To complete the work you will need a special key by 10 mm for brake pipe fittings.
Removal
1. Prepare the car for work (see "Preparing the car for maintenance and repair").
2. Using a rubber bulb or syringe, remove brake fluid from the master brake cylinder reservoir.
3. With a special key by 10 mm we loosen the tightening of the fittings of the four brake pipes of the master brake cylinder.
4. With an open-end wrench by 10 mm we completely unscrew the fittings of the four tubes. Carefully, without bending the tubes too much, we move them away from the main brake cylinder.
5. Key by 17 mm we unscrew the two nuts that secure the main brake cylinder to the vacuum booster housing.
6. Remove the master brake cylinder assembly with the reservoir from the vacuum booster.
7. Clamp the cylinder in a vice. Tilt the tank to the side and remove its pipes from the rubber sealing bushings.
Installation
1. Assemble and install the master brake cylinder in the reverse order.
Before installing the reservoir on the new brake cylinder, wet the reservoir pipes with clean brake fluid.
We tighten the brake pipe fittings with a special key.
2. Fill the reservoir with fresh brake fluid and bleed the hydraulic drive of the brake system (see "Hydraulic brake drive - bleeding").
3. Check for fluid leaks at the points where the brake pipes are connected to the master brake cylinder.
