REAR DISC BRAKE‘he rear brake is the
AD30P type, featuring highly
tifficient heat dissipation, quick recovery of braking
force when wet, and highly stabilized braking force.The brake system incorporates an auto adjuster that
automatically adjusts the clearance between the
pad and brake disc when
t.he brake pedal is
depressed.

. *the mounts, the principal axis of inertia support
system is employed.
This principal axis of inertia support system of
mounting functions to support the upper
part of the
engine and the upper part of the transaxle, thereby
effectively suppressing engine vibrations. Note that
there are the following features at the various
installation parts.
lThe transmission of engine vibration to the body
is reduced by the installation, via bushings, of
the centermember to the body.
lThe insulators each have a cavity that serves to
effectively absorb vibrations.

m/ithin the fuel tank are the electric fuel pump, the
.ank filter, and the fuel gauge unit.
-I he fuel tank has the following features:
lThe fuel tank is located below the rear seat floor,thus giving it protection in the event of a
rear-end collision.
<2WD>l The fuel tank is located under the engine
compartment floor instead of installing it under
the rear seat floor where the rear axle is located.

lA baffle plate arrangement is used at the proper
place within the fuel tank in order to prevent the
generation of abnormal noise caused by the
undulation movement of the fuel.
l A chipping-protection coating has been applied
at the lower part of the fuel tank in order to
