I have a '96 Mazda B2300 Series. It is a 5 speed. When I put it in reverse to back out of the driveway, it makes this horrible grinding noise. When I hit the break it skids. I put it back in first gear to go back up the driveway with no problems. Please help. I dont know what other info to tell. I had the slave cylinder (sp?) replaced and a new clutch kit put in it this summer. Even my brake lines are totally new. Im not even due for another oil change yet. Maybe they would have noticed something. ?????
