Withdrawal
1. Disconnect wire from «negative» battery terminals.
2. Disconnect the working fluid supply tube from the master cylinder and plug the tube opening.
3. Remove left instrument panel lower trim to gain access to master cylinder mounting.
4. Disconnect the tube from the end of the master cylinder by unscrewing the fastening nut and plug the tube hole.
5. Disconnect the pushrod fork from the clutch pedal by removing the circlip and removing the pin.
6. Remove the two mounting bolts and remove the master cylinder from the vehicle.
Disassembly
1. Clean the master cylinder of dirt.
2. Remove the dust cover from the master cylinder body.
3. Remove the retaining ring and remove the pusher from the housing.
4. Using a suitable rod, push the piston out of the cylinder body through the end hole until it emerges from the cylinder. Finally remove the piston from the cylinder body together with the return spring.
5. Remove the spring from the piston and cuff.
Inspection and Troubleshooting of Master Cylinder Parts
1. Rinse the master cylinder parts with clean brake fluid and dry.
2. The mirror of the main cylinder should not have scratches, shells and foci of corrosion. If these defects are present, the cylinder must be replaced. There must be no mechanical damage on the threaded parts of the cylinder.
3. The cuffs of the master cylinder must be resilient and elastic. Torn, swollen and hardened cuffs, as well as those with marks on the working surfaces, must be replaced.
4. The end of the pusher and the mating surface of the piston should not have obvious traces of one-sided wear. The surfaces of the piston in contact with the cylinder face must also show no signs of wear on one side. Otherwise, the pusher and piston are recommended to be replaced. The piston valve must show no visible signs of deformation and must fit snugly against the piston end.
5. The mudguard of the master cylinder must be free of cracks and through holes. It should be installed on the pusher and master cylinder body with a slight interference. Otherwise, replace the cover.
6. The spring must have elastic properties. Spring breakage is not allowed.
7. The thread of the tips of the tube and hose must not be mechanically damaged. The fitting of the tips must not have cracks and traces of visible deformation.
Assembly
1. Lubricate cuff clean brake fluid and install it on the spring, orienting the working edge to the spring.
2. Insert the spring carefully into the cylinder body.
3. Lubricate the cuff with clean brake fluid and install it on the piston, orienting the working edge towards the spring.
4. Insert the piston with the bypass ring put on it into the cylinder body.
5. Install the locking bracket on the pusher, if it was removed.
6. Insert the tappet into the cylinder body and install the circlip.
7. Install the dust cover on the cylinder body.
Installation
Install clutch master cylinder in reverse order. At the same time, tighten the master cylinder mounting bolts to a torque of 20 Nm (2.0 kgf·m). After installation, bleed the clutch hydraulic (cm. subsection 7.3.4).
Clutch pedal free play adjustment
1. Loosen the pusher fork locknut.
2. By unscrewing or screwing the pusher by hand or using pliers, achieve an excess of the position of the clutch pedal relative to the brake pedal by 10 mm.
3. Tighten locknut.
