My daughter just got in from college with her '86 325es and I noticed the brakes work but go almost all the way to the floor. The master cylinder is full and no leaks. They don't get harder if I pump them. The vacuum booster is getting vacuum and I don't hear any leaking but not sure. I'm wondering if it's the master brake cylinder or possibly the vacuum booster? Does anyone have ideas? Much thanks!
yea my brakes would go all the way to the floor without stoping the car, scary shit. i just replaced the brake master cylinder it was all fixed. easy job not to hard to replace if you know what u are doing.
