Overhaul
- Remove the calliper assembling bolts and take out the internal bodies and components. If necessary,
in order to make it easier to take out the plungers, inject (shorts blasts of) compressed air through the
brake fluid pipe.
- Check that the cylinders of the internal and external body of the calliper do not show scratches or signs
of erosion; otherwise, replace the entire calliper.
CAUTION
ALL THE INTERNAL COMPONENTS MUST BE REPLACED EVERY TIME THE CALLIPER IS
SERVICED.
Refitting
Insert the following parts into the calliper half bod-
ies:
- sealing rings (1-2);
- pistons (3);
- fit O-ring seal (4) in one of the pump bodies.
- Couple the inner and outer bodies by means of
the coupling bolts. Fit the pads and bleed air from
the system (see previous paragraphs).
- Position the caliper on the disc and fasten it to
the support, tightening the bolts.
