The same thing happen to me twice within one week. It is your calipers. Either you need to have them replaced or maybe you can have someone to checked them and see if they can grease them or release them. I hope this works.
My 1995 740i, rear brakes locked on me while driving, no dash light indicators came on. Had to have it towed, I was told my brake fluid was contaminated, and because the brake system is sealed, the master cylinder, 4 calibers, ABS hydraulic unit, brake hoses, new pads and routers in rea all need to be replaced...cost $6k. Please tell me I have an another option!!!!
