Piston Seal
Excessive or uneven wear of pad lining may indicate unsmooth
return of piston.
In such case, replace rubber seal.
ASSEMBLY
Assemble parts in reverse order of disassembly, observing the
following instructions.
“A” : Grease 99000-25010
Install piston seal to caliper referring to the following instruc-
tions.
a) Replace with a new one at every overhaul. Fit piston seal
(1) into groove in cylinder taking care not to twist it.
CAUTION:
Wash each part cleanly before installation in the same
fluid as the one used in master cylinder reservoir.
Never use other fluid or thinner.
Before installing piston and piston seal to cylinder,
apply fluid to them.
After reassembling brake lines, bleed air from them.
Install a new piston seal into groove in cylinder
securely making sure that it is not twisted.
Before installing caliper to carrier, install slide pin with
grease applied into caliper carrier hole and check for
its smooth movement in thrust direction.

BRAKE DISC
REMOVAL
1) Hoist vehicle and remove wheel.
2) Remove caliper assembly by removing caliper carrier bolts
(2 pcs)
3) Pull brake disc off by using 8 mm bolts (1) (2 pcs).WARNING:
Make sure that flexible hose is not twisted when tighten-
ing joint bolt. If it is twisted, reconnect it using care not to
twist it.

During removal, be careful not to damage brake flexible
hose and not to depress brake pedal.
NOTE:
Hang removed caliper with a wire hook or the like so as
to prevent brake hose from bending and twisting exces-
sively or being pulled.
Don’t operate brake pedal with brake pads removed.
