Immerse the distance piece in boiling water and
while still hot tap the distance piece onto the
stub axle with a tubular drift until It clamps the
splash guard to the stub axle carrier. The hub
end ·float is set, see under "Front hubs-To
adjust" in Section F.

The hub end float is set, see under "Front hubs­
To adjust" In Section F.
All Models
Ensure that the splash guard does not foul the brake
disc.
DISCS
Run-out
Excessive run-out on the discs will cause knocking
back of the pistons which may create Increased
pedal travel when the brakes are applied.
Before checking the run-out, hub end-float should
be eliminated by tightening the hub retaining nut,
readjusting it at the end of the test. (See Section F,
"front Hubs-to adjust"). After tightening the
retaining nut, check that the hub can still be
rotated.
A dial test indicator should then be clamped to the
caliper body so that the stylus bears on the disc at a
point approximately I in. (25·4 mm) from the outer
edge. Revolve the disc and check the indicator
reading; the maximum reading on the gauge should
not exceed 0·004 in. (0·10 mm).
When the disc has suffered damage or has become
excessively scored, it must be renewed.
To remove and refit
I. Apply the handbrake, Jack up the front of the
car and remove the road wheel.
2. Remove the caliper from the stub axle carrier,
see under "Caliper-To remove and refit" and
suspend
nearby
without straining the flexible
hose.

piece.
3. Remove the hub assembly from the stub axle,
see under "Hubs-To remove and refit" in
Section F.
4. Remove the disc from the hub by withdrawing
four bolts and tab washers or washers.
5. Refitting is the reverse of the removal sequence
but particular attention must be given to the
followlng:-
(i) Ensure the fitting faces of the hub and
disc are free from dirt and burrs before
assembly. In the Instance of replacement
discs ensure Its protective coat Is
washed
off.
(ii) The four bolts are tightened to the torque
given In the "General Data Section" but
when tab washers are used on the bolts,
do NOT turn up the tabs until AFTER the
disc run-out has been checked.
(111) The hub assembly Is fitted, see under
"Front Hub-To remove and refit", but
the hub end float is set AFTER the disc
run-out has been checked.
