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.
- Secure the tube connection to the caliper with the
required torque.
- Before reassembly, the parts must be perfectly
clean and bear no traces of oil, diesel fuel,
grease , etc.. They must therefore be washed thor-
oughly in denatured alcohol before proceeding.
Immerse the seals in brake fluid ; the use of pro-
tective agent PRF1 is tolerated.
CAUTION
RUBBER PARTS SHOULD NEVER BE LEFT IN ALCOHOL
FOR LONGER THAN 20 SECONDS.
AFTER WASHING, THE PIECES MUST BE DRIED WITH A
BLAST OF COMPRESSED AIR AND A CLEAN CLOTH.
