Disassembly
CAUTION!
• Clean around caliper with brake fluid before disassembly.
• Be careful not to damage inside (bore side) of cylinder.
1) Remove piston with air blown into flexible hose bolt installation hole.
WARNING!
Do not apply too highly compressed air
which will cause piston to jump out of
cylinder. Place a cloth (1) to prevent piston
from damage. It should be taken out
gradually with moderately compressed air.
Do not place your fingers in front of piston
when using compressed air.
2) Remove cylinder boot.
3) Remove piston seal using a thin blade like a thickness gauge, etc.
4) Remove bleeder plug and cap from caliper.

Assembly
Assemble parts in reverse order of disassembly,
observing the following instructions.
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 seal or cylinder boot to cylinder, apply brake fluid to them.
• Install a new piston seal into groove in cylinder securely making sure that it is not
twisted.
• Before installing caliper to carrier, check for slid pin smooth movement in thrust
direction.
• After reassembling brake lines, bleed air from them.
• Install piston seal, boot and piston to caliper referring to the following instructions.
1) Replace with a new piston seal (1) at every overhaul. After applying rubber grease (included in repair kit)
or brake fluid, fit piston seal (1) into groove in
cylinder taking care not to twist it. 2) Before inserting piston (1) into cylinder, apply rubber
grease (included in repair kit) or brake fluid to new
boot “a” and install it onto piston as shown.
3) Fit boot as it is in figure into boot groove in cylinder with fingers.
4) Insert piston into cylinder by hand and fit boot in boot groove in piston.
