Master Cylinder — Removal and Installation (Opel Vectra A)

Removal

1. Disconnect the negative cable from the battery.

2. Press the brake pedal several times to relieve the vacuum in the booster.

3. Disconnect the electrical connector from the brake fluid level sensor in the filler cap of the master cylinder reservoir.

4. If possible, use a dropper or old hydrometer to suck the brake fluid out of the cylinder reservoir - this will reduce fluid loss during the next procedure.

5. Place a suitable container under the master cylinder to catch the brake fluid that will be released.

6. Apply alignment marks to the brake pipes, then unscrew the connecting nuts and disconnect the pipes from the master cylinder.

7. Unscrew the two mounting nuts and remove the master cylinder from the struts on the vacuum booster unit (see illustration).



8. Clean the outside of the cylinder, then carefully remove the reservoir and seals from it, using a screwdriver as a lever.

9. If required, on models without ABS the master cylinder can be disassembled as described in Chapter 16.

10. On models with ABS, overhaul of the master cylinder is not possible (see Chapter 17).
