- I think the Milano at least has the same ATE caliper as on the
- Alfettas: I don't know about the reborn Giuliettas. On the Alfetta the
- four screws turn this way:
- The outer pad screw on each side is a simple screw with an Allen head
- and a separate lock nut. The lock nut sits down in a depression so it
- is hard to turn at the same time that you use an allen wrench, but I
- ground a cheap box wrench to make a special tool for it. Since these
- screws DO have lock nuts they turn in a "natural" direction, the same
- on both sides.
- The inner screw is driven through a right-angled gear from a hex shaped
- shaft: You turn the shaft (I just use a small socket) which runs at
- right angles to the screw, sort of from above and rear, and it turns
- the screw which is parallel to the disc piston axis. There is no lock
- nut on this. As such it is not the same on both sides, supposedly so
- that the normal vibration and such will affect both the same way. I
- don't see this having much effect, but the result is that the inner
- screw on the left side caliper turns clockwise to tighten while the
- one on the right side turns counterclockwise to tighten. I remember
- this by thinking "the left side is right handed".
- BTW don't turn these too far without paying attention to what is
- happening: If you unscrew the outer ones too much you will discover
- brake fluid running around the threads, while if you loosen the inner
- ones too much (turning the hex after the screw is actually at the end
- of its travel) the hex piece may force its retaining clip out of the
- way and come out. It can be put back without much trouble but it is a
- surprise!
