1998 GMC B7 Recalls — Canada & USA

The 1998 GMC B7 has two recalls, both involving the anti-lock brake system, where faults can cause the brakes to underperform and extend stopping distances, raising the risk of a crash. In the first issue, damaged or chafed wheel speed sensor wires can trigger unwanted ABS activation at low speeds, causing the system to bleed air pressure from the brake modulators at one or more wheels and reducing braking force. In the second, the wiring harness that controls the front brakes can chafe and short to ground, shutting off the ABS entirely and reducing front braking capability. Both issues point to the same real-world result: the truck may need more distance to stop than expected.
