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
blade is actuated.
Ö
Pressure point is not clearly defined, it is spongy or does not
remain constant.
Ö
After changing the brake hose, brake calliper or brake lever.
L
To bleed or fill your MAGURA brake you will need the MAGURA
Service Kit or the MAGURA Pro Bleed Kit – available from dealers.

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.

At the right brake lever: clockwise in “Plus” (+) direction.
At the left brake lever: counterclockwise in “Plus” (+) direction.

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 calliper 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
(
