REMOVAL & INSTALLATION
- Disconnect the negative battery cable.
- Drain or siphon the fluid from the clutch master cylinder.
- On 1987-1990 models, remove the reservoir tank.
- Using a flare nut or line wrench, disconnect the hydraulic line to the clutch release from the master cylinder.
Do not spill brake fluid on the painted surfaces of the vehicle. If this occurs, wash it off immediately using plenty of clean water.
- From inside the car, remove the clevis pin clip and the clevis pin. If necessary, remove the underdash panel and the air duct for more clearance.
- Unfasten the bolts which secure the clutch master cylinder to the firewall. Withdraw the assembly from the firewall side.
- Install the master cylinder with its retaining nuts to the firewall. Torque them to 9 ft. lbs. (13 Nm).
- Connect the hydraulic line from the clutch release cylinder to the master cylinder.
- Connect the clevis, then install the clevis pin and clip.
- Fill the reservoir with clean, fresh brake fluid, then bleed the system.
- Check the cylinder and the hose connection for leaks.
- Adjust the clutch pedal.
- Reinstall the air duct and underdash cover panel, if applicable.

Refer to the exploded view of clutch master cylinder components as a guide for the overhaul procedure.
- Clamp the master cylinder body in a vise with protected jaws.
- On 1991-1994 models, use a pin punch and hammer to drive out the slotted spring pin retaining the reservoir. Do the same for 1987-1990 models to remove the inlet union.
- Remove the snapring and remove the pushrod/piston assembly.
- Inspect the master cylinder bore for scoring, grooves or corrosion. If any of these conditions are observed, replace the cylinder. Inspect the piston, spring, push rod and boot for damage or wear. Replace any parts which are worn or defective.
- Before reassembly, coat all internal parts with clean brake fluid.
- Install the piston assembly in the cylinder bore.
- Install the pushrod, then secure it with the snapring.
- Install the reservoir or inlet union. Drive in the slotted spring pin using a pin punch and hammer.
