3. Mount the caliper onto the fork or the frame. Use a 5mm allen key. Tightening
torque: 6Nm/51 in.lbs.
4. Only the front brakes are available with a special caliper for the so-called
Postmount, which you find on Manitou suspension forks. MAGURA does not offer rear
brakes for the Postmount!
5. Very often frames are not well aligned to ensure a drag free mounting of the bra-
kes. You may have to use then the 0,2mm spacers, which you should install as shown
by the arrows between fitting eyelets and brake caliper. (See also the 3 caliper sketches
on page 9).
6. If you use a thru-axle hub you must use thicker 3mm spacers. These are either
available separately (code: 0720 829) or come supplied with the MAGURA Gustav M
thru-axle hub. If necessary you might have to use here as well additional 0,2mm spacers
for a clean and drag free positioning of the caliper.
7. Exception Julie rear caliper: Contrary to all other MAGURA disc brakes the
front and rear caliper of a MAGURA Julie are identical. However you must use the black
1mm spacers between fitting eyelets and caliper on a Julie rear brake. If necessary you
might have to use here as well additional 0,2mm spacers for a clean and drag free posi-
tioning of the caliper.
8. Mount the rotor with the 6 Torx T25 bolts onto the hub. Watch out for the cor-
rect rotation direction of the rotor (laser arrow). Use only new original bolts or thread
lock if you use old bolts. Tighten the bolts in a crossed pattern! Tightening torque:
4Nm/34 in.lbs.
9. Remove the transport device shortly before installing the wheel.
The transport device prevents the brake pads from being pushed out too
far by unintended lever squeeze. It is impossible then to install the wheel with
the rotor. So never throw away the transport device. Keep it and always clip it
between the brake pads when the wheel is removed.

Install the wheel by positioning the rotor between the brake pads and fixing the
wheel in the dropouts. Close the quick release of your wheel which you should mount
on the opposite side of the brake caliper and tighten it sufficiently. As to thru-axle
hubs or wheels consult the manual of the respective fork manufacturer.
Squeeze the lever blade several times (pump) to push the pads to their proper posi-
tion until the lever feel becomes very firm.
10. Correctly mounted disc brake wheel.
The rotor has to run directly under the separation line of the caliper halves (see arrow).
If ever this is not the case re-position the caliper with the 0,2mm spacers.
O.K.!
In case of a constantly dragging disc brake causing noise your frame is badly aligned.
In such a case you should contact your dealer who can care with the MAGURA Gnann-o-
mat disc optimizer for a totally even surface of the disc brake mounts. These are abso-
lutely necessary for a drag free function of your brake.
Do not worry when you hear friction between rotor and pads. A slight drag
is normal on disc brakes with automatic pad wear adjustment during the break-
in period. This drag will disappear after a while. The reason for this is that the
brake pads find their optimum working position towards the rotor, only after a
slight wear during the break-in period. Slight drag might also happen after a
brake pad change or in case of an incorrectly installed wheel.
New brakes and/or new rotors or brake pads must always be run in by
breaking at least 30 times from a speed of 30km/h to achieve the maximum
brake power. Take your bike to a safe place to run in the brake.
Reach adjust is done with a 2mm Allen key. Turning key clockwise: lever blade
moves away from the handlebar, turning counterclockwise: blade moves to the handleb-
ar.
