Hello, Bike: Hyosung Gt250r 06 I have a problem with the rear brake. It originally was working fine, though there was prehaps an inch of depressing the lever before it started to brake. Then one day after riding for 45 minutes, the brake got stuck on after stopping at the lights, just near home luckly as it got progressively worse everytime I used it. When I came back the next morning the brake had released and I could push it in neutral fine. Now there was only about a cm at the end of the levers motion where the brake would engage. So about 2-3 inches of lever travel. I attempted to bleed the brakes and on the first press of the lever about an inch of fluid came out, then no more would come out. Got help from someone that has bleed brakes before and this time didn't get anything using a one way valve and pumping like mad. Now the brake doesn't work at all. No leaking fluid that we could see. Question: Has anyone experienced a similar problem and is it likely the master cylinder? Just thought I'd check before I spend the money on the part.
