Remove the wheel so that you have free access to the brake caliper.
Push back both brake pads by putting the transport device or a flat blade screwdriver into
the gap. Move the screwdriver
slowly
back and forth until both calliper pistons are fully
retracted and flush with calliper body.
Never push back the pistons without the brake pads mounted! Open the brake
system only after having fully pushed back the brake pads.
2.
Loosen the brake lever clamping screw with a 5 mm allen key. Turn the brake lever
and ensure that the reservoir is horizontal.
3.
Slide the hose protection. Unscrew the sleeve nut on the brake lever with an
8 mm open-end wrench and pull the hose out
carefully. Hold the hose carefully to avoid
any loss of oil! Do not squeeze the lever blade with the system open!
4.
Put the hose on a workbench and shorten it with a sharp knife. The best tool is the
MAGURA cutter.
Do not use saws or pliers!
If your frame is not equipped for routing hydraulic lines you should now mount the hose
fitting kit (available as separate accessory, see magura.com) for your rear brake according
to the instructions that are included in the kit.
Hold the hose carefully so that it cannot
snap away! Cut the hose squarely! The sleeve nut can be reused. The olive cannot be
reused and must be replaced!

Press by hand a
new
insert into the hose until it is
fully seated.
Clamp the hose into

or clamp the mounting device as shown into a vice and hammer the insert

mount the hose fitting kit for your rear brake according to the instructions that are included
in the kit.

Slide on the sleeve nut and a
new
olive onto the hose. Push the hose with the sleeve
nut and the new olive
fully
into the brake lever and tighten the sleeve nut with
an 8 mm open-end wrench.
Tightening torque: 4 Nm/34 in.lbs.
6. Always check for correct installation by pulling on the hose. Make
sure that the system has no leaks. Squeeze the lever blade, hold pressure
and check hose connections and the reservoir cover for eventual leaks.
Squeeze the lever blade several times (pump) to push the pads to their proper
position until the lever feel becomes very firm. If you cannot realize this, bleed the
brake (see page 15 onwards).
