13.7a Removing disc retaining screws (jacking holes arrowed)
Using a piece of wire or string, tie the caliper to
the front suspension coil spring to avoid placing
any strain on the hydraulic brake hose.
7 Use chalk or paint to mark the relationship
of the disc to the hub, then remove the two
screws securing the brake disc to the hub and
remove the disc. If the disc is a tight fit on the
hub it can be drawn off by screwing two bolts
into the jacking holes provided (see
illustrations).
Refitting
8 Refitting is the reverse of the removal
procedure, noting the following:
a) Ensure that the mating surfaces of the
disc and hub are clean and flat.
b) Align (if applicable) the marks made on
removal.
c) If a new disc has been fitted, use a
suitable solvent to wipe any preservative
coating from the disc before refitting the
caliper.
d) Tighten the disc retaining screws, caliper
bracket bolts and roadwheel nuts to their
specified torque wrench settings.
14 Pressure regulating valve -
testing, removal and refitting 3
Testing
1 The pressure regulating valve is mounted
on the right-hand side of the engine
compartment bulkhead.
2 Specialist equipment is required to check
valve performance. If the valve is thought to
be faulty, the vehicle should be taken to a
suitably equipped Rover dealer for testing.
However, in the event of an internal failure,
brake fluid will seep from the plug on the front
face of the valve which is situated directly
above the lower two hose unions (see
illustration). Repairs are not possible and, if
faulty, the valve must be renewed.
Removal
3 Disconnect the sender unit wiring
connector and unscrew the master cylinder
reservoir filler cap. Place a piece of polythene
over the filler neck and securely refit the cap
(taking care not to damage the sender unit).
This will minimise brake fluid loss during
subsequent operations. As an added
precaution, place absorbent rags beneath the
pressure regulating valve brake pipe unions.
4 Wipe clean the area around the brake pipe
unions on the pressure regulating valve, then
make a note of how the pipes are arranged for
reference on refitting. Unscrew the union nuts
and carefully withdraw the pipes. Plug or tape
over the pipe ends and valve orifices to
minimise the loss of brake fluid and to prevent
the entry of dirt into the system. Wash off any
spilt fluid immediately with cold water.
5 Slacken the two bolts which secure the
valve to the bulkhead and remove it from the
engine compartment.
Refitting
6 Refit the pressure regulating valve to the
bulkhead and tighten its mounting bolts
securely.
7 Wipe the brake pipe unions clean and refit
them to the valve, using the notes made on
14.2 In the event of failure, fluid will seep
from pressure regulating valve plug

dismantling to ensure they are correctly
positioned. Tighten the union nuts to the
specified torque.
8 Remove the polythene from the master
cylinder reservoir filler neck and bleed the
complete hydraulic system.

16 Rear brake shoes - renewal

Warning: Brake shoes must be
renewed on both rear wheels at
the same time. Never renew the
shoes on only one wheel as uneven
braking may result.
Removal
1 Remove the brake drum.
2 Working carefully and noting all
precautions, remove all traces of brake dust
from the brake drum, backplate and shoes.
3 Measure the thickness of friction material
remaining on each brake shoe at several
points. If either shoe is worn at any point to
the specified minimum thickness or less, all
four shoes must be renewed as a set. Also,
the shoes should be renewed if any are fouled
with oil or grease as there is no satisfactory
way of degreasing friction material once
contaminated.
4 If any of the brake shoes are worn unevenly
or fouled with oil or grease, trace and rectify
the cause before reassembly.
5 To remove the brake shoes, first remove
the shoe retainer springs and pins, using a
pair of pliers to press in each retainer clip until
it can be rotated through 90º and released.
Ease the shoes out one at a time from the
