The antilock brakes on my 1998 Chevrolet Suburban activate at low speeds . If this condition occurs where stopping distance is limited a crash could occur. . This is a for real safety issue and is documented in nhts item number 10000062. Noticed on the internet someone posted in ontario canada there is a gm recall for the speed sensors and corrosion. . I can not believe a issue involving brakes is not on a recall. . . . . I asked a service manager about the problem I'm having and he quoted the speed sensor right away. . . Come on gm knows they have a problem. . . . Going to take the vehicle to gm next week and ask to talk to the zone manager .
