14.12.3.2 Adjusting brake block holder distances (Magura HS models)
The following describes how to adjust brake block holder distances, using the example
of a Magura HS.
The distance between the rim and brake
block holder is adjusted to 1–2 mm/
0.04–0.08".
1. Loosen the pressure point adjustment
screw on the brake lever by turning it
anticlockwise. Ensure that you do not
unscrew it completely.
2. Turn the brake boss screw
anticlockwise until the brake boss can
be moved.
3. Press the brake cylinders and brake
block holders against the rim.
4. Align the brake boss so that the brake
block holders are parallel to the rim and
the distance between the upper edge of
the brake pad and the tyre is 2 mm/
0.08".
5. Carefully operate the brake lever so that
the brake boss does not slip.
6. Slowly release the brake lever until the
distance between one brake block holder
and the rim is 1–2 mm/0.04–0.08"
(see “Illustr.: Hydraulic rim brake”).
