Hi All, I'm new to the board and new to riding. I just picked up a '98 KX-125 and it has been running great for the last 3 months.. No problems. Last weekend while at the track I lost my rear brake. Now When I depress the rear lever I can hear air coming from the Master Cylinder. Is this supposed to be happening? I hadn't noticed it before but I haven't been getting real close to the rear MC whole braking either. From what I know of brake systems this does not sound good but before I start to tear everything apart I thought I would check with you all. In bleeding the brakes I have only been able to get a small amount of pressure to the caliper.
Thanks for the help in advance. This looks like a great group of people here.
