Remove and replace the clutch master cylinder assembly, including disconnection of the hydraulic line and pushrod from the clutch pedal.

Warnings

Tools required

Parts

• Clutch master cylinder × 1 — Use OEM specification
• Master cylinder pushrod retaining clip × 1 — Use OEM specification

Fluids

• brake — 0.25 qt

Preparation

1. Park vehicle on level ground and set parking brake.
2. Open hood and locate clutch master cylinder reservoir on driver's side firewall.
3. Place protective covering over left front fender area.
4. Gather all tools and new parts before beginning.

Procedure

1. 1

   Drain clutch fluid reservoir
   Use a turkey baster or fluid syringe to remove as much fluid as possible from the clutch master cylinder reservoir. Dispose of old fluid properly. This minimizes spillage during removal.
2. 2

   Disconnect hydraulic line from master cylinder
   Working under the hood, locate the hydraulic line connection at the master cylinder body. Use a flare nut wrench to loosen and disconnect the hydraulic line fitting. Be prepared for residual fluid to drain. Cap or plug the line end to prevent contamination and further fluid loss.
   ⚠Use a flare nut wrench, not a standard open-end wrench, to prevent rounding off the hydraulic line fitting.

3. 3

   Access clutch pedal area
   Open driver's door and position yourself to access the upper clutch pedal area under the dash. You may need to remove the driver's side lower dash panel for better access. This panel is typically secured with fasteners along its perimeter. Inspect for screw or bolt locations and remove as needed.
4. 4

   Disconnect pushrod from clutch pedal
   Locate the master cylinder pushrod connection at the top of the clutch pedal arm. Remove the retaining clip securing the pushrod clevis pin to the pedal. Slide the clevis pin out and disconnect the pushrod from the pedal. Note the orientation of all components for reassembly.
5. 5

   Remove master cylinder mounting fasteners
   Return to the engine bay. Locate the 2 mounting bolts securing the clutch master cylinder to the firewall. These bolts are accessible from the engine bay side. Remove both mounting bolts completely.

   Master Cylinder Bolts25 Nm (18 lb-ft)
6. 6

   Remove master cylinder assembly
   Carefully pull the master cylinder forward from the firewall, guiding the pushrod through the firewall opening. Remove the assembly from the vehicle. Allow any remaining fluid to drain into the catch pan.
7. 7

   Inspect and prepare new master cylinder
   Inspect the new master cylinder for shipping damage and verify it matches the original. Check that the pushrod length matches the original unit. If the new cylinder is shipped dry, verify the reservoir cap is secure to prevent contamination during installation.
8. 8

   Install new master cylinder
   Guide the pushrod of the new master cylinder through the firewall opening from the engine bay side. Align the mounting holes with the firewall and start both mounting bolts by hand. Torque the mounting bolts to specification.

9. 9

   Connect pushrod to clutch pedal
   Working from inside the vehicle, align the pushrod clevis with the clutch pedal arm. Insert the clevis pin through the pedal arm and pushrod clevis. Install a new retaining clip to secure the pin. Verify the connection is secure and the pushrod moves freely with pedal motion.
10. 10

    Reinstall lower dash panel
    If the driver's side lower dash panel was removed in step 3, reinstall it now using the original fasteners. Ensure all clips and fasteners are properly seated.
11. 11

    Connect hydraulic line
    Working in the engine bay, connect the hydraulic line to the new master cylinder. Thread the fitting by hand first to avoid cross-threading, then tighten to specification using a flare nut wrench.

    Fill and bleed clutch hydraulic system
    Fill the clutch master cylinder reservoir with fresh DOT 4 brake fluid to the full mark. Bleed the clutch hydraulic system at the slave cylinder bleeder valve: have an assistant pump the clutch pedal 3-4 times and hold it down, then open the bleeder valve until fluid flows and close it before the pedal is released. Repeat until no air bubbles appear in the fluid. Maintain reservoir level throughout bleeding. Torque bleeder valve to 5-6 Nm when complete.

Reassembly

1. Reassembly is covered in the installation steps above.
2. Ensure all hydraulic connections are tight and leak-free.
3. Verify clutch pedal returns fully after each stroke and has proper free play at the top of travel.
4. Wipe any spilled brake fluid from painted surfaces immediately with water.

Verification

• Start engine and verify clutch pedal feels firm with normal resistance.
• Check for fluid leaks at the master cylinder body, mounting area, and hydraulic line connection.
• Test clutch engagement and disengagement by shifting through all gears with engine running.
• Verify clutch pedal returns fully to rest position without binding.
• Check fluid level in reservoir after test and top off if needed.
• Test drive vehicle to confirm smooth clutch operation under load.
