5. Remove the sealing rings (6 and 13) by inserting
a screwdriver under the rings and prising them
out, taking great care not to damage the locat­
ing grooves. If the sealing rings are worn or
damaged they must be replaced·.
No attempt should
be made to remove the bridge bolts
Joining the two halves of the caliper. There is no point
in doing so, and In addition, the torque figures to which
the bolts are tightened are critical.
If, in an emergency, the caliper has been spilt and
in the event of the fluid channel seal
(3)
being unda­
maged, the caliper and caliper bolts should
be
thoroughly
cleaned, dried and reassembled and the bolts tightened
to
the torque readings given below. After reassembling
the unit should be
checked for fluid tightness under
maximum pedal pressures.
It should be understood that this will only provide a
temporary remedy, and the unit should be returned
to
the manufacturers for overhaul at the first opportunity.

To reassemble
I. Thoroughly clean the caliper bores with methy­
lated spirits and allow tci evaporate, then
lubricate with clean brake fluid.
2. Carefully refit the sealing rings into the larger
of the two annular grooves in each of the
caliper bores.
3. Fit the dust covers back into position with
the projecting lips inserted into the smaller
grooves In the caliper bores.
4. Insert the pistons, closed ends first, into the
bores. Fit the outer lips of the dust covers Into
the grooves in the pistons.
5. Push the pistons to the bottom of thelr cylinders
and refit the brake pads as previously described.
.6. Refit the calipers to the vehicle as pre-
viously described.
SPLASH GUARDS
Splash guards are fitted to protect the Inner faces
of the discs against grit.
On early Serles I models they are secured by
brackets to the steering arm forward mounting
bolts and caliper lower mounting bolts. On later
WSM.124
Section K (Brakes)
Serles I models* and on all Serles II models, the
splash guards are retained on the stub axles by
distance pieces and are secured to the lower bosses
of the stub axle carrier
by
nuts, brackets and bolts.
On Serles Ill models onwards, the splash guards are
secured to the hub side of the stub axle carrier by
three bolts each.
To remove and refit
Early Ser/es I models only
I. Apply the handbrake, jack up the front of the
car and remove the road wheel.
2. Remove the splash guard from the stub axle
carrier by withdrawing the bolts from the
front steering arm lug and lower caliper lug,
identifying any packing washers and shims that
may be on these bolts.
Later Serles I* and Series II models
I. Remove the caliper from the stub axle carrier,
see under "Caliper-To remove and refit",
suspend nearby without straining the flexible
hose.
2. Remove the hub assembly from the stub axle,
see under "Front hub-To remove and refit"
in Section F.
3. Support the distance piece from below, grind
the outside
edge
to cut through the case hard­
ening and spilt the distance piece with a cold
chisel and hammer blows.
4. Detach the splash guard from the mounting
brackets by removing three nuts and washers.
Serles Ill models onwards
I. Proceed with the first two operations for Late
Serles I and Serles II models.
2. Remove the splash guard from the stub axle
carrier by withdrawing three bolts and washers.
Refitting Is the reverse of the removal sequence,
but particular attention must be given to the fol­
lowing:-
