L
EBT (Easy Bleed Technology) makes it easy to bleed the brake.
L
The only difference between bleeding and filling – if any – is the
amount of oil required – the procedure is identical.
L
Always fill at the brake calliper, never at the brake lever!
Loss of oil and irreparable damage to the braking system.
Open the screw plugs for bleeding and filling only.
Use MAGURA
Royal Blood
(mineral oil) exclusively for bleeding
and filling – never DOT brake fluid.
L
Because MAGURA
Royal Blood
does not age, it is not necessary to
bleed or refill your MAGURA brake regularly. Do this only if one of
the following reasons requires it:
Ö
The brake does not respond immediately when the brake lever is
actuated.
Ö
Pressure point is not clearly defined, it is spongy or does not
remain constant.
Ö
After changing the brake hose.
L
To bleed or fill your MAGURA brake you will need the MAGURA
Service Kit
or the MAGURA
Pro Bleed Kit
– available from dealers.
)
Insert barbed fitting
tightly into the filling line by hand
.
)
Fill filling syringe
with MAGURA
Royal Blood
.
)
Make sure that there is no air in the filling syringe and filling line.
)
Pull the piston of the bleeding syringe
out as far as the stop.
Ö
Piston base is above bleed bore
.
L
If your bleeding syringe does not have the bleed bore, you can
make it yourself – the easiest way is to use a Ø 2 mm drill bit for
wood or metal.
L
At the right brake lever:
clockwise
in “Plus” (+) direction.
At the left brake lever:
counterclockwise
in “Plus” (+) direction.
)
Rotate rotating dial (BAT)
to the stop in the "Plus" (+) direction
)
Remove the wheel.
)
Carefully press brake pads apart to the stop with transport device
or a wide screwdriver.
Ö
All brake pistons
are in fully extended position
.
)
Removing brake pads – see
)
Screw in brake pad locking screw
)
Insert transport device
between the brake pistons from below
until it locks.
Use two transport devices per brake calliper with 4-piston brake
callipers and fasten them with a rubber ring or similar if neces-
sary!
)
Align brake caliper vertically.
L
If your assembly stand makes it impossible to align the brake
calliper vertically, you will have to unscrew it to bleed it. We always
recommend this procedure, because it is better to hold the brake
calliper above the level of the brake lever on completion of the
bleeding process and before removing the filling syringe to prevent
oil loss.
)
Unscrew the screw plug
from the filler hole of the brake calliper.
)
Screw the barbed fitting of the filling syringe
into the filler hole
and tighten with tightening torque of
4 N·m (35 lbf·in)
.
)
Loosen the bottom clamping screw
)
Turn the brake lever so it is pointing horizontally forwards or
backwards
)
Tighten the bottom clamping screw
with tightening torque of
4 N·m (35 lbf·in)
.
)
Unscrew the EBT screw
from the bleed hole
