To remove the pressure regulator, you must:
- Add brake fluid up to the upper mark on the reservoir surface. Place a circle of foil under the cork and squeeze it to seal the tank. If the tank is sealed, then after unscrewing the pipelines from the pressure regulator, much less liquid will flow out of it.
- Using a wrench, unscrew the four brake pipes from the pressure regulator, noting their location.
- Remove spring 3 and unscrew the bolt securing the regulator housing.
The pressure regulator is mounted in the reverse order of removal.
After installing the regulator, it is necessary to remove air from the system (see below).
The pressure regulator must be checked at a service station, while the adjustment consists in changing the preload of the spring 3 of the regulator.
