Abstract
A method for transferring brake fluid into a wheel brake cylinder of a brake system of a vehicle includes: controlling a switchover valve, via which a brake circuit having the wheel brake cylinder is connected to a main brake cylinder, into a closed state; subsequently reducing a booster force of a brake force booster, which is exerted upon an adjustable piston of the main brake cylinder; controlling a high-pressure switchover valve to a partially opened state after the reduction of the booster force of the brake force booster; and sucking in brake fluid via the partially opened, high-pressure switchover valve and pumping the brake fluid into the at least one wheel brake cylinder.
