Fit new pads and damper spring into the caliper bracket, and r e f i t
the caliper body, alighing the stot i n the piston with the lug on the
brake pad backplate.
5.
F i t
new self locking bolts to secure the caliper body to the guide
pins. F i t the top bolt .first, then compress the

damper spring
and f i t the lower bolt.
Torque tighten both bolts to 3.2

Operate the footbrake several times to bring the pads to their correct
working position and to take up the handbrake adjustment.
CAUTION:
The brakes w i l l not work at f u l l efficiency u n t i l the new brake
pads have bedded-in. If, initially, the brakes are used too heavily, the
surface of the pads w i l l burn and irregular braking result. Use the brakes
gently for the first few miles and gradually build up brake effort.

HANDBRAKE
The handbrake lever connects to an actuating link which uses a compensator
lever to balance the force applied to each handbrake cable. Late cars may
be fitted with a multiplier lever pivoting on the handbrake lever mounting
plate, i n order to increase the leverage and reduce opera tor effort.
Access to the handbrake cable adjusters i s made via an aperture i n the rear
end of the
s i l l
trim panel, covered by carpet.
The cables should be adjusted to obtain a vertical position of the compensator
when the handbmke
i s
applied.
The cylindkr end covers on the brake caliper asselnblies, contain a handbrake
automatic adjustiment mechanirm to accommodate brake pad wear. Movement
of the caliper lever causes a cam to rotate and exert a force via a pushrod and
adjuster mechanism, on the caliper piston and
The 'relaxed' position of the piston i s
controlled by the piston seal i n the cylinder
wall, which pulls the piston back a specified
amount after each brake application.
As
the
brake pad wears, and the piston moves out-
wards accordingly, the ratchet teeth
'0'
are
pulled past the pawl
'A',
so keeping the
handbrake mechanism i n constant ad justment.
