Brake Oil:
MAGURA disc brakes use a transmission medium low viscosity mineral
oil, the MAGURA ROYAL BLOOD. Contrary to DOT brake liquid the MAGURA ROYAL
BLOOD does not irritate human skin or strip the paint of your frame. Moreover it does
not absorb water like DOT and does not have to be changed regularly. What sounds
unbelievable is a fact: you can use your brakes over years without having to touch them
(except brake pad check and change!)
Always make sure that the brake system does not have any leaks by
activating the lever blade, holding it and checking the hose connections and
reservoir cover for eventual leaks. Consult a trained technician in case of
leaks. Leaks cause poor braking performance with possible serious accidents!
As to hints about repairs of the hose see page 14 onwards.
Brake pads: wear, control and replacement
Brake pad wear: The brake pads are subject to wear due to friction bet-
ween rotor and pads. Both the Louise and the Louise FR disc brake feature a
fully automatic pad wear adjustment. Regularly check the thickness of your
brake pads and replace them, if necessary! CHANGE ALWAYS BOTH PADS
SIMULTANEOUSLY!
Control of the brake pad wear
Never touch either the rotor or the brake caliper after long braking as this
may cause serious burns.
Squeeze the lever blade with the wheel mounted an hold the pressure.
Check out whether the “finger” of the transport device fits in-between the “ears” of
the brake pads.
On the picture on the left this is NOT the case, the pads must be
changed!
Here the “finger” of the transport device fits between the “ears” of the brake pads.
The pads are still o.k. Remember: The lever has to be pulled during this proce-
dure. Use for this a rubber band or a cable tie.
Replacement of the brake pads
1.
Remove the wheel so that you have free access to the brake caliper.
Push both brake pads back by putting the transport device or a flat blade screwdriver
into the gap. Move the screwdriver
slowly
back and forth until both caliper pistons are
fully retracted and flush with the caliper body.
Never push back the pistons without the brake pads mounted!
