BMW: breaks, 5th gear, heavy load

Question
After coming to a full stop light, I start drivign away, but it feels like the car is not moving as fast as it should (especially on 4 and 5th gear). It feels as if the break was locked or as if the car was pulling a heavy load. Is my break locking?

Answer
Carlos,
 It's hard for me to tell, especially without driving or seeing the car.

 When you get done driving the car (for 10-15 minutes), get out and feel of all the wheels.  If one is considerably warmer than the others, you probably have a brake sticking on that wheel.

 Good luck,
