To prevent brake fluid from spilling, draw
off some of brake fluid from tank before
pushing back piston. This requires a syringe
used exclusively with brake fluids. Brake
fluid is poisonous and therefore must not
be drawn out through a hose by mouth.
2. Clean seat and guide surface of brake pads
in caliper with gasoline or a cylindrical
brush. Never use solutions containing
mineral oils or sharp edged metal tools.
Brake pad recess play: 0.4 to 0.6 mm.
3. Check position of piston. Edges of
shoulder on piston must be parallel to
guide surface of brake pad. The shoulder
(setback surface) must face down on rear
axle and up on front axle (toward brake
disc inlet).

4. Install brake pads. Guarantee a play of
0.4 to 0.6 mm for brake pads in recess
by pertinent steps, if necessary (replace-
ment of spring plates *, cleaning guide
surfaces on brake pads, replacement of
brake pads).
Note
Apply a light coat of grease on seats and
guide surfaces to prevent seizure of brake
pads in brake calipers due to corrosion.
Use Optimoly HT (Cu Paste) or Plastilube
(Schillings, Postfach 1703,7080 Aalen).
