1 General information and
precautions
General information
The braking system is of the servo-
assisted, dual circuit hydraulic type. The
arrangement of the hydraulic system is such
that each circuit operates one front and one
rear brake from a tandem master cylinder.
Under normal circumstances both circuits
operate in unison. However, in the event of
hydraulic failure in one circuit, full braking
force will still be available at two wheels (see
illustrations).
On models not equipped with an Anti-lock...

shut down and the warning lamp on the
instrument panel is illuminated to inform the
driver that the ABS system is not operational.
If a fault does develop in the ABS system
the vehicle must be taken to a Rover dealer
for fault diagnosis and repair.
Precautions
Hydraulic fluid is poisonous. Wash off
immediately and thoroughly in the case of skin
contact and seek immediate medical advice if
any fluid is swallowed or gets into the eyes.
Certain types of hydraulic fluid are
inflammable and may ignite when...

Removal
1Carefully unplug the hose connection from
the vacuum servo unit taking care not to
damage the sealing grommet.
2Unscrew the union bolt securing the
vacuum hose assembly to the inlet manifold
and withdraw the hose assembly from the
engine compartment. Remove the union bolt
from the hose end and discard the sealing
washers.
Testing
3Examine the hose for damage, splits,
cracks or general deterioration. Make sure
that the check valve inside the hose is
working correctly by blowing through the
hose...

fitted to prevent expelled air and fluid being
drawn back into the system. Some kits
include a translucent container which can be
positioned so that the air bubbles can be
more easily seen flowing from the end of the
tube (see illustration).
22The kit is connected to the bleed screw,
which is then opened. The user returns to the
driver’s seat and depresses the brake pedal
with a smooth, steady stroke and slowly
releases it. This sequence is repeated until the
expelled fluid is clear of air bubbles....

2Wipe clean the area around the brake pipe
unions on the side of the master cylinder and
place absorbent rags beneath the pipe unions
to catch any surplus fluid. Unscrew the two
union nuts and carefully withdraw the pipes.
Plug or tape over the pipe ends and master
cylinder orifices to minimise loss of brake fluid
and to prevent the entry of dirt into the
system. Wash off any spilt fluid immediately
with cold water.
3Slacken and remove the two nuts and
washers securing the master cylinder to the
vacuum...

piston in as far as possible and extract the
circlip and washer. Withdraw the primary
piston assembly and spring.
20Undo the grub screw from the underside
of the master cylinder body then use the
wooden dowel to press the secondary 
piston into the body and withdraw the
secondary piston retaining pin. Extract 
the secondary piston assembly and spring. If
necessary, the piston can be dislodged by
tapping the master cylinder body on a
wooden block.
21Examine and overhaul the master cylinder
components as...

bracket and check that the rubber guide pin
gaiters are undamaged (see illustration).
Brush the dust and dirt from the caliper and
piston but do notinhale it as it is injurious to
health. Inspect the dust seal around the piston
for damage and the piston for evidence of
fluid leaks, corrosion or damage. Renew as
necessary.
8On refitting, first fit the pad retainer springs
to the caliper mounting bracket (see
illustration).
9Apply a thin smear of high-temperature
brake grease (silicone- or PBC/Poly Butyl...

the caliper piston. Note that the brake pads
need not be disturbed and can be left in
position in the caliper mounting bracket.
Overhaul
6With the caliper on the bench, wipe away all
traces of dust and dirt. Avoid inhaling the dust
as it is injurious to health.
7Withdraw the piston from the caliper body
and remove the dust seal. The piston can be
withdrawn by hand or if necessary, pushed
out by applying compressed air to the union
bolt hole. Only low pressure should be
required such as is generated by a...
