NOTE:  Do not reuse the drained fluid. Always use Acura DOT 3 Brake Fluid from an unopened container.
Using a non-Acura brake fluid can cause corrosion
and shorten the life of the system.
 Do not mix different brands of brake fluid; they may not be compatible.
 Make sure the brake fluid is not contaminated with dirt or other foreign matter.
 Do not spill brake fluid on the vehicle; it may damage the paint or plastic. If brake fluid does contact the
paint or plastic, wash it off immediately with water.
 If may be necessary to limit the movement of the release fork with a block of wood to remove all the air
from the system.
 Use fender covers to avoid damaging painted surfaces.
1. Make sure the brake fluid level in the clutch reservoir (A) is at the MAX (upper) l evel line (B).2. Attach the one end of a clear tube to the bleeder
screw (A), and put the other end into a container.
Loosen the bleeder screw to allow air to escape
from the system.
3. Make sure there is an adequate supply of fluid in the reservoir, then slowly push the clutch pedal all
the way down. Before releasing the pedal, have an
assistant temporarily tighten the bleeder screw.
Loosen the bleeder screw, and push the pedal
down again. Repeat this step until no more bubbles
appear at the clear tube.
NOTE: Make sure the fluid level on the reservoir
does not go below MIN.
4. Tighten the bleeder screw securely.
5. Refill the brake fluid in the reservoir to the MAX (upper) l evel line.

NOTE:
 Use fender covers to avoid damaging painted surfaces.
 Do not spill brake fluid on the vehicle; it may damage the paint or plastic. If brake fluid does contact the
paint or plastic, wash it off immediately with water.
 Make sure not to get any silicone grease on the terminal part of the connectors and switches,
especially if you have silicone grease on your hands
or gloves.
1. Remove the clutch line bracket (A) and the slave cylinder (B).
2. Remove the roll pins (A). Disconnect the clutch line (B), and remove the O-ring (C). Plug or wrap the
end of the clutch line with a clean shop towel to
prevent brake fluid from coming out. 3. Install a new O-ring (A) on the clutch line (B), then
connect the clutch line to the slave cylinder (C).
4. Set in new roll pins (D) to the slave cylinder.
5. Pull back the boot (A), and apply s ilicone grease
(P/N 08C30-B0234M) to the boot and the slave
cylinder pushrod (B). Reinstall the boot.
6. Apply a light coat of super high temp urea grease (P/N 08798-9002) to the pushrod of the slave
cylinder (C) and the release fork (D).
7. Install the slave cylinder and the clutch line bracket (E).
Replace.
