Brake Oil:
MAGURA disc brakes use a transmission medium low viscosity mineral oil,
the
MAGURA ROYAL BLOOD
. Contrary to DOT brake fluid 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!) Use exclusively
MAGURA ROYAL BLOOD
, any other oil will damage the
seals of your brake what will result in total failure of the brake!
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 that cause poor braking
performance with possible serious accidents!
As to hints about repairs of the hose see page 15 onwards.
Brake pads: wear, control and replacement
Brake pad wear:
The brake pads are subject to wear due to friction between rotor and
pads. All Louise disc brakes 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 procedure. 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 fully 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, the pistons could
be damaged otherwise.
