EBT (Easy Bleed Technology) makes it easy to bleed the brake.
L
The only difference between bleeding and filling – if any – is the
L
amount of oil required – the procedure is identical.
Always fill at the brake calliper, never at the brake lever!
L
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.
Because MAGURA Royal Blood does not age, it is not necessary to
L
bleed or refill your MAGURA brake regularly. Do this only if one of
the following reasons requires it:
The brake does not respond immediately when the brake lever
Ö
blade is actuated.
Pressure point is not clearly defined, it is spongy or does not
Ö
remain constant.
After changing the brake hose, brake calliper or brake lever.
Ö
To bleed or fill your MAGURA brake you will need the MAGURA
L
Service Kit or the MAGURA Pro Bleed Kit – available from dealers.
Insert barbed fitting tightly into the filling line by hand

Use two transport devices per brake calliper with 4-piston brake

sary!
Align brake calliper vertically.
)
If your assembly stand makes it impossible to align the brake
L
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.
