L L EBT.(Easy.Bleed.Technology).makes.it.easy.to.bleed.the.brake.
L L The.only.difference.between.bleeding.and.filling.–.if.any.–.is.the.amount.
of.oil.required.–.the.procedure.is.identical.
Loss of oil and irreparable damage to the braking system.
Î – Open.the.lock.screws.for.bleeding.and.filling.only.
Î – Use.MAGURA.Royal Blood.(mineral.oil).exclusively.for.bleeding.and.
filling.–.never.DOT.brake.fluid.
Î – Never.remove.the.stud.bolts. ( 3 ) . [ F1 ] . [ M1 ] .
L 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:
О О Brake.does.not.respond.immediately.to.a.pull.on.the.brake.lever.(even.
though.the.brake.cable.is.correctly.tensioned.with.RT.C).
О О
Pressure.point.is.not.clearly.defined,.it.is.spongy.or.does.not.remain.
constant.
О О After.changing.the.brake.hose.(left-right).at.the.brake.lever.or.converter.
О О
After.replacing.the.brake.hose.
L L To.bleed.or.fill.your.MAGURA.brake.you.will.need.the.MAGURA.service
kit.or.the.MAGURA.Profi bleed kit.–.available.from.dealers.
. ) Insert.barbe. ( 1 ) .tightly.into.the.filling.line.by.hand. [ L1 ] .
. ) Fill.filling.syringe. ( 2 ) .with.MAGURA.Royal Blood.
. ) Make.sure.that.there.is.no.air.in.the.filling.syringe.and.filling.line.
. ) Remove.the.piston.of.the.bleeding.syringe. ( 3 ) .
. ) Make.sure.that.the.pressure.point.adjusting.screws. ( 1 ) .are.unscrewed.
to.the.stop.(-). [ H2 ] .
. ) Make.sure.that.the.brakes.are.closed.
.– see.
Opening the brake for dis-/mounting the wheel ,.page.22.
. ) Unscrew.the.screw.plug. ( 4 ) .from.the.filler.hole. ( 5 ) . [ L2 ] .
. ) Screw.the.barbed.fitting.of.the.filling.syringe. ( 2 ) .into.the.filler.hole.and.
tighten.to.a.tightening.torque.of. max. 4 N·m (35 lbf·in). [ L3 ] .
. ) Unscrew.EBT.screw. ( 6 ) .from.the.bleed.hole. ( 7 ) . [ L4 ] .
. ) Insert.the.bleed.syringe. ( 3 ) .tightly.into.the.bleed.hole. [ L5 ] .
. ) Position.the.bicycle.so.
for.RT.TT.the.brake.lever.is.tilted.slightly.forward..
for.RT.C.the.bleed.syringe.is.tilted.slightly.upwards.
. ) Press.MAGURA.Royal Blood slowly.out.of.the.filling.syringe. ( 2 ) .through.
the.brake.system.–.tap.lightly.on.the.brake.body,.brake.lever.(RT.TT).
and.converter.(RT.C).during.this.process.
О О
This.loosens.air.bubbles.and.they.rise.into.the.bleed.syringe. ( 3 ) . [ L5 ] .
. ) Continue.the.process.until.you.cannot.see.any.more.air.bubbles.
О О The.brake.system.has.been.bled.
Oil loss when removing the bleed syringe.
Î – Have.a.clean.cloth.at.hand.
Î – Block.the.top.hole.with.your.thumb.before.removing.the.syringe.
Î – After.removal.quickly.place.a.finger.on.the.tip.of.the.syringe.
. ) Pull.the.bleed.syringe.out.of.the.bleed.hole.
. ) Screw.the.EBT.screw. ( 6 ) .into.the.bleed.hole. ( 7 ) .and.tighten.to.a.tighten-
ing.torque.of. max. 0.5 N·m (4 lbf·in).. [ L4 ] .
. ) Unscrew.the.barbed.fitting.of.the.filling.syringe. ( 2 ) .from.the.filler.
hole. [ L3 ] .
. ) Screw.the.screw.plug. ( 4 ) .into.the.filler.hole. ( 5 ) .and.tighten.to.a.tighten-
ing.torque.of. 4 N·m (35 lbf·in). [ L2 ] .
. ) Thoroughly.clean.up.any.oil.residues.on.any.surfaces.–.particularly.on.
brake.track.areas.and.brake.pads.
. ) Pull.and.hold.brake.lever.
. ) Make.sure.that.all.connections.are.tight.
. ) Set.the.pressure.point.– see. s etting pressure pOint
