1. Welcome to the Passion People!
On the fully hydraulic MAGURA disc brake system Julie HP the braking force is transmit-
ted to the braking surface by a mineral oil column. The movement of the lever blade moves
a piston, which is integrated in the brake lever (master cylinder). The piston pushes the
mineral oil column through the brake hose in the direction of the brake calliper, where two
pistons, on which the brake pads are fixed, are pushed out. The friction between the brake
pads and the rotor slows down the bicycle and causes both the rotor and the brake calliper
to heat up.
Never touch either the rotor or the brake calliper after long braking as this may
cause serious burns.
You will be pleased to find out that the MAGURA Julie HP disc brakes offer a superior
braking power even with little hand force applied, no matter what the weather conditions
should be. Particularly in wet weather conditions disc brakes are much more responsive
than rim brakes and transmit their enormous power immediately after activating the brake
lever.
Disc brakes dont’t wear your rims down. However, if they have been mounted incorrectly,
they might cause a squealing noise during braking, mainly during wet weather conditions.
This manual contains important information about the safe installation,
operation and maintenance of your MAGURA disc brake. We urge you to read
it carefully, become familiar with its contents and follow our recommendations to
help make your new braking experience enjoyable and trouble free. Please note that
the Louise brake is delivered in different versions with different rotor diameters and
for different fitting alternatives for which we offer a variety of adaptors. The basic
installations steps remain however always the same.
Although the Julie HP disc brake system is relatively simple you should not over-
estimate your technical skills! We therefore advise you to leave the following operati-
ons to a trained technician of a professional bike shop.
