Here is what Alldata says:

WHeel Bearing adjustment:
-Remove front wheels
-secure disc to hub assembly
-force pads away from brake disc
-remove bearing hub cap
-remove radio interference suppression contact spring
-loosen internal bolt of clamping nut, tighten clamping nut while
simultaneouly turning the hub until hub can only just be turned. -loosen
clamping nut approximately 1/3 turn and relieve tension by striking stub
axel with a plastic mallet. -check endplay with suitable dial indicator
by pulling and pushing on the flange.  Turn wheel several times before
each measurement.  Endplay obtained should be .00039 - .00078 inch
(.01-.02 mm) -tighten internal bolt of clamping nut -pump brakes several
times before test driving vehicle

Rotor/disc replacement:
-remove hex-head bolts from caliper and remove caliper, support by means
of suitable hook -if equipped with "Starting torque compensation" remove
bolts from brake hose holder, then support caliper as above -remove disk
from axle flange -remove any rust or burrs from contact surfaces between
disk and axle flange. -Coat fitted seat of flange with "Molykote Paste
U" or equivalent -If rotor is new remove corrosion protection from rotor
with cleaning solvent "Brake cleaing spray" -mount rotor to hub ensuring
that fitted pin correctly enters brake disk -install caliper using NEW
self-locking bolt  ((I use a wee bit of Locktite)) -Torque bolts to 90
Nm (66-67 Ft Lbs) -pump brakes several times before test driving vehicle


Hope that helps..
