my back blaster brakes keep locking up and wont let go. how do i fix this problem

 

The blaster brakes suck big time. The best way to fix the problem in the rear is to eliminate the stock brake cable that goes from the handle bars to the caliper. Motion pro makes a cable for the blaster called a shorty brake cable that only goes from the foot peg back. Using this cable and making sure that you keep the rear caliper clean and well greesed will help alot.
