2004 Jeep Wrangler Owner's Manual - Page 177

STARTING AND OPERATING 177 If the parking brake is not completely released, the BRAKE warning light will remain on. NOTE: Your vehicle has automatically adjusting rear brakes and we do not recommend any adjustment other than the maintenance performed by your authorized dealer. ABOUT YOUR BRAKES Your vehicle is equipped with power assisted brakes as standard equipment. In the event power assist is lost for any reason (for example, repeated brake applications with the engine off), the brakes will still function. The effort required to brake the vehicle will be much greater than that required with the power system operating. WARNING! Riding the brakes can lead to brake failure and possibly an accident. Driving with your foot resting or riding on the brake pedal can result in abnormally high brake temperatures, excessive lining wear, and possible brake damage. You wouldn't have your full braking capacity in an emergency. If either of two hydraulic systems lose normal capability, the remaining system will still function with some loss of overall braking effectiveness. This will be evident by increased pedal travel during application and greater pedal force required to slow or stop. 5
