Draw out the hydraulic fluid from the clutch master cylinder reservoir with a syringe. Disconnect the clutch fluid hydraulic line by loosening the hydraulic line retaining nut with a flare nut wrench and removing the two mounting nuts, using a flare-nut wrench to protect the tube nut. Have rags handy, as some fluid will be lost during this process. Working inside the passenger compartment, remove the left lower finish panel(s). Disengage the return spring, remove the cotter pin and clevis pin to disconnect the clutch master cylinder pushrod from the clutch pedal, then pry off the return spring and push out the clevis pin. Remove the master cylinder mounting nuts and detach the master cylinder from the firewall. Installation is the reverse of removal, ensuring the master cylinder mounting nuts are tightened. Fill the clutch master cylinder reservoir with the specified fluid and bleed the clutch system.

To remove the Clutch Master Cylinder, start by releasing the spring clip on the Clutch Hose at the top of the cylinder and disconnecting the hose. Clamp the fluid supply hose or use a plug to prevent fluid loss. Unscrew the slave cylinder supply pipe union at the side of the master cylinder, using penetrating fluid if necessary. Inside the car, move the driver's seat fully to the rear and remove the pedal return spring with needle-nosed pliers. Remove the spring clip and clevis pin to detach the clutch pedal. Remove the two master cylinder mounting nuts inside the car and withdraw the master cylinder. If the master cylinder is faulty, it will need to be replaced. To refit, tighten the mounting nuts and fluid pipe union to the specified torque. Ensure the fluid hose connection is clean and secure, and bleed the clutch upon completion.

To disconnect and remove the clutch master cylinder, begin by disconnecting the negative cable from the battery. Then, disconnect the hydraulic line at the clutch master cylinder, using a flare-nut wrench if available to prevent rounding off the fitting.

Moving to the underside of the dash, remove the nuts securing the master cylinder to the firewall, ensuring not to spill any fluid during the removal. For installation, position the master cylinder on the firewall and install the mounting nuts finger-tight. Connect the hydraulic line to the master cylinder, adjusting the cylinder position as needed to properly thread the fitting into the bore, ensuring it is not cross-threaded. Tighten the mounting nut(s) and the hydraulic line fitting securely. Connect the pushrod to the clutch pedal. Fill the clutch master cylinder reservoir with brake fluid that conforms to DOT specifications and proceed to bleed the clutch system. Finally, check the clutch pedal height and free play, making adjustments if necessary.
