any bubbles. You may not ride
on when the pressure point remains soft. A
specialist retailer has to discharge the air from
the brake system.
You can avoid this problem by apply-
ing the brake lever before transport
and then fixing it in this position using
a strap. This prevents any air from entering
the hydraulic system.
