MAGURA Julie
On the fully hydraulic MAGURA disc brake systems Julie and Clara the braking force
is transmitted 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 caliper, where two pistons, on which the brake pads are fixed, are pushed out.
The friction between the brake pads and the rotor is slowing down the bicycle and cau-
ses a heating of both the rotor and the brake caliper.
Never touch either the rotor or the brake caliper after long braking as this
may cause serious burns.
You will be pleased to find out that the MAGURA Clara and Julie 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 shortly after activating
the brake lever.
Disc brakes do not cause a wear of your rims. In case of insufficient mounting conditi-
ons they might however cause a squealing noise during braking, mainly in wet weather
conditions.
This manual contains important information about the safe installation, ope-
ration 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.
All steps will be explained on the Julie model. Any differences with the
Clara model will be clearly mentioned.
although the Clara and Julie disc brake systems are relatively simple you
should not overestimate your technical skills! We therefore advise you to leave
the following works to a trained technician of a professional bike shop.
