6 For further dismantling it is virtually essential
to have Ford tool 12-007. This tool appears to
be a cut-down adjuster nut with a handle for
turning it. In the workshop it was found that
the piston adjuster nut could be used to
compress the spring if it were turned with
circlip pliers (see illustration). This works well
enough for dismantling, but reassembly
proved extremely difficult because of the
limited clearance between the skirt of the nut
and the caliper bore.
7 Having compressed the adjuster spring just
enough to take the load off the circlip, release
the circlip inside the caliper bore. Remove the
spring compressor, then extract the circlip,
spring cover, spring and washer (see
illustrations). 8 A long thin pair of circlip pliers will now be
needed to release the key plate retaining
circlip from the caliper bore (see illustration).
With the circlip removed, the pushrod and key
plate can be pulled out.
9 Remove the handbrake strut from the
caliper bore.
10 Remove the handbrake lever return spring
and stop bolt. Pull the lever and shaft nut out
of the caliper. Prise out the shaft seal.
11 Clean up the handbrake shaft using wire
wool; renew the shaft if it is badly corroded.
The shaft bush in the caliper can also be
renewed if necessary. Pull out the old bush
with an internal puller or slide hammer; press
in the new bush to 7.5 mm (0.30 in) below the
shaft seal lip (see illustration). The slot in the
side of the bush must line up with the pushrod
bore in the caliper. 12 Having renewed components as
necessary, commence reassembly by
smearing a little brake grease or anti-seize
compound on the handbrake shaft and bush.
13 Fit a new handbrake shaft seal to the
caliper. Pass the shaft through the seal and
into the caliper, being careful not to damage
the seal lips.
14 Refit the handbrake lever stop bolt and
return spring.
15 Refit the handbrake strut, lubricating it
with brake grease.
16 Fit a new O-ring to the base of the
pushrod. Refit the pushrod and the key plate,
engaging the pip on the key plate with the
recess in the caliper. Secure the key plate with
the circlip.
