2000 GMC Jimmy brakes problems

2000 GMC jimmy experienced a problem with the front right hub and the wheel speed sensor. The consumer was pulling into a parking space and the brake pedal became stiff and or would not activate. The consumer had run into a brick wall and bounced into traffic. The check ABS system light had immediately illuminated. The consumer was then able to apply the brakes and backed into a parking space. The left front hub was replaced days before the consumer purchased the vehicle. The vehicle was also losing coolant.
