brakes stuck

happened on my old blaster growing up. some might cringe when i say this bit i took a screw driver and a mallet and beat on it at every angle till it released hold on the disc, ofcourse this was on the mechanicals back in the day
 
Rear brakes aren't that hard to fix, lots of times its just a matter of neglect, a good cleaning might do the job till you upgrade. I:I
