serious or fatal injury.
MAGURA type HS 11, HS 22 and HS 33 rim brakes are designed and
i­ntended exclusively
–– for installation on conventional touring, trekking and mountain bikes
with forks and frames that possess suitable mounting fixtures (cantilever sockets), as well as on their conventional – straight – handlebars.
MAGURA type HS 11, HS 22 and HS 33 brake levers are designed and
intended exclusively
–– for installation on conventional touring, trekking and mountain bike
handlebars.
MAGURA rim brakes are designed and intended exclusively
–– for use with wheels that have rims with the corresponding brake track
areas.
–– for the specified application – see Specifications, page 13.

­combined and used with components (brake lever, brake body, etc.) of
MAGURA disc brakes!
Basic safety instructions
Always remember that riding a bicycle entails risk both for the rider and
other road users, and for the bicycle and its components. Despite the use
of safety gear and complete safety equipment, accidents that cause
­serious or fatal injury can occur.
Always use your common sense and avoid any unreasonable actions!
Installation & Maintenance
Danger of accident due to damaged brake caused by incorrect or
­impermissible installation work.
–– Never overestimate your technical capabilities. Commission a specialist
workshop for bicycles or an authorized MAGURA service centre with all
installation and maintenance work. This is the only way to ensure that
work is conducted in a professional manner.
–– Never make any changes (e. g. grinding/painting etc.) to your MAGURA
product that are not specifically permitted and described in the owner's
manual.
–– Always observe all min./max. values stated – see Technical Specifications,
page 13.
–– For assembly steps that require a specific tightening torque for a screw
union, always use a torque wrench set up for the required torque.
–– Always maintain your bicycle in technically perfect working order.
Danger of accident due to improper accessories.
–– Use only MAGURA original parts and lubricants.
–– Use only original MAGURA brake shoes and for bleeding and filling use
MAGURA Royal Blood (mineral oil).
–– Never use DOT brake fluid.

your wheels is fitted correctly and that your wheels will not work loose.
–– Before each trip, make sure your wheels move freely and do not contact
the brake pads at any point.
–– Before each ride, make sure that the handlebar and stem are correctly
fitted and will not twist.
–– Before each trip, make sure that both brakes are closed – see Opening
brake for dis-/mounting the wheel, page 20.
–– Before each trip, make sure that your brakes operate correctly – the
pressure point must be clearly perceptible and does not change when
the brake lever is pulled, the brake pads contact the brake track area
completely without contacting the tires.
–– Before each trip, make sure that your brakes are not damaged in any way,
including with the brake lever pulled (e. g. traces of oil, cracks, etc.).
–– Before each trip, make sure that the brake track area of your wheels
and the brake pads have not reached their wear limits and are free
from lubricating substances (oil, grease, silicone, wax, etc.).
–– After each crash, check your brake for damage and make sure it
­operates correctly.
–– Never use your brake if damage (e. g. traces of oil, cracks, etc.) is
­visible, you can hear unusual noises or if you have any doubts about its
integrity. In this case, have your brake checked in a specialist bicycle
workshop or directly by MAGURA Service.
Transport & Storage
Particularly in wet conditions your braking distance will be significantly
increased – always ride cautiously and be ready to brake.
–– Always use the front and rear wheel brakes simultaneously.
–– Always observe the traffic regulations in the country where you are
riding (lighting, reflectors, etc.).
–– When riding, always wear a high quality (e.g. ANSI certified),
­undamaged cycling helmet and clothing that fits snugly but does not
impair your actions.
–– Only ride your bicycle if you are in good physical condition and your
bicycle and all of its components are in perfect working order.
Danger of accident due to damaged components.
–– Make sure that brake hoses cannot be kinked when you pack your
bicycle.
–– Do not store your MAGURA brake at ambient temperatures below
-15 °C (5 °F) and above 55 °C (131 °F).
LLIt is not necessary to drain your MAGURA brake before transporting it
by air.
Protection of the environment
Dispose of used lubricants and oil correctly and in accordance with the
legal requirements – never discard them in the sewage system or in the
ground.

LLA thin wire may be helpful for inserting the brake hose through the
bicycle frame. .
Run it in the opposite direction through the outlet to the inlet of the
frame and fix it to the end of the brake hose with adhesive tape.
­However, do not insert the wire into the brake hose – oil loss!.
Carefully pulling with the wire and pushing the brake hose at the same
time will make it easier to find the outlet.
LLBefore installing your brake decide which brake lever (right or left) you
want to allocate to your front wheel or rear wheel brake.
Danger of accident due to restricted or blocked steering movement because brake hose is too short or too long.

Regular
LLHow frequently you need to maintain your MAGURA product depends
on how often you use it, but also on weather conditions..
Perform the following maintenance steps more frequently if you use
your bicycle in extreme conditions (rain, dirt, high mileage, etc.)..
If you are a frequent user, also consider the fact that this exposes your
MAGURA product to more wear and thus requires more frequent
­maintenance intervals and checks.
Corrosion and material damage due to water penetration.
)) Make sure that the pressure point is clearly defined – not spongy – and
does not remain constant..
Bleed the brake if necessary.

)) At regular intervals, check and if necessary tighten the screws on the
brake lever [A1], cantilever socket (3) and adapter (4) [B8].
)) At regular intervals, check the clamping of the quick release lever – see
Applying brake, page 20.
–– Never use a pressure or steam cleaner to clean your bicycle – the seals
on your bicycle components are not built to withstand this pressure.
–– You should even exercise care if you use a water hose. Never point the
water jet directly at seal areas [K1].
)) Clean the brake and brake track areas with water, detergent and a
brush.
)) Clean brake pads and brake track areas on the wheels with suitable
degreasers (e.g. brake cleaner, white spirit, etc.).

LLThe only difference between bleeding and filling – if any – is the amount
of oil required – the procedure is identical.
LLAlways fill at the brake cylinder, never at the brake lever!
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.
LLBecause 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:
ÎÎ The brake does not respond immediately when the brake lever is
­actuated.
ÎÎ Pressure point is not clearly defined, it is spongy or does not remain
constant.
