Toyota 04311-12080 Master Cylinder Repair Kit

Before beginning this procedure, contact local parts stores and dealers concerning the purchase of a rebuild kit or a new master cylinder. The availability and cost of the necessary parts may dictate whether the cylinder is rebuilt or replaced with a new one. If it is decided to rebuild the cylinder, follow the instructions contained in the rebuild kit. To remove the clutch master cylinder, start by removing the undercover from the dash panel to gain access to the top of the clutch pedal. Then, working under the dash panel, disconnect the pushrod for the top of the clutch pedal, which is held in place with a clevis pin. Next, disconnect the hydraulic line at the clutch master cylinder and seal the end to prevent the entry of dirt and loss of fluid. The master cylinder is located on the firewall, just to the right of the brake master cylinder. Use a flare nut wrench on the fitting to prevent rounding it off. Have rags handy as some fluid will be lost as the line is removed. After that, remove the two nuts that secure the master cylinder to the engine firewall. One nut is in the engine compartment and the other is inside the vehicle above the clutch pedal. Carefully remove the master cylinder, being cautious not to spill any fluid. To install the new master cylinder, position it on the firewall and install the two mounting nuts finger tight. Connect the hydraulic line to the master cylinder, making sure not to cross thread the fitting. Then, tighten the two mounting nuts. Inside the vehicle, connect the pushrod to the clutch pedal and install the undercover. Finally, fill the clutch master cylinder reservoir with brake fluid conforming to DOT 3 specifications and bleed the clutch system.
