11.7 Check condition of guide pins and
gaiters before refitting pads
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 not inhale 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.
8 On refitting, first fit the pad retainer springs
to the caliper mounting bracket (see
illustration).
9 Apply a thin smear of high-temperature
brake grease (silicone- or PBC/Poly Butyl
Cuprysil-based) or anti-seize compound (eg
Holts Copaslip) to the sides and back of each
pad’s metal backing and to those surfaces of
the caliper body and mounting bracket which
bear on the pads. Fit the shims to the back of
both pads and apply a thin smear of lubricant
to the back of each shim. Do not allow the
lubricant to foul the friction material (see
illustration).
10 Install the brake pads in the caliper
mounting bracket, ensuring that the friction
material is against the disc.
11 If new brake pads have been fitted, the
caliper piston must be pushed back into the
cylinder to make room for them. Either use a
G-clamp or similar tool, or use suitable pieces
of wood as levers. Provided that the master
cylinder reservoir has not been overfilled with
hydraulic fluid there should be no spillage but
keep a careful watch on the fluid level while
retracting the piston. If the fluid level rises
above the MAX level line at any time, the
surplus should be syphoned off or ejected via
a plastic tube connected to the bleed screw.
12 Apply a thin smear of the recommended
lubricant (see above) to the circular shim and
fit the shim to the caliper piston. Pivot the
caliper body down over the brake pads then
refit the bottom guide pin bolt and tighten it to
the specified torque wrench setting.
13 Check that the caliper body slides
smoothly in the mounting bracket, then
depress the brake pedal repeatedly until the
pads are pressed into firm contact with the
brake disc and normal (non-assisted) pedal
pressure is restored.
14 Repeat the above procedure on the
remaining front brake caliper.
11.8 Fit pad retainer springs to caliper
bracket . . .
15 Refit the roadwheels, then lower the
vehicle to the ground and tighten the
roadwheel nuts to the specified torque
setting.
16 On completion, check the hydraulic fluid
level.

Warning: Brake hydraulic fluid
may be under considerable
pressure in a pipeline, take care
not to allow hydraulic fluid to
spray into the face or eyes when loosening
a connection.

and support on axle stands. Remove the
appropriate front roadwheel.
2 Minimise fluid loss either by removing the
master cylinder reservoir cap and then
tightening it down onto a piece of polythene
to obtain an airtight seal (taking care not to
damage the sender unit), or by using a brake
hose clamp, a G-clamp or a similar tool to
clamp the flexible hose.
3 Clean the area around the union, then undo
the brake hose union bolt and disconnect
the hose from the caliper. Plug the end of the
hose and the caliper orifice to prevent dirt
entering the hydraulic system. Discard the
sealing washers as they must be renewed
whenever disturbed.
4 Unscrew the two caliper guide pin bolts
whilst, if necessary, using a slim open-ended
spanner to prevent the guide pins themselves
from rotating (see illustration).
5 Carefully lift the caliper assembly off the
brake pads and remove the circular shim from
