Took it to local Pepboys....asked their senior most tech. to look at it, he knows BMWs. Diagnosed as I thought...front right calliper frozen & rotors & brakes worn out, & rear susp big coil spring (seats only on a rubber disk...thanks to BMW) slipped off center. Back on road for $1600 -all 4 new rotors & brakes & 2 front callipers....brought him some parts from dealer & he also reseated the coil spring. Dealer said $3K for the same service!!
