To perform the work you will need a special 13 mm key for pipeline fastening fittings and a rubber bulb (or syringe).
Removal
1. Prepare the car for work (see "Preparing the car for maintenance and repair").
2. Remove the air intake system muffler and the air filter housing (see "Air filter - removal and installation").
3. Unscrew and remove the reservoir cap. Using a syringe or rubber bulb, remove the brake fluid from the reservoir and replace the cap.
4. Press the lock and disconnect the wiring harness connector from the sensor.
5. Using a special 13 mm wrench, unscrew the fittings of the two brake pipes...
...and carefully move the tubes away from the cylinder, without bending them too much.
Warning! Do not allow brake fluid to come into contact with the vehicle body, as it may damage the paintwork. If brake fluid does come into contact with the paintwork, wash it off as quickly as possible with plenty of water.
6. Using a 13 mm socket wrench, unscrew the two nuts securing the master brake cylinder.
7. Remove the master brake cylinder together with the reservoir.
8. If necessary, remove the tank.
Installation
Note: The connection between the master cylinder and the brake booster is sealed with a rubber ring. If damaged, the ring must be replaced.
1. Install the main brake cylinder in the reverse order. Tighten the cylinder mounting nuts to 21 Nm, and the tube fittings to 14 Nm.
2. Connect the wiring harness connector to the sensor.
3. Fill the reservoir with new brake fluid and bleed the hydraulic drive of the brake system (see "Hydraulic brake drive - bleeding").
