Hey guys, so I was out at Big Horn for practice Sunday night. After my warm up laps I cam into the pits, changed out my sweat shirt for a jersey, and tightend up my boots. When I went back out, a half lap later my brakes just went out. No compression on my brakes at all. The pads are fine and so is the caliper assessembly. I checked the brake line, in perfect condition. Not blocked what so ever and no leaks. SO it must be the fluid resavoir that connects the rear brake pedal to the line and sends the brake fluid to the calipers. I drained the fluid and the fluid is NOT getting to the line. I blew it out with an air compresser and nothing. I filled the cap where the resavior glass is, nothing, and filled it were the brake line hooks in. I don't know if I was spilling the fluid or if it was leaking out the bottom. I really don't know, so I think I will try filling it in there again tomarrow. I really want to know what you guys think is the problem. Thanks for all your help in advance.
