7. Maintenance

Brake Oil: MAGURA disc brakes use a transmission medium low viscosity mineral
oil, the biodegradable MAGURA Blood. Contrary to DOT brake liquid the MAGURA 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 unbelie-
vable is a fact: you can use your brakes over years without having to touch them
(except brake pad 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 Clara and the Julie disc brake feature a fully
automatic pad wear adjustment. Regularly check the thickness of your brake
pads and replace them, if necessary!
Control and replacement of the brake pads
Never touch either the rotor or the brake caliper after long braking as this
may cause serious burns.
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 caliper body.
Never push back the pistons without the brake pads mounted!
2. Remove the cotter pin that holds the brake pads.
3. Pull out the brake pads. Their „ears" make this very easy. Clean the pads with a
dry rag that is free of oil and grease.
