Check for lack of leak of brake fluid from the working brake system and its serviceability.
The parking brake needs to be adjusted after removal of the central console and facing of the parking brake.

Check of adjustment of a cable of the parking brake consists in serial pressing by an edge of the screw-driver of the lever of a cable of the parking brake from one emphasis (fig. 15-36) to other (fig. 15-37).
If in the course of check the lever of a cable of an opposite support moves from an emphasis, then the cable is excessively tense therefore it is necessary to adjust it.
Press several times a brake pedal against the stop.
Release the lever of the parking brake.
