Overhaul
Proceed as follows:
1) remove the two male hexagonal screws (1) and
take out the two pads (10);
2) remove the two male hexagonal screws (2) and
remove the reaction plate (3);
3) take out the fixed plate (4) from the guide;
4) remove the internal elements from the floating
body (5) with the help of short blows of com-
pressed air through the brake fluid pipe in order to
facilitate the expulsion of pistons (6).
5) Check:
- that the plates and the body are whole and in
good condition;
- that the cylinder and the floating body of the cal-
liper do not show signs of scratches or erosion,
otherwise replace the entire calliper;
- that the guides of the fixed plate are not scratched
or eroded, otherwise replace the entire plate;
- that the brake pad check spring works properly.
Refitting
1) insert the pistons (6) and the sealing rings (7) in
the body;
2) place the guide rubbers (8) and refit the fixed
plate (4);
3) assemble the reaction plate (3) tightening the
screws (2), insert the brake pad check spring (9)
and then the pads, fixing them with the corre-
sponding screws (1);
5) place the calliper on the disc and lock it to the
strut by tightening the fixing screws;
6) fix the pipe joint on the calliper at the prescribed
torque.
Functioning
This is a floating type calliper.
It takes advantage of the action and reaction prin-
ciple to obtain the thrust for both pads.
