Abstract
A vehicle brake control device is configured to correct deformation failure of a seal member and inhibit insufficient pullback of a pressing member caused by insufficient deformation of the seal member. Within a time period from a start of a lock operation to an end of the release operation, a W/C pressure is automatically increased and insufficient deformation of a seal member is corrected. It is thus possible to generate a large restoring force by the seal member when pulling back a piston, and the piston can be pulled back based on the restoring force. The piston is therefore sufficiently moved, and it is possible to inhibit insufficient piston pullback. Further, it is possible to cause a brake pad to be separated from a brake disc by a predetermined distance, and it is possible to inhibit a feeling of drag of a brake from being imparted to a driver.
