Known issues on the 1998 K1500 Suburban. A single owner complaint is logged with NHTSA for this model year, and it concerns the service brakes. Brake work is set out here in full, from pedal and booster checks through master cylinder and caliper overhaul to rotor and drum measurement, with the friction material specifications and the torque values for every fastener involved. The antilock content adds its own diagnostic charts and component tests, so a soft pedal or a warning lamp can be traced to a cause before parts are replaced.
