Brake help

[hartner62]

My dad bought a generic model wheeler and the back breaks keep locking up. If I bleed the breaks it works perfect until you get about a hour into it and it starts to do it again. Is there anything that you guys can think of that I could do to perm. fix this problem?

A. trade it off

B. don't use rear brake

C. check to make sure master cylinder return isn't plugged and

fluid is flowing back into master cylinder when brake is

released
