Do not allow brake fluid to come into contact with the paint as it will damage the finish. Removal: Release the fasteners and remove the trim panel above the driver's pedals. Disconnect any electrical connectors as the panel is withdrawn. Release the clips, remove the plastic cover, and then remove the brake fluid reservoir cap. Siphon out enough fluid so that the level is below the level of the reservoir fluid hose connection to the clutch master cylinder. Disconnect the clutch master cylinder hose from the brake fluid reservoir. Be prepared for fluid spillage and plug the open end of the hose to prevent dirt entry. Unscrew the mounting nuts and push back the bolts securing the master cylinder to the pedal bracket in the footwell. Using an 8 mm socket, squeeze together the ends of the pin, then press out the master cylinder pushrod pivot pin from the clutch pedal. Using a small screwdriver, pry out the retaining clip and pull the hydraulic pressure line from the master cylinder. Withdraw the master cylinder and ease the fluid supply hose through the firewall grommet, taking care not to strain the pipe. Do not pull the hose completely through the grommet. Be prepared for fluid leaks. Pull the supply hose from the top of the master cylinder, leaving the hose in place in the firewall grommet for reassembly. Be prepared for fluid spillage. Depress the locking tab and disconnect the master cylinder switch wiring plug if equipped. If required, carefully release the clips and detach the switch from the cylinder. Inspection: Inspect the master cylinder for fluid leaks and damage, and replace if necessary. At the time of writing, no spare parts were available for the master cylinder, and if faulty, the complete unit must be replaced. Check with your local dealer or parts supplier. Installation: Installation is the reverse of removal, noting the following points: Take care not to strain the master cylinder fluid pipe during installation. Top off the level in the brake fluid reservoir, then bleed the clutch hydraulic system.
