One problem related to power assist brake has been reported for the 1999 Nissan Sentra. The most recently reported issues are listed below.
The stopping distance for this sub-compact at 30 mph is exorbitant. My accident was the result of running out of braking space on a damp road. Everyone with abs equipped vehicles were able to swerve out of the road to avoid accident however my standard brakes couldn't compete with their manueverability, especially when the brakes work like I have 50k miles w/o servicing.
