I was leaving greenville, s.c.and the left side brakes lock and pulled me into the left lane of traffic and i took my foot off the gas and the car free rolled for a short distance while i got back in my lane. i reapplied the gas and got back up to twenty-five mph and the right side brakes locked. i was only going approximately twenty five mph when all of this occurred. i stopped in the emergency lane and got out of the car. i saw nothing visibly wrong and started up the emergency lane and the brakes continued to lock as i was going up the emergency lane. i got the car to the first exit and took that exit. i parked the car in a private business and had it towed from there. *tr
