please help me with this brake system (drum brakes?)
My mom got this bike for herself, it's really old and it's really really heavy bike...
There are several things I need to fix on this bike and one of the first things is brakes!
I've never fixed this kind of breaks. The main problems it has is:
1) back brake even on very light touch brakes very tightly and it just freezes the wheel and you may even jump forward a little
2) front brake has a terrible noise that will blow your brains out
I took apart only back brake and found this mechanism, that looks like car's brakes for me...
the material that is used to rub against metal, seems to be fine and still a lot...
what would help?
