The rear wheel has a fixed caliper. The rear caliper
assembly consists o f t w o caliper halves
7
,
do',
bolted
together, with each half containing a cylinder; a set o f
opposed pistons

; and t w o pads

.
The pad anti-
rattle springs

hold the pads in position apart from
the disc when the rear brake is n o t applied. When the
brake is applied, the pressurized fluid i s delivered to
the piston areas on both sides o f the caliper at the same
time. Each piston goes forward until it is pressed against
the disc, so no lateral movement o f the disc and caliper
is needed. There i s a drilled internal fluid passage which
is sealed by
0
ring where the t w o caliper halves join.

I f any grease or oil spills on the pads, wash it o f f
with trichloroethylene or a high flash-point solvent. Do
not use one which will leave an oily residue. I f the oil
cannot be thoroughly clean off, replace the pads.

Pad wear
Inspect the pads for wear. For the front disc brakes,
check the thickness o f the pad linings, and replace both
pads as a set if the thickness of either pad is less than
1 mm.
Fluid seal damage
The fluid seal around the piston maintains the prop-
er padldisc clearance.
I f this seal is not satisfactory,
pad wear will increase, and constant pad drag on the disc
will raise brake and brake fluid temperature.
Replace the fluid seals under any o f the following
conditions: (a) fluid leakage around the pad; (b) brakes
overheat; (c) there is a large difference i n l e f t and right
pad wear; (d) the seal is stuck to the piston. I f the fluid
seal i s replaced, replace the dust seal as well. Also, re-
place all seals every other time the pads are changed.
