Installation
1. Before installing a new vacuum booster, it is recommended to check with a caliper the protrusion of the rod head relative to the plane on the housing. Value A should be in the range of 1.05-1.25 mm.
2. If the protrusion does not correspond to the above, we adjust it by turning the stem head with a key by 7 mm. We hold the stem with pliers from turning.
3. Installation of the vacuum booster is carried out in the reverse order.
4. We pump the hydraulic brakes (see "Hydraulic brakes - pumping and replacing brake fluid").
