A process is disclosed for restoring brake pressure in a brake of a motor vehicle having an antilock brake system which subjects the brake to a brake regulating cycle. The brake regulating cycle comprises a pressure reduction phase, wherein the brake pressure is reduced from a deregulating pressure Pmax to a holding pressure Pmin, a pressure maintenance phase, wherein the holding pressure Pmin is maintained in the brake, and a pressure restoration phase, wherein the brake pressure in the brake is increased. According to the invention, during the pressure restoration phase the brake pressure is increased with a steep pressure gradient PGH during a first pressure increase stage until a pressure level PK is reached. Thereafter the brake pressure is increased with a low pressure gradient PGN in a second pressure increase stage. The steep pressure gradient PGH is calculated as a function of Pmax and Pmin of the last regulating cycle, while the low pressure gradient PGN is calculated as a function of Pmax of the last regulating cycle. Alternatively, PGH is calculated as a function of the average value of Pmax and Pmin for several previous regulating cycles, while PGN is calculated as the average value of Pmax for several previous regulating cycles.
