RAPIER
Revolve the disc and check the Indicator reading;
when tab washers are used on the bolts,
do NOT turn up the tabs until AFTER
the disc run-out has been checked.
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.
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.
(IQ The four bolts are tightened to the torque
given in the "General Data Section" but
(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.
(iv) The disc run-out is checked, see under
"Disc Run-out". When the run-out is
greater than the specified figure, the disc
can be repositioned on the hub in an
attempt to obtain a more satisfactory
combination of machining tolerances.
(v) When tab washers are fitted, remove the
hub assembly and turn the tabs of the four
tab washers over the heads of the bolt
and the hub refitted.
(vi) Set the hub end float, see under "Front
hubs-To adjust" in Section F.
(vii) When a replacement disc is fitted to
Series I and II models, position the caliper
centrally astride the disc, using packing
shims and washers see under "Callper
To remove and refit."
(viii) Only when the caliper has been removed
completely from the car is It necessary to
bleed the hydraulic system of air.
REAR BRAKES
DESCRIPTION
(See Fig. 16)
The rear brakes incorporate leading and trailing
shoes operated by a single wheel cylinder. The
lower ends of the shoes locate in slots In the wheel
cylinder piston (3) and body (11), whilst the upper
ends pivot about an abutment (16), situated directly
opposite the wheel cylinder on the backplate (12).
The shoes are supported by platforms formed In
the backplate and are held in position by two
damper springs and pegs which pass through holes
in the backplate (see item 18). The shoes are
linked together by pull-off springs ( 13 and I 5),
situated between shoe webs and backplate.
When hydraulic pressure is applied, the pistons in
the wheel cylinders are thrust outwards operating
the leading shoes (14) and the cylinder bodies react
by sliding in their slots In the backplates to operate
the trailing shoes (17). When the pressure is
released the shoes are returned to their original
positions by the pull-off springs.
Adjustment for lining wear is made possible by
a
"micram" adjuster
(I)
which is attached together
with its mask
(2)
to the top edge of each leading
shoe.
Handbrake (See Fig. 11)
A cable linkage connects the handbrake to levers
housed in each rear wheel cylinder.
