Removal
- Disconnect the oil line from the calliper, collecting
the oil in a container.
- Remove the clamps highlighted in the diagram.
- On refitting tighten the bolts to the prescribed tor-
que.
- Perform bleeding procedure on the system.
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 in the calliper body:
- sealing rings (1-2);
- small pistons(3);
- place the OR seal in a calliper body (4).
- Join the internal and external body with the as-
sembly bolts. Refit pads and bleed air (see pre-
ceding paragraphs).
- Position the calliper on the disc and lock to the
mounting by tightening the bolts.
- Tighten the union on the calliper to the prescribed
torque.
Before fitting, the parts must be perfectly clean and
free of traces of oil, diesel fuel, grease, etc..
They should be washed thoroughly in denatured
alcohol before proceeding.
The sealing rings must be immersed in the liq-
uid used; the use of protective PRF1 is allowed.
