Clutch Master Cylinder Replacement

NOTE:
^ Use fender covers to avoid damaging painted surfaces.

1. Remove the brake fluid from the clutch master cylinder reservoir with a syringe.
2. Make sure you have the anti-theft codes for the audio unit and the navigation system, then write down the audio presets.
3. Disconnect the negative cable from the battery, then disconnect the positive cable.
4. Remove the battery.
5. Remove the air cleaner assembly.
6. Remove the battery base.
7. Pry out the lock pin (A), and pull the pedal pin (B) out of the yoke. Remove the master cylinder mounting nuts (C).

10. Remove the clutch line clips (C).
11. Remove the clutch master cylinder (D).
12. Disconnect the reservoir hose (A), then remove the retaining clip (B), and clutch line (C) from the clutch master cylinder (D). Plug or wrap the end of the reservoir hose and clutch line with a shop towel to prevent brake fluid from coming out.





13. Remove the O-ring (E) and clutch master cylinder seal (F) from the clutch master cylinder.
14. Install the new O-ring (A) and clutch master cylinder seal (B) to the clutch master cylinder (C).





15. Install the clutch line (D), then instill the new retaining clip (E). Connect the reservoir hose (F).
16. To prevent the retaining clip (A) from coming off, pry apart the tip of the retaining clip (B) with a screwdriver.

18. Install the clutch line clips (B) and clutch line bracket (C).
19. Install the reservoir mounting bolt (D).
20. Make sure the hose clamps (A) are positioned on the master cylinder (B) and reservoir (C) as shown.

22. Apply grease to the pin (B), and slide it into the yoke, then install a new lock pin (C).
23. Adjust the clutch pedal, clutch pedal position switch, and clutch interlock switch.
24. Bleed the clutch hydraulic system.
^ Attach a clear tube to the bleeder screw (A), and suspend the tube in a container of brake fluid. Loosen the bleeder screw to allow air to escape from the system. Then tighten the bleeder screw securely.
^ Make sure there is an adequate supply of fluid in the reservoir, then slowly pump the clutch pedal until there are no more bubbles in the bleeder tube.
^ It may be necessary to limit the movement of the release fork (B) with a block of wood to remove all the air from the system.
^ 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.
