When I bought it the rear brake didn't work at all as expected but my front's worked great. Then they started making a grinding or a squealing noise when I pulled them in. Just today I was riding down my street and pulled the brakes and they grinded real loud so I let out of them and when I pulled them in, they were hard then they were like pulling in nothing and stopped working. Now I have no brakes at all. I adjusted the front brake all the way tight. The little adjustment thing was on the last thread and the would work but I didn't trust it so I just screwed it back in and there is like an inch of play in the lever. Could the cable be snapped or just need pads? It's a 2000 Yamaha Blaster so it has the sh*t brakes.
