10•4 Braking system
5.3 Disc-securing spring clip
and bracket off the disc and tie them up out of
the way. Do not allow the caliper to hang on
the flexible hose.
3 Remove the spring clip which secures the
disc (see illustration).
4 Mark the relationship of the disc to the hub
if it is to be re-used, then remove the disc.
5 Refit by reversing the removal operations.
Tighten the caliper bracket bolts to the
specified torque, and check that the brake
flexible hose is not kinked or fouling in any
position of the steering wheel.
6 Pump the brake pedal to bring the pads up
to the disc.
6 Rear brake disc - removal and
refitting
1 Chock the front wheels and release the
handbrake. Slacken the rear wheel nuts, raise
and support the vehicle and remove the
relevant rear wheel.
2 Free the handbrake cable from its clip in the
suspension lower arm.
3 Remove the two bolts which secure the
caliper bracket to the hub. Lift the caliper and
bracket off the disc and suspend it without
straining the flexible hose.
4 Remove the spring clip from the wheel stud.
Mark the disc-to-hub relationship and remove
the disc.
5 Refit by reversing the removal operations.
6 Pump the brake pedal to bring the pads up
to the disc.
7.5 Lifting a front caliper off the disc
7.2 Spring clip fitted to outboard face of
front caliper
7 Front brake pads - inspection
and renewal
1 Disc pads can be inspected without
removing the front wheels, using a mirror and
a torch through the aperture in the rear face of
the caliper. If any one pad is worn down to the
minimum specified, all four pads (on both front
wheels) must be renewed.
2 To renew the pads, first remove the front
wheels, then prise free the spring clip from the
outboard face of a caliper (see illustration).
3 Disconnect the pad wear warning wires,
when fitted (see illustration).
4 Unscrew the two caliper slide bolts, using
a 7 mm hexagon key, until the caliper is free
of the bracket (see illustration).
5 Lift the caliper off the disc and remove the
pads (see illustration). Support the caliper so
that the flexible hose is not strained. Do not
press the brake pedal with the caliper removed.
6 Clean the dust and dirt from the caliper,
bracket and disc, using a damp cloth or old
paintbrush which can be thrown away
afterwards. Take care not to disperse the dust
into the air, or to inhale it, since it may contain
asbestos. Scrape any scale or rust from the
disc. Investigate any hydraulic fluid leaks.
7 Push the caliper piston back into its
housing, using the fingers or a blunt
instrument, to accommodate the extra
thickness of the new pads.
8 Fit the new pads to the caliper, being careful
not to contaminate the friction surfaces with oil
7.8a Clipping the inboard front pad into the
piston
7.3 Pad wear warning multi-plug (arrowed)
on front caliper
7.4 Undoing a caliper slide bolt
or grease. The inboard pad has a spring clip
which fits into the piston recess; the outboard
pad must have its backing paper peeled off,
after which the pad should be stuck to the
other side of the caliper (see illustrations).
9 Fit the caliper and pads over the disc and
onto the caliper bracket. Tighten the slide
bolts to the specified torque.
10 Reconnect the wear warning wires, if fitted.
11 Refit the spring clip to the caliper.
12 Repeat the operations on the other caliper,
then refit the wheels and lower the vehicle.
Tighten the wheel nuts.
13 Pump the brake pedal several times to
bring the pads up to the disc, then check the
brake fluid level.
14 Avoid heavy braking as far as possible for
the first hundred miles or so to allow the new
pads to bed in.
7.8b Both pads fitted to a front caliper
