guide pin bolt while holding the guide pin with
a second spanner (see illustrations).
3 Pivot the caliper body upwards and tie it
up, using a length of string, under the
wheelarch (see illustration).
4 Lift out the two brake pads together with
their shims then, where fitted, remove the
upper and lower anti-rattle shims from the
caliper carrier bracket (see illustrations). If
the pads are to be re-used, identify them so
that they can be refitted in their original
positions.
5 Remove the heat shield from the caliper
piston (see illustration).
6 Brush the dust and dirt from the caliper,
piston, disc, and pads, but do not inhale it, as
it is injurious to health.
7 Rotate the disc by hand, and scrape away
any rust and scale. Carefully inspect the entire
surface of the disc, and if there are any signs
of cracks, deep scoring or severe abrasions,
the disc must be renewed.
8 Inspect the caliper for fluid leaks around the
piston, signs of corrosion, or other damage.
Check the guide pin rubber boots for
condition, and the pins themselves for free
movement in the carrier bracket. Renew any
suspect parts as necessary, with reference to
Section 5.
9 If new pads are to be fitted, it will be
necessary to push the caliper piston back into
its bore to accommodate the new, thicker
pads. To do this first remove the dust cap,
then fit a tube over the end of the bleed
