Adjusting the brake lever reach
With disc brakes the brake levers can be adjusted to the size of your hands, too,
allowing you to operate them with optimal effectiveness (e).
For more information see the chapter “Brake lever reach adjustment on
BERGAMONT road bikes and BERGAMONT cyclo-cross bikes” and the original
manual of the brake manufacturer on this BERGAMONT info CD.
After adjusting check the functioning and make sure the brake pads do not
drag when releasing the brake lever and spinning the wheel.
DISC BRAKES
Operation and wear
The most striking feature of disc brakes (f) is their outstanding braking effect.
They respond a lot faster in wet conditions than rim brakes do and achieve their
normal high braking power within a very short time. They require little mainte-
nance and do not wear down the rims as rim brakes do. Disc brakes consist of
the brake calliper, the rotor, the brake lines (hydraulic) or cables (mechanical) as
well as the brake lever unit. Actuating the brake lever compresses the hydraulic
pistons through hydraulic pressure or mechanically, pushing the brake pads
against the rotor.
The friction generated by braking causes wear to the brake pads as well as to
the rotors. Frequent rides in the rain and dirt can accelerate wear on both brak-
ing surfaces. Depending on the manufacturer and the model there are different
ways of checking the brake pads and rotors for their wear limits.
DANGER!
G
New brake pads have to be bedded in before they reach their optimal brak-
ing performance. Accelerate your BERGAMONT bike about 30 to 50 times
to around 30 kmh and bring it to a halt each time. This procedure is finished,
when the force required at the lever for braking has stopped decreasing.
DANGER!
G
Disc brakes get hot in use. For this reason do not touch the brakes directly
after stopping, especially after a long downhill ride.
Synchronising and readjusting
Almost all brake designs have a bolt located next to one or both brake callipers
for adjusting the spring preload (a). Turn the bolt slowly and watch how the gap
changes between brake pads and rim.
Adjust the spring in a way that the gaps are equal on either side with an unap-
plied brake and the brake pads touch the rim simultaneously during braking.
The position of the brake lever where the brake starts to act, also referred to as
pressure point, can be adjusted to the size of the hand as well as to individual
convenience by readjusting the brake cable.
Make absolutely sure you cannot pull the brake lever all the way to the handle-
bar grip. With an unapplied brake the brake pads should not be too close to the
rim sides, otherwise they could drag along the rim during riding. Before making
this adjustment, observe the notes in the chapter “Brake lever reach adjustment
on BERGAMONT road bikes and BERGAMONT cyclo-cross bikes”.
With ongoing brake pad wear, the pressure point at the brake lever moves to-
wards the handlebars. Check the free travel at regular intervals; it should not be
longer than a quarter to a third of the whole travel. If necessary, readjust at the
additional brake levers on the handlebars (b). Turn the adjusting bolt anticlock-
wise.
If no additional brake levers are installed, readjust at the cable stop at the fork
or the frame (c). Release the lock nut and undo the slotted adjusting screw anti-
clockwise. If the free travel complies with your wishes, hold the adjusting screw
tight and turn the lock nut against the cable stop until you feel a resistance.
DANGER!
G
Always test the brakes’ function when stationary after adjusting them, mak-
ing sure the brake pads hit the rim evenly with the entire surface (d) without
touching the tyre when you pull them hard. Make sure you cannot pull the lever
all the way to the handlebars.
