Known issues on the 1999 C2500 Suburban. One owner complaint is on the NHTSA record for this model year, and it concerns the service brakes. A single report says little on its own, but braking is where a wagon this heavy is most easily overworked, so the brake chapter is a sensible place to start with any used example. It covers hydraulic components, the friction hardware, the parking brake, adjustment and bleeding procedures, wear specifications, torque values and the diagnostic routines that separate a hydraulic fault from a mechanical one.
