GA2
calipen with
250 mm (9.7 in) diameter discs at the front, arid Type
9CH
sliding calipers with
275 mm (10.82 in) diameter discs at the rear; the rear brakes are mounted

FRONT
BRAKE PADS
To Renew
Always
change brake pads in wheel sets.
1.
After raising the front of the vehicle, remove the front wheels.
WARNING: When both front wheels are raised, do
NOT
move the road wheels
quickly from lock to lock, as this
will cause hydraul ic pressure to build
up within the steering gear,
which may cause the rubber bellows to bunt
or blow off.
2.
Remove any accumulated road filth from the area of the brake pads.
3.
Pull out the pad retaining piri clips (A), withdraw the retaining pins
(B)
antf
remove the brake pads
(C)
with the stiims (Fig .2). Note the position of the
dust shield fitted over the brake pads.
4.
To enable the new pads to be fitted, push the pistons in the calipers back
into the bores.
This
action will cause hydraulic fluid to be returned to the
master cylinder, which
if
it has recently been topped
-
up, may overflow.
To avoid this, examine the fluid level and
if
necessary, remove a quantity
of fluid
BEFORE
pushing the pistons back into ttie bores. DO
NOT
USE
REMOVED FLUID FORTOPPING
-
UP PURPOSES.
5.
Fit the new brake pads with
the shims taking care that both are fitted
correctly. The shims are marked with an arrow which MUST point in the
directiori of forward rotation of
ttie wheel. Replace the dust shield, refit
the retaining pins
and the locking clips.
