1. Repair of a HS 11 main hose with barbed adaptor connection.
2. To do this clamp the hose as shown with the help of the two clamping jaws into
a vice. 1,5cm of the hose have to stick out of the clamp. Use a nylon mallet to tap the
barbed fitting into the tubing. The barbed fitting must be installed as shown. Never
use a lighter or a heatgun to soften the hose.
3. Screw the repaired hose into the prepared thread.
4. Correctly installed repaired hose on an HS 11. The barbed fitting is flush with
the brake lever (arrow). The brake now has to be re-filled as described in the chapter
'filling and bleeding'.
Further repair tips
In case of a damaged brake-cylinder crossover-hose, proceed as described above
from points 1 to 4.
Spare brake levers and slave cyclinders are delivered „dry". If you have to replace
a brake lever or slave cylinder, the MAGURA system has to be bled twice after changing
the defective item. Activate the lever blade after the first bleed to chase all air bubbles
and to make sure that the oil is well distributed in the new part.
Leaking brake levers and slave cylinders have to be replaced as complete
units. Due to product liability reasons MAGURA neither offers spare pistons nor
internal seal repair kits.
