Since October 1992, to improve the efficiency of the working and parking brake mechanisms of the rear wheels, calipers of a modified design were installed, the external difference of which from the caliper of the previous design is the presence of a screw-in holder for the parking brake cable instead of a holder made integral with the caliper body.
Redesigned calipers are not interchangeable with old design calipers.
